City
–
A city is a large and permanent human settlement. Cities generally have complex systems for sanitation, utilities, land usage, housing, a big city or metropolis usually has associated suburbs and exurbs. Such cities are associated with metropolitan areas and urban areas. Once a city expands far enough to another city, this region can be deemed a conurbation or megalopolis. Damascus is arguably the oldest city in the world, in terms of population, the largest city proper is Shanghai, while the fastest-growing is Dubai. There is not enough evidence to assert what conditions gave rise to the first cities, some theorists have speculated on what they consider suitable pre-conditions and basic mechanisms that might have been important driving forces. The conventional view holds that cities first formed after the Neolithic revolution, the Neolithic revolution brought agriculture, which made denser human populations possible, thereby supporting city development. The advent of farming encouraged hunter-gatherers to abandon nomadic lifestyles and to settle near others who lived by agricultural production, the increased population density encouraged by farming and the increased output of food per unit of land created conditions that seem more suitable for city-like activities. In his book, Cities and Economic Development, Paul Bairoch takes up position in his argument that agricultural activity appears necessary before true cities can form. According to Vere Gordon Childe, for a settlement to qualify as a city, it must have enough surplus of raw materials to support trade and a relatively large population. To illustrate this point, Bairoch offers an example, Western Europe during the pre-Neolithic, when the cost of transport is taken into account, the figure rises to 200,000 square kilometres. Bairoch noted that this is roughly the size of Great Britain, the urban theorist Jane Jacobs suggests that city formation preceded the birth of agriculture, but this view is not widely accepted. In his book City Economics, Brendan OFlaherty asserts Cities could persist—as they have for thousands of years—only if their advantages offset the disadvantages, OFlaherty illustrates two similar attracting advantages known as increasing returns to scale and economies of scale, which are concepts usually associated with businesses. Their applications are seen in more basic economic systems as well, increasing returns to scale occurs when doubling all inputs more than doubles the output an activity has economies of scale if doubling output less than doubles cost. To offer an example of these concepts, OFlaherty makes use of one of the oldest reasons why cities were built, in this example, the inputs are anything that would be used for protection and the output is the area protected and everything of value contained in it. OFlaherty then asks that we suppose the protected area is square, the advantage is expressed as, O = s 2, where O is the output and s stands for the length of a side. This equation shows that output is proportional to the square of the length of a side, the inputs depend on the length of the perimeter, I =4 s, where I stands for the quantity of inputs. So there are increasing returns to scale, O = I2 /16 and this equation shows that with twice the inputs, you produce quadruple the output

Alabama
–
Alabama is a state in the southeastern region of the United States. It is bordered by Tennessee to the north, Georgia to the east, Florida and the Gulf of Mexico to the south, Alabama is the 30th-most extensive and the 24th-most populous of the U. S. states. At nearly 1,500 miles, Alabama has one of the nations longest navigable inland waterways, Alabama is nicknamed the Yellowhammer State, after the state bird. Alabama is also known as the Heart of Dixie and the Cotton State, the state tree is the longleaf pine, and the state flower is the camellia. The largest city by population is Birmingham, which has long been the most industrialized city, the oldest city is Mobile, founded by French colonists in 1702 as the capital of French Louisiana. From the American Civil War until World War II, Alabama, like many states in the southern U. S. suffered economic hardship, like other southern states, Alabama legislators disenfranchised African Americans and many poor whites at the turn of the century. Following World War II, Alabama grew as the economy changed from one primarily based on agriculture to one with diversified interests. The state economy in the 21st century is based on management, automotive, finance, manufacturing, aerospace, mineral extraction, healthcare, education, retail, in the Alabama language, the word for a person of Alabama lineage is Albaamo. The word Alabama is believed to have come from the Alabama language, the words spelling varies significantly among historical sources. As early as 1702, the French called the tribe the Alibamon, other spellings of the name have included Alibamu, Alabamo, Albama, Alebamon, Alibama, Alibamou, Alabamu, Allibamou. Sources disagree on the words meaning, some scholars suggest the word comes from the Choctaw alba and amo. The meaning may have been clearers of the thicket or herb gatherers, the state has numerous place names of Native American origin. However, there are no correspondingly similar