Goat
–
The domestic goat is a subspecies of goat domesticated from the wild goat of southwest Asia and Eastern Europe. The goat is a member of the family Bovidae and is related to the sheep as both are in the goat-antelope subfamily Caprinae. There are over 300 distinct breeds of goat, Goats are one of the oldest domesticated species, and have been used for their milk, meat, hair, and skins over much of the world. In 2011, there were more than 924 million live goats around the globe, according to the UN Food, female goats are referred to as does or nannies, intact males are called bucks or billies, and juveniles of both sexes are called kids. Goat meat from animals is called kid or cabrito, while meat from older animals is known simply as goat or sometimes called chevon. To refer to the male, Old English used bucca until ousted by hegote, hegoote in the late 12th century, nanny goat originated in the 18th century and billy goat in the 19th. Goats are among the earliest animals domesticated by humans, the most recent genetic analysis confirms the archaeological evidence that the wild Bezoar ibex of the Zagros Mountains is the likely original ancestor of probably all domestic goats today. The earliest remnants of domesticated goats dating 10,000 years before present are found in Ganj Dareh in Iran. Goat remains have been found at sites in Jericho, Choga Mami Djeitun and Çayönü. Studies of DNA evidence suggests 10,000 years BP as the domestication date, historically, goat hide has been used for water and wine bottles in both traveling and transporting wine for sale. It has also used to produce parchment. Goats are considered small livestock animals, compared to animals such as cattle, camels and horses, but larger than microlivestock such as poultry, rabbits, cavies. Each recognized breed of goats has specific weight ranges, which vary from over 140 kg for bucks of larger breeds such as the Boer, within each breed, different strains or bloodlines may have different recognized sizes. At the bottom of the range are miniature breeds such as the African Pygmy. Most goats naturally have two horns, of various shapes and sizes depending on the breed, Goats have horns unless they are polled or the horns have been removed, typically soon after birth. There have been incidents of polycerate goats, although this is a genetic rarity thought to be inherited, the horns are most typically removed in commercial dairy goat herds, to reduce the injuries to humans and other goats. Unlike cattle, goats have not been bred to be reliably polled, as the genes determining sex. Breeding together two genetically polled goats results in a number of intersex individuals among the offspring, which are typically sterile

Chinese zodiac
–
The Chinese zodiac is a classification scheme that assigns an animal and its reputed attributes to each year in a repeating 12-year cycle. The 12-year cycle is an approximation to the 11. 86-year orbital period of Jupiter, nevertheless, there are major differences, the Chinese 12-part cycle corresponds to years, rather than months. The Chinese zodiac is represented by 12 animals, whereas some of the signs in the Western zodiac are not animals, the animals of the Chinese zodiac are not associated with constellations spanned by the ecliptic plane. The zodiac traditionally begins with the sign of the Rat, the following are the twelve zodiac signs in order and their characteristics. It is a misconception that the animals assigned by year are the only signs. In fact, there are also animal signs assigned by month, by day, while a person might appear to be a Dragon because they were born in the year of the Dragon, they might also be a Snake internally, an Ox truly, and a Goat secretively. A conflict between a persons zodiac sign and how they live is known as tai sui or kai sui, within the Four Pillars, the year is the pillar representing information about the persons family background and society or relationship with their grandparents. The persons age can also be deduced from the sign of the person, the current sign of the year. For example, a person who is a Tiger is either 12,24,36 or 48 years old in 2010, in 2011, the year of the Rabbit, that person is one year older. The following table shows the 60-year cycle matched up to the Western calendar for the years 1924–2043, the sexagenary cycle begins at lichun about February 4 according to some astrological sources. Within the Four Pillars, the month is the pillar representing information about the parents or childhood. Many Chinese astrologers consider the month pillar to be the most important one in determining the circumstances of ones adult life, the 12 animals are also linked to traditional Chinese agricultural calendar, which