Publishing is the dissemination of literature, music, or information. It is the activity of making information available to the general public. In some cases, authors may be their own publishers, meaning originators and developers of content provide media to deliver and display the content for the same; the word "publisher" can refer to the individual who leads a publishing company or an imprint or to a person who owns/heads a magazine. Traditionally, the term refers to the distribution of printed works such as newspapers. With the advent of digital information systems and the Internet, the scope of publishing has expanded to include electronic resources such as the electronic versions of books and periodicals, as well as micropublishing, blogs, video game publishers, the like. Publishing includes the following stages of development: acquisition, copy editing, printing and distribution. Publication is important as a legal concept: As the process of giving formal notice to the world of a significant intention, for example, to marry or enter bankruptcy As the essential precondition of being able to claim defamation.
Self-publishing: The author has to meet the total expense to get the book published. The author should retain full rights known as vanity publishing. Publishing became possible with the invention of writing, became more practical upon the introduction of printing. Prior to printing, distributed works were copied manually, by scribes. Due to printing, publishing progressed hand-in-hand with the development of books; the Chinese inventor Bi Sheng made movable type of earthenware circa 1045, but there are no known surviving examples of his printing. Around 1450, in what is regarded as an independent invention, Johannes Gutenberg invented movable type in Europe, along with innovations in casting the type based on a matrix and hand mould; this invention made books less expensive to produce, more available. Early printed books, single sheets and images which were created before 1501 in Europe are known as incunables or incunabula. "A man born in 1453, the year of the fall of Constantinople, could look back from his fiftieth year on a lifetime in which about eight million books had been printed, more than all the scribes of Europe had produced since Constantine founded his city in A.
D. 330."Eventually, printing enabled other forms of publishing besides books. The history of modern newspaper publishing started in Germany in 1609, with publishing of magazines following in 1663. Publishing has been handled by publishers, with the history of self-publishing progressing until the advent of computers brought us electronic publishing, made evermore ubiquitous from the moment the world went online with the Internet; the establishment of the World Wide Web in 1989 soon propelled the website into a dominant medium of publishing, as websites are created by anyone with Internet access. The history of wikis started shortly thereafter, followed by the history of blogging. Commercial publishing progressed, as printed forms developed into online forms of publishing, distributing online books, online newspapers, online magazines. Since its start, the World Wide Web has been facilitating the technological convergence of commercial and self-published content, as well as the convergence of publishing and producing into online production through the development of multimedia content.
Book and magazine publishers spend a lot of commissioning copy. At a small press, it is possible to survive by relying on commissioned material, but as activity increases, the need for works may outstrip the publisher's established circle of writers. For works written independently of the publisher, writers first submit a query letter or proposal directly to a literary agent or to a publisher. Submissions sent directly to a publisher are referred to as unsolicited submissions, the majority come from unpublished authors. If the publisher accepts unsolicited manuscripts the manuscript is placed in the slush pile, which publisher's readers sift through to identify manuscripts of sufficient quality or revenue potential to be referred to acquisitions editors for review; the acquisitions editors send their choices to the editorial staff. The time and number of people involved in the process are dependent on the size of the publishing company, with larger companies having more degrees of assessment between unsolicited submission and publication.
Unsolicited submissions have a low rate of acceptance, with some sources estimating that publishers choose about three out of every ten thousand unsolicited manuscripts they receive. Many book publishers around the world maintain a strict "no unsolicited submissions" policy and will only accept submissions via a literary agent; this policy shifts the burden of assessing and developing writers out of the publisher and onto the literary agents. At these publishers, unsolicited manuscripts are thrown out, or sometimes returned, if the author has provided pre-paid postage. Established authors may be represented by a literary agent to market their work to publishers and n
Sweden the Kingdom of Sweden, is a Scandinavian Nordic country in Northern Europe. It borders Norway to the west and north and Finland to the east, is connected to Denmark in the southwest by a bridge-tunnel across the Öresund, a strait at the Swedish-Danish border. At 450,295 square kilometres, Sweden is the largest country in Northern Europe, the third-largest country in the European Union and the fifth largest country in Europe by area. Sweden has a total population of 10.2 million. It has a low population density of 22 inhabitants per square kilometre; the highest concentration is in the southern half of the country. Germanic peoples have inhabited Sweden since prehistoric times, emerging into history as the Geats and Swedes and constituting the sea peoples known as the Norsemen. Southern Sweden is predominantly agricultural, while the north is forested. Sweden is part of the geographical area of Fennoscandia; the climate is in general mild for its northerly latitude due to significant maritime influence, that in spite of this still retains warm continental summers.