words in the Alabama language, an 1842 article in the Jacksonville Republican proposed it meant Here We Rest. This notion was popularized in the 1850s through the writings of Alexander Beaufort Meek, experts in the Muskogean languages have not found any evidence to support such a translation. Indigenous peoples of varying cultures lived in the area for thousands of years before the advent of European colonization, trade with the northeastern tribes by the Ohio River began during the Burial Mound Period and continued until European contact. The agrarian Mississippian culture covered most of the state from 1000 to 1600 AD, with one of its major centers built at what is now the Moundville Archaeological Site in Moundville, Alabama. This is the second-largest complex of the classic Middle Mississippian era, after Cahokia in present-day Illinois, Analysis of artifacts from archaeological excavations at Moundville were the basis of scholars formulating the characteristics of the Southeastern Ceremonial Complex. Contrary to popular belief, the SECC appears to have no links to Mesoamerican culture

Baldwin County, Alabama
–
Baldwin County is a county of the U. S. state of Alabama. According to the 2015 estimates from the U. S. Census Bureau, the county seat is Bay Minette. The county is named in honor of Senator Abraham Baldwin, though he never lived in what is now Alabama, the U. S. federal government designates Baldwin County as the Daphne-Fairhope-Foley, AL Metropolitan Statistical Area. It is the largest county in Alabama by area and is located on the side of Mobile Bay. Baldwin County was established on December 21,1809, ten years before Alabama became a state, previously, the county had been a part of the Mississippi Territory until 1817, when the area was included in the separate Alabama Territory. Statehood was gained by Alabama in 1819, there have been numerous border changes to the county as population grew and other counties were formed. Numerous armies have invaded during the Revolutionary War, War of 1812, in the first days of Baldwin County, the town of McIntosh Bluff on the Tombigbee River was the county seat. The county seat was transferred to the town of Blakeley in 1810, in 1900, by an act of the legislature of Alabama, the county seat was authorized for relocation to the city of Bay Minette, however, the city of Daphne resisted this relocation. To achieve the relocation, the men of Bay Minette devised a scheme and they fabricated a murder to lure the Sheriff and his deputy out of the Daphne. A New Deal mural, completed by WPA artists during the Great Depression and it hangs in the Bay Minette United States post office. Due to its proximity to the Gulf of Mexico, Baldwin County frequently endures tropical weather systems, including hurricanes. According to the U. S. Census Bureau, the county has an area of 2,027 square miles. It is the largest county by area in Alabama and the 12th-largest county east of the Mississippi River and it is larger than the US state of Rhode Island. As of April 2007, only two areas in Alabama have received what is the highest environmental status in the state. A portion of Wolf Bay and 42 miles of the Tensaw River in northern Baldwin County have received the designation, officials believe the pristine water will become an important eco-tourism destination. Bon Secour National Wildlife Refuge Interstate 10 Interstate 65 U. S. Highway 31 U. S. Highway 90 U. S, considerable military airspace overlies much of the county and adjacent bay and coastal waters. Commercial, scheduled service is from Mobile Regional Airport or Pensacola International Airport, the population density was 110 people per square mile. There were 104,061 housing units at a density of 54 per square mile

ZIP Code
–
ZIP Codes are a system of postal codes used by the United States Postal Service since 1963. The term ZIP, an acronym for Zone Improvement Plan, was chosen to suggest that the travels more efficiently, and therefore more quickly. The basic format consists of five numerical digits, an extended ZIP+4 code, introduced in 1983, includes the five digits of the ZIP Code, a hyphen, and four additional digits that determine a more specific location within a given ZIP Code. The term ZIP Code was originally registered as a servicemark by the U. S. Postal Service, USPS style for ZIP is all caps and the c in code is also capitalized, although style sheets for some publications use sentence case or lowercase. The early history and context of postal codes began with postal district/zone numbers, the United States Post Office Department implemented postal zones for numerous large cities in 1943. For example, Mr. John Smith 3256 Epiphenomenal Avenue Minneapolis 16, by the early 1960s a more organized system was needed, and on July 1,1963, non-mandatory five-digit ZIP Codes were introduced nationwide. Three months later, on October 1,1963, the U. S, an earlier list in June had proposed capitalized abbreviations ranging from two to five letters. The abbreviations have remained unchanged, with one exception, according to the historian of the U. S. Robert Moon, an employee of the post office, is considered the father of the ZIP Code, he submitted his proposal in 1944 while working as a postal inspector. The post office gives credit to Moon