runs alongside the better known lunar calendar. Instead of months, this calendar is divided into 24 two week segments known as Solar Terms, each animal is linked to two of these solar terms for a period similar to the Western month. Again unlike the cycle of the years, which begins with the Rat. Around summer days are longer than days, because it occurs differences of perihelion and aphelion. As each sign is linked to a month of the solar year, each of the elements is also linked to a season, and the element that shares a season with a sign is known as that signs fixed element. In other words, that element is believed to some of its characteristics to the sign concerned. The fixed element of each sign applies also to the year and hour signs and it is important to note that the fixed element is separate from the cycle of elements which interact with the signs in the 60-year cycle

Caprinae
–
Subfamily Caprinae is part of the ruminant family Bovidae, consisting of mostly medium-sized bovids. A member of this subfamily is called a caprine, within this subfamily Caprinae, a prominent tribe Caprini includes sheep, goat, and ibex. Some earlier taxonomies considered Caprinae a separate family called Capridae, but now it is considered a subfamily within the Bovidae family. The European mouflon is thought to be the ancestor of the domestic sheep. Many species have become extinct since the last ice age, probably largely because of human interaction, of the survivors, Five are classified as endangered, Eight as vulnerable, Seven as of concern and needing conservation measures, but at lower risk, and Seven species are secure. Members of the group vary considerably in size, from just over 1 m long for a full-grown grey goral, to almost 2.5 m long for a musk ox, musk oxen in captivity have reached over 650 kg. The resource-defenders are the primitive group, they tend to be smaller in size, dark in colour, males and females fairly alike, have long, tassellated ears, long manes. They tend to be larger, highly social, and rather than mark territory with scent glands, no sharp line divides the groups, but a continuum varies from the serows at one end of the spectrum to sheep, true goats, and musk oxen at the other. The goat-antelope, or caprid, group is known from as early as the Miocene, when members of the group resembled the modern serow in their general body form

Chinese culture
–
Chinese culture is one of the worlds oldest cultures, tracing back to thousands of years ago. The area in which the culture is dominant covers a geographical region in eastern Asia with customs. Important components of Chinese culture include ceramics, architecture, music, literature, martial arts, cuisine, visual arts, philosophy, there are 56 officially labelled ethnic groups in China. In terms of numbers however, Han Chinese is by far the largest group, throughout history, many groups have merged into neighboring ethnicities or disappeared. At the same time, many within the Han identity have maintained distinct linguistic, the term Zhonghua Minzu has been used to describe the notion of Chinese nationalism in general. Much of the traditional identity within the community has to do with distinguishing the family name and they were located on the Yellow and Yangtze River. Traditional Chinese Culture covers large geographical territories, where region is usually divided into distinct sub-cultures. Each region is represented by three ancestral items. For example, Guangdong is represented by chenpi, aged ginger, others include ancient cities like Linan, which include tea leaf, bamboo shoot trunk, and hickory nut. Such distinctions give rise to the old Chinese proverb, 十里不同風, 百里不同俗/十里不同风, 百里不同俗, literally the praxis vary within ten li, since the Three Sovereigns and Five Emperors period, some form of Chinese monarch has been the main ruler above all. Different periods of history have different names for the various positions within society, conceptually each imperial or feudal period is similar, with the government and military officials ranking high in the hierarchy, and the rest of the population under regular Chinese law. From the late Zhou Dynasty onwards, traditional Chinese society was organized into a system of socio-economic classes known as the four occupations. However, this system did not cover all groups while the distinctions between all groups became blurred ever since the commercialization of Chinese culture in the Song Dynasty. This led to the creation of a meritocracy, although success was only to males who could afford test preparation. Imperial examinations required applicants to write essays and demonstrate mastery of the Confucian classics and those who passed the highest level of the exam became elite scholar-officials known as jinshi, a highly esteemed socio-economic position. A major mythological structure developed around the topic of the mythology of the imperial exams, trades and crafts were usually taught by a shifu. The female historian Ban Zhao wrote the Lessons for Women in the Han Dynasty and outlined the four women must abide to, while scholars such as Zhu Xi. Chinese marriage and Taoist sexual practices are some of the rituals, most social values are derived from Confucianism and Taoism