Today, the sovereign state of Sweden is a constitutional monarchy and parliamentary democracy, with a monarch as head of state, like its neighbour Norway. The capital city is Stockholm, the most populous city in the country. Legislative power is vested in the 349-member unicameral Riksdag. Executive power is exercised by the government chaired by the prime minister. Sweden is a unitary state divided into 21 counties and 290 municipalities. An independent Swedish state emerged during the early 12th century. After the Black Death in the middle of the 14th century killed about a third of the Scandinavian population, the Hanseatic League threatened Scandinavia's culture and languages; this led to the forming of the Scandinavian Kalmar Union in 1397, which Sweden left in 1523. When Sweden became involved in the Thirty Years War on the Reformist side, an expansion of its territories began and the Swedish Empire was formed; this became one of the great powers of Europe until the early 18th century. Swedish territories outside the Scandinavian Peninsula were lost during the 18th and 19th centuries, ending with the annexation of present-day Finland by Russia in 1809.
The last war in which Sweden was directly involved was in 1814, when Norway was militarily forced into personal union. Since Sweden has been at peace, maintaining an official policy of neutrality in foreign affairs; the union with Norway was peacefully dissolved in 1905. Sweden was formally neutral through both world wars and the Cold War, albeit Sweden has since 2009 moved towards cooperation with NATO. After the end of the Cold War, Sweden joined the European Union on 1 January 1995, but declined NATO membership, as well as Eurozone membership following a referendum, it is a member of the United Nations, the Nordic Council, the Council of Europe, the World Trade Organization and the Organisation for Economic Co-operation and Development. Sweden maintains a Nordic social welfare system that provides universal health care and tertiary education for its citizens, it has the world's eleventh-highest per capita income and ranks in numerous metrics of national performance, including quality of life, education, protection of civil liberties, economic competitiveness, equality and human development.
The name Sweden was loaned from Dutch in the 17th century to refer to Sweden as an emerging great power. Before Sweden's imperial expansion, Early Modern English used Swedeland. Sweden is derived through back-formation from Old English Swēoþēod, which meant "people of the Swedes"; this word is derived from Sweon/Sweonas. The Swedish name Sverige means "realm of the Swedes", excluding the Geats in Götaland. Variations of the name Sweden are used in most languages, with the exception of Danish and Norwegian using Sverige, Faroese Svøríki, Icelandic Svíþjóð, the more notable exception of some Finnic languages where Ruotsi and Rootsi are used, names considered as referring to the people from the coastal areas of Roslagen, who were known as the Rus', through them etymologically related to the English name for Russia; the etymology of Swedes, thus Sweden, is not agreed upon but may derive from Proto-Germanic Swihoniz meaning "one's own", referring to one's own Germanic tribe. Sweden's prehistory begins in the Allerød oscillation, a warm period around 12,000 BC, with Late Palaeolithic reindeer-hunting camps of the Bromme culture at the edge of the ice in what is now the country's southernmost province, Scania.
This period was characterised by small bands of hunter-gatherer-fishers using flint technology. Sweden is first described in a written source in Germania by Tacitus in 98 AD. In Germania 44 and 45 he mentions the Swedes as a powerful tribe with ships that had a prow at each end. Which kings ruled these Suiones is unknown, but Norse mythology presents a long line of legendary and semi-legendary kings going back to the last centuries BC; as for literacy in Sweden itself, the runic script was in use among the south Scandinavian elite by at least the 2nd century AD, but all that has come down to the present from the Roman Period is curt inscriptions on artefacts of male names, demonstrating th
The Internet is the global system of interconnected computer networks that use the Internet protocol suite to link devices worldwide. It is a network of networks that consists of private, academic and government networks of local to global scope, linked by a broad array of electronic and optical networking technologies; the Internet carries a vast range of information resources and services, such as the inter-linked hypertext documents and applications of the World Wide Web, electronic mail and file sharing. Some publications no longer capitalize "internet"; the origins of the Internet date back to research commissioned by the federal government of the United States in the 1960s to build robust, fault-tolerant communication with computer networks. The primary precursor network, the ARPANET served as a backbone for interconnection of regional academic and military networks in the 1980s; the funding of the National Science Foundation Network as a new backbone in the 1980s, as well as private funding for other commercial extensions, led to worldwide participation in the development of new networking technologies, the merger of many networks.