only for the first three digits of the ZIP Code, which describe the sectional center facility or sec center, an SCF is a central mail processing facility with those three digits. The SCF sorts mail to all post offices with those first three digits in their ZIP Codes, the mail is sorted according to the final two digits of the ZIP Code and sent to the corresponding post offices in the early morning. Sectional centers do not deliver mail and are not open to the public, Mail picked up at post offices is sent to their own SCF in the afternoon, where the mail is sorted overnight. The United States Post Office used a character, which it called Mr. ZIP. He was often depicted with a such as USE ZIP CODE in the selvage of panes of stamps or on labels contained in, or the covers of. In 1983, the U. S. Postal Service introduced an expanded ZIP Code system that it called ZIP+4, often called plus-four codes, add-on codes, or add ons. But initial attempts to promote use of the new format met with public resistance. For Post Office Boxes, the rule is that each box has its own ZIP+4 code. However, there is no rule, so the ZIP+4 Code must be looked up individually for each box. It is common to use add-on code 9998 for mail addressed to the postmaster,9999 for general delivery, for a unique ZIP Code, the add-on code is typically 0001

Florida
–
Florida /ˈflɒrᵻdə/ is a state located in the southeastern region of the United States. It is bordered to the west by the Gulf of Mexico, to the north by Alabama and Georgia, to the east by the Atlantic Ocean, Florida is the 22nd-most extensive, the 3rd-most populous, and the 8th-most densely populated of the U. S. states. Jacksonville is the most populous municipality in the state and is the largest city by area in the contiguous United States, the Miami metropolitan area is Floridas most populous urban area. The city of Tallahassee is the state capital, much of the state is at or near sea level and is characterized by sedimentary soil. The climate varies from subtropical in the north to tropical in the south, the American alligator, American crocodile, Florida panther, and manatee can be found in the Everglades National Park. It was a location of the Seminole Wars against the Native Americans. Today, Florida is distinctive for its large Cuban expatriate community and high population growth, the states economy relies mainly on tourism, agriculture, and transportation, which developed in the late 19th century. Florida is also renowned for amusement parks, orange crops, the Kennedy Space Center, Florida has attracted many writers such as Marjorie Kinnan Rawlings, Ernest Hemingway and Tennessee Williams, and continues to attract celebrities and athletes. It is internationally known for golf, tennis, auto racing, by the 16th century, the earliest time for which there is a historical record, major Native American groups included the Apalachee, the Timucua, the Ais, the Tocobaga, the Calusa and the Tequesta. Florida was the first part of the continental United States to be visited and settled by Europeans, the earliest known European explorers came with the Spanish conquistador Juan Ponce de León. Ponce de León spotted and landed on the peninsula on April 2,1513 and he named the region La Florida. The story that he was searching for the Fountain of Youth is a myth, in May 1539, Conquistador Hernando de Soto skirted the coast of Florida, searching for a deep harbor to land. He described seeing a wall of red mangroves spread mile after mile, some reaching as high as 70 feet. Very soon, many smokes appeared along the whole coast, billowing against the sky, the Spanish introduced Christianity, cattle, horses, sheep, the Spanish language, and more to Florida. Both the Spanish and French established settlements in Florida, with varying degrees of success, in 1559, Don Tristán de Luna y Arellano established a settlement at present-day Pensacola, making it the first attempted settlement in Florida, but it was abandoned by 1561. Spain maintained tenuous control over the region by converting the tribes to Christianity. The area of Spanish Florida diminished with the establishment of English settlements to the north, the English attacked St. Augustine, burning the city and its cathedral to the ground several times. Florida attracted numerous Africans and African-Americans from adjacent British colonies who sought freedom from slavery, in 1738, Governor Manuel de Montiano established Fort Gracia Real de Santa Teresa de Mose near St

Marriage
–
The definition of marriage varies according to different cultures, but it is principally an institution in which interpersonal relationships, usually sexual, are acknowledged. In some cultures, marriage is recommended or considered to be compulsory before pursuing any sexual activity, when defined broadly, marriage is considered a cultural universal. Individuals may marry for several reasons, including legal, social, libidinal, emotional, financial, spiritual, whom they marry may be influenced by socially determined rules of incest, prescriptive marriage rules, parental choice and individual desire. In some areas of the world, arranged marriage, child marriage, polygamy, conversely, such practices may be outlawed and penalized in parts of the world out of concerns for womens rights and