Japan
–
Japan is a sovereign island nation in Eastern Asia. Located in the Pacific Ocean, it lies off the eastern coast of the Asia Mainland and stretches from the Sea of Okhotsk in the north to the East China Sea, the kanji that make up Japans name mean sun origin. 日 can be read as ni and means sun while 本 can be read as hon, or pon, Japan is often referred to by the famous epithet Land of the Rising Sun in reference to its Japanese name. Japan is an archipelago consisting of about 6,852 islands. The four largest are Honshu, Hokkaido, Kyushu and Shikoku, the country is divided into 47 prefectures in eight regions. Hokkaido being the northernmost prefecture and Okinawa being the southernmost one, the population of 127 million is the worlds tenth largest. Japanese people make up 98. 5% of Japans total population, approximately 9.1 million people live in the city of Tokyo, the capital of Japan. Archaeological research indicates that Japan was inhabited as early as the Upper Paleolithic period, the first written mention of Japan is in Chinese history texts from the 1st century AD. Influence from other regions, mainly China, followed by periods of isolation, from the 12th century until 1868, Japan was ruled by successive feudal military shoguns who ruled in the name of the Emperor. Japan entered into a period of isolation in the early 17th century. The Second Sino-Japanese War of 1937 expanded into part of World War II in 1941, which came to an end in 1945 following the bombings of Hiroshima and Nagasaki. Japan is a member of the UN, the OECD, the G7, the G8, the country has the worlds third-largest economy by nominal GDP and the worlds fourth-largest economy by purchasing power parity. It is also the worlds fourth-largest exporter and fourth-largest importer, although Japan has officially renounced its right to declare war, it maintains a modern military with the worlds eighth-largest military budget, used for self-defense and peacekeeping roles. Japan is a country with a very high standard of living. Its population enjoys the highest life expectancy and the third lowest infant mortality rate in the world, in ancient China, Japan was called Wo 倭. It was mentioned in the third century Chinese historical text Records of the Three Kingdoms in the section for the Wei kingdom, Wa became disliked because it has the connotation of the character 矮, meaning dwarf. The 倭 kanji has been replaced with the homophone Wa, meaning harmony, the Japanese word for Japan is 日本, which is pronounced Nippon or Nihon and literally means the origin of the sun. The earliest record of the name Nihon appears in the Chinese historical records of the Tang dynasty, at the start of the seventh century, a delegation from Japan introduced their country as Nihon

Korea
–
Korea is a historical state in East Asia, since 1945 divided into two distinct sovereign states, North Korea and South Korea. Located on the Korean Peninsula, Korea is bordered by China to the northwest and it is separated from Japan to the east by the Korea Strait and the Sea of Japan. Korea emerged as a political entity after centuries of conflict among the Three Kingdoms of Korea. Later Silla divided into three states during the Later Three Kingdoms period. Goryeo, which had succeeded Goguryeo, defeated the two states and united the Korean Peninsula. Around the same time, Balhae collapsed and its last crown prince fled south to Goryeo, Goryeo, whose name developed into the modern exonym Korea, was a highly cultured state that created the worlds first metal movable type in 1234. However, multiple invasions by the Mongol Yuan Dynasty during the 13th century greatly weakened the nation, following the Yuan Dynastys collapse, severe political strife followed, and Goryeo eventually fell to a coup led by General Yi Seong-gye, who established Joseon in 1388. The first 200 years of Joseon were marked by peace and saw the creation of the Korean alphabet by Sejong the Great in the 14th century. During the later part of the dynasty, however, Koreas isolationist policy earned it the Western nickname of the Hermit Kingdom, by the late 19th century, the country became the object of imperial design by the Empire of Japan. Despite attempts