The linking of commercial networks and enterprises by the early 1990s marked the beginning of the transition to the modern Internet, generated a sustained exponential growth as generations of institutional and mobile computers were connected to the network. Although the Internet was used by academia since the 1980s, commercialization incorporated its services and technologies into every aspect of modern life. Most traditional communication media, including telephony, television, paper mail and newspapers are reshaped, redefined, or bypassed by the Internet, giving birth to new services such as email, Internet telephony, Internet television, online music, digital newspapers, video streaming websites. Newspaper and other print publishing are adapting to website technology, or are reshaped into blogging, web feeds and online news aggregators; the Internet has enabled and accelerated new forms of personal interactions through instant messaging, Internet forums, social networking. Online shopping has grown exponentially both for major retailers and small businesses and entrepreneurs, as it enables firms to extend their "brick and mortar" presence to serve a larger market or sell goods and services online.
Business-to-business and financial services on the Internet affect supply chains across entire industries. The Internet has no single centralized governance in either technological implementation or policies for access and usage; the overreaching definitions of the two principal name spaces in the Internet, the Internet Protocol address space and the Domain Name System, are directed by a maintainer organization, the Internet Corporation for Assigned Names and Numbers. The technical underpinning and standardization of the core protocols is an activity of the Internet Engineering Task Force, a non-profit organization of loosely affiliated international participants that anyone may associate with by contributing technical expertise. In November 2006, the Internet was included on USA Today's list of New Seven Wonders; when the term Internet is used to refer to the specific global system of interconnected Internet Protocol networks, the word is a proper noun that should be written with an initial capital letter.
In common use and the media, it is erroneously not capitalized, viz. the internet. Some guides specify that the word should be capitalized when used as a noun, but not capitalized when used as an adjective; the Internet is often referred to as the Net, as a short form of network. As early as 1849, the word internetted was used uncapitalized as an adjective, meaning interconnected or interwoven; the designers of early computer networks used internet both as a noun and as a verb in shorthand form of internetwork or internetworking, meaning interconnecting computer networks. The terms Internet and World Wide Web are used interchangeably in everyday speech. However, the World Wide Web or the Web is only one of a large number of Internet services; the Web is a collection of interconnected documents and other web resources, linked by hyperlinks and URLs. As another point of comparison, Hypertext Transfer Protocol, or HTTP, is the language used on the Web for information transfer, yet it is just one of many languages or protocols that can be used for communication on the Internet.
The term Interweb is a portmanteau of Internet and World Wide Web used sarcastically to parody a technically unsavvy user. Research into packet switching, one of the fundamental Internet technologies, started in the early 1960s in the work of Paul Baran and Donald Davies. Packet-switched networks such as the NPL network, ARPANET, the Merit Network, CYCLADES, Telenet were developed in the late 1960s and early 1970s; the ARPANET project led to the development of protocols for internetworking, by which multiple separate networks could be joined into a network of networks. ARPANET development began with two network nodes which were interconnected between the Network Measurement Center at the University of California, Los Angeles Henry Samueli School of Engineering and Applied Science directed by Leonard Kleinrock, the NLS system at SRI International by Douglas Engelbart in Menlo Park, California, on 29 October 1969; the third site was the Culler-Fried Interactive Mathematics Center at the University of California, Santa Barbara, followed by the University of
A CD-ROM is a pre-pressed optical compact disc that contains data. Computers can read—but not write to or erase—CD-ROMs, i.e. it is a type of read-only memory. During the 1990s, CD-ROMs were popularly used to distribute software and data for computers and fourth generation video game consoles; some CDs, called enhanced CDs, hold both computer data and audio with the latter capable of being played on a CD player, while data is only usable on a computer. The CD-ROM format was developed by Japanese company Denon in 1982, it was an extension of Compact Disc Digital Audio, adapted the format to hold any form of digital data, with a storage capacity of 553 MiB. CD-ROM was introduced by Denon and Sony at a Japanese computer show in 1984; the Yellow Book is the technical standard. One of a set of color-bound books that contain the technical specifications for all CD formats, the Yellow Book, standardized by Sony and Philips in 1983, specifies a format for discs with a maximum capacity of 650 MiB. CD-ROMs are identical in appearance to audio CDs, data are stored and retrieved in a similar manner.