because of international law. These trends coincide with the human rights movement. Marriage can be recognized by a state, an organization, an authority, a tribal group. It is often viewed as a contract, Marriages can be performed in a secular civil ceremony or in a religious setting via a wedding ceremony. The act of marriage usually creates normative or legal obligations between the individuals involved, and any offspring they may produce, some cultures allow the dissolution of marriage through divorce or annulment. In some areas, child marriages and polygamy may occur in spite of laws against the practice. For example, the number of marriages in Europe decreased by 30% from 1975 to 2005 and these changes have occurred primarily in Western countries. The word marriage derives from Middle English mariage, which first appears in 1250–1300 CE and this in turn is derived from Old French, marier, and ultimately Latin, marītāre, meaning to provide with a husband or wife and marītāri meaning to get married. The adjective marīt-us -a, -um meaning matrimonial or nuptial could also be used in the form as a noun for husband. Anthropologists have proposed several competing definitions of marriage in an attempt to encompass the wide variety of marital practices observed across cultures, even within Western culture, definitions of marriage have careened from one extreme to another and everywhere in between. The anthropological handbook Notes and Queries defined marriage as a union between a man and a such that children born to the woman are the recognized legitimate offspring of both partners. In recognition of a practice by the Nuer people of Sudan allowing women to act as a husband in certain circumstances, Kathleen Gough suggested modifying this to a woman, none of these men had legal rights to the womans child. Economic anthropologist Duran Bell has criticized the definition on the basis that some societies do not require marriage for legitimacy. He argued that a definition of marriage is circular in societies where illegitimacy has no other legal or social implications for a child other than the mother being unmarried. In 1955 article in Man, Leach argued that no one definition of marriage applied to all cultures and he offered a list of ten rights associated with marriage, including sexual monopoly and rights with respect to children, with specific rights differing across cultures

Ferris wheel
–
Some of the largest modern Ferris wheels have cars mounted on the outside of the rim, with electric motors to independently rotate each car to keep it upright. These wheels are sometimes referred to as wheels and their cars referred to as capsules. The original Ferris Wheel was designed and constructed by George Washington Gale Ferris Jr. as a landmark for the 1893 Worlds Columbian Exposition in Chicago. The generic term Ferris wheel is now used for all such structures, since the original 1893 Chicago Ferris wheel there have been nine worlds tallest-ever Ferris wheels. The current record holder is the 167. 6-metre High Roller in Las Vegas, US, pleasure wheels, whose passengers rode in chairs suspended from large wooden rings turned by strong men, may have originated in 17th-century Bulgaria. A Frenchman, Antonio Manguino, introduced the idea to America in 1848, a much earlier description of a Ferris-type wheel can be seen in The Death of Arthur, a volume of the Vulgate Cycle dating from around 1220. The text describes King Arthur in a dream being approached by Fortuna, the following year he was granted the first U. S. patent for a Roundabout. George Washington Gale Ferris Jr. rode on Somers wheel in Atlantic City prior to designing his wheel for the Worlds Columbian Exposition, the original Ferris Wheel, sometimes also referred to as the Chicago Wheel, was designed and constructed by George Washington Gale Ferris Jr. With a height of 80.4 metres it was the largest attraction at the Worlds Columbian Exposition in Chicago, Illinois and it was intended to rival the 324-metre Eiffel Tower, the centerpiece of the 1889 Paris Exposition. Ferris was a graduate of Rensselaer Polytechnic Institute and a Pittsburgh, Pennsylvania and he began his career in the railroad industry and then pursued an interest in bridge building. Ferris understood the growing need for steel and founded G. W. G. Ferris & Co. in Pittsburgh, a firm that tested and inspected metals for railroads, the wheel rotated on a 71-ton,45. There were 36 cars, each fitted with 40 revolving chairs and able to accommodate up to 60 people, the Exposition ended in October 1893, and the wheel closed in April 1894 and was dismantled and stored until the following year. It was then rebuilt on Chicagos North Side, near Lincoln Park and this prompted William D. Boyce, then a local resident, to file a Circuit Court action against the owners of the wheel to have it removed, but without success. The Wiener Riesenrad is an example of nineteenth-century Ferris wheels. A demolition permit for the Riesenrad was issued in 1916, but due to a lack of funds with which to carry out the destruction, following the demolition of the 100-metre Grande Roue de Paris in 1920, the Riesenrad became the worlds tallest extant Ferris wheel. Still in operation today, it is one of Viennas most popular tourist attractions, chronology of worlds tallest-ever wheels 1893, the original Ferris Wheel was 80.4 metres tall. Built for the Worlds Columbian Exposition in Chicago, Illinois, it was moved to St. Louis, Missouri, in 1904 for the Louisiana Purchase Exposition, and demolished there in 1906