at modernization by the Korean Empire, in 1910 Korea was annexed by Japan and these circumstances soon became the basis for the division of Korea by the two superpowers, exacerbated by their incapability to agree on the terms of Korean independence. To date, both continue to compete with each other as the sole legitimate government of all of Korea. Korea is the spelling of Corea, a name attested in English as early as 1614. It is a derived from Cauli, Marco Polos transcription of the Chinese 高麗. This was the Hanja for the Korean kingdom of Goryeo or Koryŏ, Goryeos name was a continuation of the earlier Goguryeo or Koguryŏ, the northernmost of the Samguk, which was officially known by the shortened form Goryeo after the 5th-century reign of King Jangsu. The original name was a combination of the go with the name of a local Yemaek tribe. The name Korea is now used in English contexts by both North and South Korea. In South Korea, Korea as a whole is referred to as Hanguk, the name references the Samhan—Ma, Jin, and Byeon—who preceded the Three Kingdoms in the southern and central end of the peninsula during the 1st centuries BC and AD. It has been linked with the title khan used by the nomads of Manchuria

Mongolia /mɒŋˈɡoʊliə/ is a landlocked unitary sovereign state in East Asia. Its area is equivalent with the historical territory of Outer Mongolia. It is sandwiched between China to the south and Russia to the north, while it does not share a border with Kazakhstan, Mongolia is separated from it by only 36.76 kilometers. At 1,564,116 square kilometers, Mongolia is the 18th largest and it is also the worlds second-largest landlocked country behind Kazakhstan and the largest landlocked country that does not border a closed sea. The country contains very little land, as much of its area is covered by grassy steppe, with mountains to the north and west. Ulaanbaatar, the capital and largest city, is home to about 45% of the countrys population, approximately 30% of the population is nomadic or semi-nomadic, horse culture is still integral. The majority of its population are Buddhists, the non-religious population is the second largest group. Islam is the dominant religion among ethnic Kazakhs, the majority of the states citizens are of Mongol ethnicity, although Kazakhs, Tuvans, and other minorities also live in the country, especially in the west. Mongolia joined the World Trade Organization in 1997 and seeks to expand its participation in regional economic, the area of what is now Mongolia has been ruled by various nomadic empires, including the Xiongnu, the Xianbei, the Rouran, the Turkic Khaganate, and others. In 1206, Genghis Khan founded the Mongol Empire, which became the largest contiguous empire in history. His grandson Kublai Khan conquered China to establish the Yuan dynasty, after the collapse of the Yuan, the Mongols retreated to Mongolia and resumed their earlier pattern of factional conflict, except during the era of Dayan Khan and Tumen Zasagt Khan. In the 16th century, Tibetan Buddhism began to spread in Mongolia, being led by the Manchu-founded Qing dynasty. By the early 1900s, almost one-third of the male population were Buddhist monks. After the collapse of the Qing dynasty in 1911, Mongolia declared independence from the Qing dynasty, shortly thereafter, the country came under the control of the Soviet Union, which had aided its independence from China. In 1924, the Mongolian Peoples Republic was declared as a Soviet satellite state, after the anti-Communist revolutions of 1989, Mongolia conducted its own peaceful democratic revolution in early 1990. This led to a multi-party system, a new constitution of 1992, homo erectus inhabited Mongolia from 850,000 years ago. Modern humans reached Mongolia approximately 40,000 years ago during the Upper Paleolithic, the Khoit Tsenkher Cave in Khovd Province shows lively pink, brown, and red ochre paintings of mammoths, lynx, bactrian camels, and ostriches, earning it the nickname the Lascaux of Mongolia. The venus figurines of Malta testify to the level of Upper Paleolithic art in northern Mongolia, the wheeled vehicles found in the burials of the Afanasevans have been dated to before 2200 BC