Discs are made from a 1.2 mm thick disc of polycarbonate plastic, with a thin layer of aluminium to make a reflective surface. The most common size of CD-ROM is 120 mm in diameter, though the smaller Mini CD standard with an 80 mm diameter, as well as shaped compact discs in numerous non-standard sizes and molds, are available. Data is stored on the disc as a series of microscopic indentations. A laser is shone onto the reflective surface of the disc to read the pattern of lands; because the depth of the pits is one-quarter to one-sixth of the wavelength of the laser light used to read the disc, the reflected beam's phase is shifted in relation to the incoming beam, causing destructive interference and reducing the reflected beam's intensity. This is converted into binary data. Several formats are used for data stored on compact discs, known as the Rainbow Books; the Yellow Book, published in 1988, defines the specifications for CD-ROMs, standardized in 1989 as the ISO/IEC 10149 / ECMA-130 standard.
The CD-ROM standard builds on top of the original Red Book CD-DA standard for CD audio. Other standards, such as the White Book for Video CDs, further define formats based on the CD-ROM specifications; the Yellow Book itself is not available, but the standards with the corresponding content can be downloaded for free from ISO or ECMA. There are several standards that define how to structure data files on a CD-ROM. ISO 9660 defines the standard file system for a CD-ROM. ISO 13490 is an improvement on this standard which adds support for non-sequential write-once and re-writeable discs such as CD-R and CD-RW, as well as multiple sessions; the ISO 13346 standard was designed to address most of the shortcomings of ISO 9660, a subset of it evolved into the UDF format, adopted for DVDs. The bootable CD specification was issued in January 1995, to make a CD emulate a hard disk or floppy disk, is called El Torito. Data stored on CD-ROMs follows the standard CD data encoding techniques described in the Red Book specification.
This includes cross-interleaved Reed–Solomon coding, eight-to-fourteen modulation, the use of pits and lands for coding the bits into the physical surface of the CD. The structures used to group data on a CD-ROM are derived from the Red Book. Like audio CDs, a CD-ROM sector contains 2,352 bytes of user data, composed of 98 frames, each consisting of 33-bytes. Unlike audio CDs, the data stored in these sectors corresponds to any type of digital data, not audio samples encoded according to the audio CD specification. To structure and protect this data, the CD-ROM standard further defines two sector modes, Mode 1 and Mode 2, which describe two different layouts for the data inside a sector. A track inside a CD-ROM only contains sectors in the same mode, but if multiple tracks are present in a CD-ROM, each track can have its sectors in a different mode from the rest of the tracks, they can coexist with audio CD tracks as well, the case of mixed mode CDs. Both Mode 1 and 2 sectors use the first 16 bytes for header information, but differ in the remaining 2,336 bytes due to the use of error correction bytes.
Unlike an audio CD, a CD-ROM cannot rely on error concealment by interpolation. To achieve improved error correction and detection, Mode 1, used for digital data, adds a 32-bit cyclic redundancy check code for error detection, a third layer of Reed–Solomon error correction using a Reed-Solomon Product-like Code. Mode 1 therefore contains 288 bytes per sector for error detection and correction, leaving 2,048 bytes per sector available for data. Mode 2, more appropriate for image or video data, contains no additional error detection or correction bytes, having therefore 2,336 available data bytes per sector. Note that both modes, like audio CDs, still benefit from the lower layers of error correction at the frame level. Before being stored on a disc with the techniques described above, each CD-ROM sector is scrambled to prevent some problematic patterns from showing up; these scrambled sectors follow the same encoding process described in the Red Book in order to be stored
The krona is the official currency of Sweden. Both the ISO code "SEK" and currency sign "kr" are in common use. In English, the currency is sometimes referred to as the Swedish crown, as krona means crown in Swedish; the Swedish krona was the ninth-most traded currency in the world by value in April 2016. One krona is subdivided into 100 öre. However, all öre coins have been discontinued as of 30 September 2010. Goods can still be priced in öre, but all sums are rounded to the nearest krona when paying with cash; the word öre is derived from the Roman gold coin aureus, which in itself comes from the Latin word aurum, meaning gold. The introduction of the krona, which replaced at par the riksdaler, was a result of the Scandinavian Monetary Union, which came into effect in 1876 and lasted until the beginning of World War I; the parties to the union were the Scandinavian countries, where the name was krona in Sweden and krone in Denmark and Norway, which in English means "crown". The three currencies were on the gold standard, with the krona/krone defined as 1⁄2480 of a kilogram of pure gold.
After dissolution of the monetary union in August 1914, Sweden and Norway all decided to keep the names of their respective and now separate currencies. On 11 September 2012, the Riksbank announced a new series of coins with new sizes to replace the 1- and 5-krona coins which arrived in October 2016; the design of the coins follows the theme of singer-songwriter Ted Gärdestad's song, "Sol, vind och vatten", with the designs depicting the elements on the reverse side of the coins. This included the reintroduction of the 2-krona coin, while the current 10-krona coin remained the same; the new coins have a new portrait of the king in their design. One of the reasons for a new series of coins is to end the use of nickel, it is expected that vending machines and parking meters will to a high degree stop accepting coins and accept only bank cards or mobile phone payments. Cash is less used in Sweden, with many young people avoiding cash as much as possible. Between 1873 and 1876, coins in denominations of 1, 2, 5, 10, 25, 50 öre and 1, 2, 10, 20 kronor were introduced.
The 1, 2 and 5 öre were in bronze, the 10-, 25-, 50-öre and 1-krona and 2-krona were in silver, the 10- and 20-krona were in gold. Gold 5-krona coins were added in 1881. In 1873 the Scandinavian Monetary Union currency was fixed so that 2,480 kronor purchased 1 kg of gold. In 2017 the price of gold is 365,289 kronor per kg. So one öre in 1873 bought as much gold as 1.47 krona in 2017. So if it is reasonable to have the smallest denomination coin 1 krona today, in 1873 a reasonable smallest denomination coin was 1 öre. A 10 kr gold coin weighed 4.4803 grams with 900 finess so that the fine weight was 4.03327 grams or 1/248th of a kilogram. In 1902, production of gold coins ceased, was restarted in 1920 and 1925 before ceasing entirely. Due to metal shortages during World War I, iron replaced bronze between 1917 and 1919. Nickel-bronze replaced silver in the 10, 25 and 50 öre in 1920, with silver returning in 1927. Metal shortages due to World War II again led to changes in the Swedish coinage. Between 1940 and 1947, the nickel-bronze 10, 25 and 50 öre were again issued.
In 1942, iron again replaced the silver content of the other coins was reduced. In 1962, cupronickel replaced silver in the 25-öre and 50-öre coins. In 1968, the 2 kronor switched to cupronickel and the 1-krona switched to cupronickel-clad copper. Nonetheless, all previous mintages of 1- and 2-krona coins are still legal tender, since 1875 and 1876 though 2-krona coins are rarely seen in circulation as they have not been issued since 1971; the 2-krona coins contained 40% silver until 1966, which meant they had been for several years worth much more than two kronor, so most have been bought and melted down by arbitrageurs, the rest are kept by collectors). A new design of 2-krona coins will be issued in 2016. In 1954, 1955 and 1971, five-krona silver coins were produced, with designs similar to contemporary 1- and 2-krona coins. In 1972, a new, smaller 5-krona coin was struck in cupronickel-clad nickel; the current design has been produced since 1976. Five-krona coins minted since 1954 are legal tender but tend to be kept by collectors for their silver content.