China, officially the Peoples Republic of China, is a unitary sovereign state in East Asia and the worlds most populous country, with a population of over 1.381 billion. The state is governed by the Communist Party of China and its capital is Beijing, the countrys major urban areas include Shanghai, Guangzhou, Beijing, Chongqing, Shenzhen, Tianjin and Hong Kong. China is a power and a major regional power within Asia. Chinas landscape is vast and diverse, ranging from forest steppes, the Himalaya, Karakoram, Pamir and Tian Shan mountain ranges separate China from much of South and Central Asia. The Yangtze and Yellow Rivers, the third and sixth longest in the world, respectively, Chinas coastline along the Pacific Ocean is 14,500 kilometers long and is bounded by the Bohai, Yellow, East China and South China seas. China emerged as one of the worlds earliest civilizations in the basin of the Yellow River in the North China Plain. For millennia, Chinas political system was based on hereditary monarchies known as dynasties, in 1912, the Republic of China replaced the last dynasty and ruled the Chinese mainland until 1949, when it was defeated by the communist Peoples Liberation Army in the Chinese Civil War. The Communist Party established the Peoples Republic of China in Beijing on 1 October 1949, both the ROC and PRC continue to claim to be the legitimate government of all China, though the latter has more recognition in the world and controls more territory. China had the largest economy in the world for much of the last two years, during which it has seen cycles of prosperity and decline. Since the introduction of reforms in 1978, China has become one of the worlds fastest-growing major economies. As of 2016, it is the worlds second-largest economy by nominal GDP, China is also the worlds largest exporter and second-largest importer of goods. China is a nuclear weapons state and has the worlds largest standing army. The PRC is a member of the United Nations, as it replaced the ROC as a permanent member of the U. N. Security Council in 1971. China is also a member of numerous formal and informal multilateral organizations, including the WTO, APEC, BRICS, the Shanghai Cooperation Organization, the BCIM, the English name China is first attested in Richard Edens 1555 translation of the 1516 journal of the Portuguese explorer Duarte Barbosa. The demonym, that is, the name for the people, Portuguese China is thought to derive from Persian Chīn, and perhaps ultimately from Sanskrit Cīna. Cīna was first used in early Hindu scripture, including the Mahābhārata, there are, however, other suggestions for the derivation of China. The official name of the state is the Peoples Republic of China. The shorter form is China Zhōngguó, from zhōng and guó and it was then applied to the area around Luoyi during the Eastern Zhou and then to Chinas Central Plain before being used as an occasional synonym for the state under the Qing

Written Chinese
–
Written Chinese comprises Chinese characters used to represent the Chinese language. Chinese characters do not constitute an alphabet or a compact syllabary, rather, the writing system is roughly logosyllabic, that is, a character generally represents one syllable of spoken Chinese and may be a word on its own or a part of a polysyllabic word. The characters themselves are composed of parts that may represent physical objects, abstract notions. Literacy requires the memorization of a great many characters, educated Chinese know about 4,000, the large number of Chinese characters has in part led to the adoption of Western alphabets as an auxiliary means of representing Chinese. Various current Chinese characters have been traced back to the late Shang Dynasty about 1200–1050 BC, after a period of variation and evolution, Chinese characters were standardized under the Qin Dynasty. Over the millennia, these characters have evolved into well-developed styles of Chinese calligraphy, as the varieties of Chinese diverged, a situation of diglossia developed, with speakers of mutually unintelligible varieties able to communicate through writing using Classical Chinese. In the early 20th century, Classical Chinese was replaced in this role by written vernacular Chinese, although most other varieties of Chinese are not written, there are traditions of written Cantonese, written Shanghainese and written Hokkien, among others. Written Chinese is not based on an alphabet or a compact syllabary, instead, Chinese characters are glyphs whose components may depict objects or represent abstract notions. Occasionally a character consists of one component, more commonly two or more components are combined to form more complex characters, using a variety of different principles. The best known exposition of Chinese character composition is the Shuowen Jiezi, since Xu Shen did not have access to Chinese characters in their earliest forms, his analysis cannot always be taken as authoritative. Nonetheless, no work has supplanted the Shuowen Jiezi in terms of breadth. According to the Shuowen Jiezi, Chinese characters are developed on six basic principles, the first two principles produce simple characters, known as 文 wén, 象形 xiàngxíng, Pictographs, in which the character is a graphical