In 1971, the 1- and 2-öre, as well as the 2-krona coins ceased production. The size of the 5-öre coin was reduced in 1972. In 1984, production of the five- and 25-öre coins came to an end, followed by that of the 10-öre in 1991. In 1991, aluminium-brass 10-krona coins were introduced. Previous 10-krona coins are not legal tender. In 1991, bronze-coloured 50-öre coins were introduced. Jubilee and commemorative coins have been minted and those since 1897 or are legal tender; the royal motto of the monarch is inscribed on many of the coins. The 5-krona coin was designed in 1974, at a time when there were political efforts to abandon the monarchy, when there was a new young inexperienced king; the monarchy remained. Coins minted before 1974 have the same size, but contain the portrait of King Gustav VI Adolf and his royal motto. On 18 December 2008, the Riksbank announced a proposal to phase out the 50-öre, the final öre c
Government of Sweden
The Government of the Kingdom of Sweden is the national cabinet and the supreme executive authority of Sweden. The short-form name Regeringen is used both in the Fundamental Laws of the Realm and in the vernacular, while the long-form is only used in international treaties; the Government operates as a collegial body with collective responsibility and consists of the Prime Minister—appointed and dismissed by the Speaker of the Riksdag —and other cabinet ministers and dismissed at the sole discretion of the Prime Minister. The Government is responsible for its actions to the Riksdag. Following the adoption of the 1974 Instrument of Government on 1 January 1975—the Government in its present constitutional form was constituted—and in consequence thereof the Swedish Monarch is no longer vested any nominal executive powers at all with respect to the governance of the Realm, but continues to serve as a ceremonial head of state. Instrument of Government, Chapter 12, Article 1; the Instrument of Government —one of the Fundamental Laws of the Realm—sets out the main responsibilities and duties of the Government and how it relates to other organs of the State.
Instrument of Government, Chapter 12, Article 1. Most state administrative authorities, as opposed to local authorities, sorts under the Government, including the Armed Forces, Coast Guard, Customs Service and the Swedish police. While the Judiciary technically sort under the Government in the fiscal sense, Chapter 11 of the Instrument of Government provides safeguards to ensure its independence. In a unique feature of the Swedish constitutional system, individual cabinet ministers do not bear any individual ministerial responsibility for the performance of the agencies within their portfolio; the Government of Sweden is the high contracting party when entering treaties with foreign sovereign states and international organisations, as per 10:1 of the Instrument of Government. In most other parliamentary systems this formal function is vested in the head of state but exercised by ministers in such name. Chapter 6, Article 7 prescribes that laws and ordinances are promulgated by the Government, are subsequently published in the Swedish Code of Statutes.
Following a general election, Speaker of the Riksdag begins to hold talks with the leaders of the parties with representation in the Riksdag, the Speaker nominates a candidate for Prime Minister. The nomination is put to a vote in the chamber. Unless an absolute majority of the members votes "no", the nomination is confirmed, otherwise it is rejected; the Speaker must find a new nominee. This means. After being elected the Prime Minister appoints the cabinet ministers and announces them to the Riksdag; the new Government takes office at a special council held at the Royal Palace before the Monarch, at which the Speaker of the Riksdag formally announces to the Monarch that the Riksdag has elected a new Prime Minister and that the Prime Minister has chosen his cabinet ministers. The Riksdag can cast a vote of no confidence against any single cabinet minister, thus forcing a resignation. To succeed a vote of no confidence must be supported by an absolute majority or it has failed. If a vote of no confidence is cast against the Prime Minister this means the entire government is rejected.
A losing government has one week to call for a general election or else the procedure of nominating a new Prime Minister starts anew. Each appointment of a new Prime Minister is considered to result in a new cabinet, irrespective if the Prime Minister is reappointed or not. However, there is no automatic resignation following a defeat in a general election, so an election does not always result in a new cabinet. Known as the Royal Chancery, the name was changed to the Government Offices on 1 January 1975 with the current Instrument of Government entering into effect; the Instrument of Government mentions in Chapter 7, Article 1 that there is a staff organization supporting the Government known as the Government Offices. The present organizational charter for the Government Offices is found in the ordinance named Förordning med instruktion för Regeringskansliet. Since the issuance of that ordinance in 1996, all the ministries are technically entities within the Government Offices, rather than as separate organisations though they operate as such.