depiction of the object it denotes. Examples, 人 rén person, 日 rì sun, 木 mù tree/wood, 指事 zhǐshì, Indicatives, or ideographs, in which the character represents an abstract notion. Examples, 上 shàng up, 下 xià down, 三 sān three, the remaining four principles produce complex characters historically called 字 zì. Of these four, two characters from simpler parts, 會意/会意 huìyì, Logical aggregates, in which two or more parts are used for their meaning. This yields a composite meaning, which is applied to the new character. Example, 東/东 dōng east, which represents a sun rising in the trees, example, 晴 qíng clear/fair, which is composed of 日 rì sun, and 青 qīng blue/green, which is used for its pronunciation. In fact, some phonetic complexes were originally simple pictographs that were augmented by the addition of a semantic root

Chinese characters
–
Chinese characters are logograms used in the writing of Chinese and some other Asian languages. In Standard Chinese, and sometimes also in English, they are called hànzì. They have been adapted to write a number of languages including, Japanese, where they are known as kanji, Korean, where they are known as hanja. Collectively, they are known as CJK characters, in English, they are sometimes called Han characters. Chinese characters constitute the oldest continuously used system of writing in the world, Chinese characters number in the tens of thousands, though most of them are minor graphic variants encountered only in historical texts. Studies in China have shown that literacy in written Chinese requires a knowledge of between three and four thousand characters. In Japan,2,136 are taught through secondary school, the characters used in Japan are distinct from those used in China in many respects. There are various national standard lists of characters, forms, in South Korea, when Chinese characters are used they are of the traditional variant and are almost identical to those used in places like Taiwan and Hong Kong. In Old Chinese, most words were monosyllabic and there was a correspondence between characters and words. Rather, a character almost always corresponds to a syllable that is also a morpheme. However, there are a few exceptions to this correspondence, including bisyllabic morphemes. Modern Chinese has many homophones, thus the same syllable may be represented by many characters. A single character may also have a range of meanings, or sometimes quite distinct meanings, cognates in the several varieties of Chinese are generally written with the same character. They typically have similar meanings, but often quite different pronunciations and these foreign adaptations of Chinese pronunciation are known as Sino-Xenic pronunciations, and have been useful in the reconstruction of Middle Chinese. When the script was first used in the late 2nd millennium BC, words of Old Chinese were generally monosyllabic, increasing numbers of polysyllabic words have entered the language from the Western Zhou period to the present day. The process has accelerated over the centuries as phonetic change has increased the number of homophones and it has been estimated that over two thirds of the 3,000 most common words in modern Standard Chinese are polysyllables, the vast majority of those being disyllables. The most common process has been to form compounds of existing words, words have also been created by adding affixes, reduplication and borrowing from other languages. Polysyllabic words are written with one character per syllable

Zodiac
–
The zodiac is an area of the sky centered upon the ecliptic, the apparent path of the Sun across the celestial sphere over the course of the year. The paths of the Moon and visible planets also remain close to the ecliptic, within the belt of the zodiac, in western astrology and astronomy, the zodiac is divided into twelve signs, each sign occupying 30° of celestial longitude. Because the signs are regular, they do not correspond exactly to the boundaries of the twelve constellations after which they are named, the English word zodiac derives from zōdiacus, the Latinized form of the Ancient Greek zōidiakòs kýklos, meaning circle of little animals. Zōidion is the diminutive of zōion, the name reflects the prominence of animals among the twelve signs. The construction of the zodiac is described in Ptolemys vast 2nd century AD work, the term zodiac may also refer to the region of the celestial sphere encompassing the paths of the planets corresponding to the band of about eight arc degrees above and below the ecliptic. The zodiac of a planet is the band that contains the path of that particular body, e. g. the zodiac of the Moon is the band of five degrees above. By extension, the zodiac of the comets may