Below follows a short summary of the current structure. Only current ministries and offices are listed below: Government Offices Prime Minister's Office Ministry of Justice Ministry for Foreign Affairs Ministry of Defence Ministry of Health and Social Affairs
The natural environment encompasses all living and non-living things occurring meaning in this case not artificial. The term is most applied to the Earth or some parts of Earth; this environment encompasses the interaction of all living species, climate and natural resources that affect human survival and economic activity. The concept of the natural environment can be distinguished as components: Complete ecological units that function as natural systems without massive civilized human intervention, including all vegetation, soil, rocks and natural phenomena that occur within their boundaries and their nature. Universal natural resources and physical phenomena that lack clear-cut boundaries, such as air and climate, as well as energy, electric charge, magnetism, not originating from civilized human actions. In contrast to the natural environment is the built environment. In such areas where man has fundamentally transformed landscapes such as urban settings and agricultural land conversion, the natural environment is modified into a simplified human environment.
Acts which seem less extreme, such as building a mud hut or a photovoltaic system in the desert, the modified environment becomes an artificial one. Though many animals build things to provide a better environment for themselves, they are not human, hence beaver dams, the works of Mound-building termites, are thought of as natural. People find natural environments on Earth, naturalness varies in a continuum, from 100% natural in one extreme to 0% natural in the other. More we can consider the different aspects or components of an environment, see that their degree of naturalness is not uniform. If, for instance, in an agricultural field, the mineralogic composition and the structure of its soil are similar to those of an undisturbed forest soil, but the structure is quite different. Natural environment is used as a synonym for habitat. For instance, when we say that the natural environment of giraffes is the savanna. Earth science recognizes 4 spheres, the lithosphere, the hydrosphere, the atmosphere, the biosphere as correspondent to rocks, water and life respectively.
Some scientists include, as part of the spheres of the Earth, the cryosphere as a distinct portion of the hydrosphere, as well as the pedosphere as an active and intermixed sphere. Earth science, is an all-embracing term for the sciences related to the planet Earth. There are four major disciplines in earth sciences, namely geography, geology and geodesy; these major disciplines use physics, biology and mathematics to build a qualitative and quantitative understanding of the principal areas or spheres of Earth. The Earth's crust, or lithosphere, is the outermost solid surface of the planet and is chemically and mechanically different from underlying mantle, it has been generated by igneous processes in which magma cools and solidifies to form solid rock. Beneath the lithosphere lies the mantle, heated by the decay of radioactive elements; the mantle though solid is in a state of rheic convection. This convection process causes the lithospheric plates to move, albeit slowly; the resulting process is known as plate tectonics.
Volcanoes result from the melting of subducted crust material or of rising mantle at mid-ocean ridges and mantle plumes. Most water is found in another natural kind of body of water. An ocean is a major body of saline water, a component of the hydrosphere. 71% of the Earth's surface is covered by ocean, a continuous body of water, customarily divided into several principal oceans and smaller seas. More than half of this area is over 3,000 meters deep. Average oceanic salinity is around 35 parts per thousand, nearly all seawater has a salinity in the range of 30 to 38 ppt. Though recognized as several'separate' oceans, these waters comprise one global, interconnected body of salt water referred to as the World Ocean or global ocean; the deep seabeds are more than half the Earth's surface, are among the least-modified natural environments. The major oceanic divisions are defined in part by the continents, various archipelagos, other criteria: these divisions are the Pacific Ocean, the Atlantic Ocean, the Indian Ocean, the Southern Ocean and the Arctic Ocean.
A river is a natural watercourse freshwater, flowing toward an ocean, a lake, a sea or another river. A few rivers flow into the ground and dry up before reaching another body of water; the water in a river is in a channel, made up of a stream bed between banks. In larger rivers there is a wider floodplain shaped by waters over-topping the channel. Flood plains may be wide in relation to the size of the river channel. Rivers are a part of the hydrological cycle. Water within a river is collected from precipitation through surface runoff, groundwater recharge and the release of water stored in glaciers and snowpacks. Small rivers may be termed by several other names, including stream and brook, their current is confined within a stream banks. Streams play an important corridor role in connecting fragmented habitats and thus in conserving biodiversity; the study of streams and waterways in general is known as surface hydrology. A lake is a terrain feature, a body of water, localized to the bottom of basin.
A body of water is considered a lake when it is inland, is not part