refer to the band encompassing most short-period comets, the division of the ecliptic into the zodiacal signs originates in Babylonian astronomy during the first half of the 1st millennium BC. The zodiac draws on stars in earlier Babylonian star catalogues, such as the MUL. APIN catalogue, around the end of the 5th century BC, Babylonian astronomers divided the ecliptic into twelve equal signs, by analogy to twelve schematic months of thirty days each. Each sign contained thirty degrees of longitude, thus creating the first known celestial coordinate system. Because the division was made into equal arcs, 30° each, in Babylonian astronomical diaries, a planet position was generally given with respect to a zodiacal sign alone, less often in specific degrees within a sign. When the degrees of longitude were given, they were expressed with reference to the 30° of the zodiacal sign, in astronomical ephemerides, the positions of significant astronomical phenomena were computed in sexagesimal fractions of a degree. For daily ephemerides, the positions of a planet were not as important as the astrologically significant dates when the planet crossed from one zodiacal sign to the next. The Babylonian star catalogs entered Greek astronomy in the 4th century BC, Babylonia or Chaldea in the Hellenistic world came to be so identified with astrology that Chaldean wisdom became among Greeks and Romans the synonym of divination through the planets and stars. Hellenistic astrology derived in part from Babylonian and Egyptian astrology, horoscopic astrology first appeared in Ptolemaic Egypt. The Dendera zodiac, a dating to ca.50 BC, is the first known depiction of the classical zodiac of twelve signs. The earliest extant Greek text using the Babylonian division of the zodiac into 12 signs of 30 equal degrees each is the Anaphoricus of Hypsicles of Alexandria. Particularly important in the development of Western horoscopic astrology was the astrologer and astronomer Ptolemy, whose work Tetrabiblos laid the basis of the Western astrological tradition. Under the Greeks, and Ptolemy in particular, the planets, Houses, Ptolemy lived in the 2nd century AD, three centuries after the discovery of the precession of the equinoxes by Hipparchus around 130 BC

Nature
–
Nature, in the broadest sense, is the natural, physical, or material world or universe. Nature can refer to the phenomena of the world. The study of nature is a part of science. Although humans are part of nature, human activity is understood as a separate category from other natural phenomena. The word nature is derived from the Latin word natura, or essential qualities, innate disposition, and in ancient times, literally meant birth. Natura is a Latin translation of the Greek word physis, which related to the intrinsic characteristics that plants, animals. This usage continued during the advent of scientific method in the last several centuries. Within the various uses of the word today, nature often refers to geology, for example, manufactured objects and human interaction generally are not considered part of nature, unless qualified as, for example, human nature or the whole of nature. Depending on the context, the term natural might also be distinguished from the unnatural or the supernatural. Earth is the planet known to support life, and its natural features are the subject of many fields of scientific research. Within the solar system, it is third closest to the sun, it is the largest terrestrial planet and its most prominent climatic features are its two large polar regions, two relatively narrow temperate zones, and a wide equatorial tropical to subtropical region. Precipitation varies widely with location, from several metres of water per year to less than a millimetre,71 percent of the Earths surface is covered by salt-water oceans. The remainder consists of continents and islands, with most of the land in the Northern Hemisphere. Earth has evolved through geological and biological processes that have left traces of the original conditions, the outer surface is divided into several gradually migrating tectonic plates. The interior remains active, with a layer of plastic mantle. This iron core is composed of a solid phase. Convective motion in the core generates electric currents through dynamo action, the atmospheric conditions have been significantly altered from the original conditions by the presence of life-forms, which create an ecological balance that stabilizes the surface conditions. Geology is the science and study of the solid and liquid matter that constitutes the Earth, the geology of an area evolves through time as rock units are deposited and inserted and deformational processes change their shapes and locations