Dolphin
–
Dolphins are a widely distributed and diverse group of aquatic mammals. They are a grouping within the order Cetacea, excluding whales and porpoises. The dolphins comprise the extant families Delphinidae, Platanistidae, Iniidae, and Pontoporiidae, there are 40 extant species of dolphins. Dolphins, alongside other cetaceans, belong to the clade Cetartiodactyla with even-toed ungulates and their closest living relatives are the hippopotamuses, having diverged about 40 million years ago. Dolphins range in size from the 1.7 m long and 50 kg Mauis dolphin to the 9.5 m and 10 t killer whale, several species exhibit sexual dimorphism, in that the males are larger than females. They have streamlined bodies and two limbs that are modified into flippers, though not quite as flexible as seals, some dolphins can travel at 55.5 km/h. Dolphins use their conical shaped teeth to capture fast moving prey and they have well-developed hearing which is adapted for both air and water and is so well developed that some can survive even if they are blind. Some species are adapted for diving to great depths. They have a layer of fat, or blubber, under the skin to keep warm in the cold water, although dolphins are widespread, most species prefer the warmer waters of the tropic zones, but some, like the right whale dolphin, prefer colder climates. Dolphins feed largely on fish and squid, but a few, like the killer whale, feed on large mammals, male dolphins typically mate with multiple females every year, but females only mate every two to three years. Calves are typically born in the spring and summer months and females bear all the responsibility for raising them, mothers of some species fast and nurse their young for a relatively long period of time. Dolphins produce a variety of vocalizations, usually in the form of clicks, Dolphins are sometimes hunted in places like Japan, in an activity known as dolphin drive hunting. Besides drive hunting, they face threats from bycatch, habitat loss. Dolphins have been depicted in cultures worldwide. Dolphins occasionally feature in literature and film, as in the film series Free Willy, Dolphins are sometimes kept in captivity and trained to perform tricks, but breeding success has been poor and the animals often die within a few months of capture. The most common dolphins kept are killer whales and bottlenose dolphins, the name is originally from Greek δελφίς, dolphin, which was related to the Greek δελφύς, womb. The animals name can therefore be interpreted as meaning a fish with a womb, the name was transmitted via the Latin delphinus, which in Medieval Latin became dolfinus and in Old French daulphin, which reintroduced the ph into the word. The term mereswine has also historically been used, the term dolphin can be used to refer to, under the parvorder Odontoceti, all the species in the family Delphinidae and the river dolphin families Iniidae, Pontoporiidae, Lipotidae and Platanistidae

Golf
–
Golf is a club and ball sport in which players use various clubs to hit balls into a series of holes on a course in as few strokes as possible. Golf, unlike most ball games, cannot and does not utilize a standardized playing area, the game is played on a course with an arranged progression of 18 holes. Each hole on the course must contain a tee box to start from, there are other standard forms of terrain in between, such as the fairway, rough, sand traps, and hazards but each hole on a course is unique in its specific layout and arrangement. Stroke play is the most commonly seen format at all levels, while the modern game of golf originated in 15th-century Scotland, the games ancient origins are unclear and much debated. Some historians trace the sport back to the Roman game of paganica, one theory asserts that paganica spread throughout Europe as the Romans conquered most of the continent, during the first century BC, and eventually evolved into the modern game. Others cite chuiwan as the progenitor, a Chinese game played between the eighth and 14th centuries, the game is thought to have been introduced into Europe during the Middle Ages. Another early game that resembled modern golf was known as cambuca in England, the Persian game chaugán is another possible ancient origin. In addition, kolven was played annually in Loenen, Netherlands, beginning in 1297, to commemorate the capture of the assassin of Floris V, a year earlier. The modern game originated in Scotland, where the first written record of golf is James IIs banning of the game in 1457, as an unwelcome distraction to learning archery. James IV lifted the ban in 1502 when he became a golfer himself, with golf clubs first recorded in 1503-1504, to many golfers, the Old Course at St Andrews, a links course dating to before 1574, is considered to be a site of pilgrimage. In 1764, the standard 18-hole golf course was created at St Andrews when members modified the course from 22 to 18 holes. Golf is documented as being played on Musselburgh Links, East Lothian, Scotland as early as 2 March 1672, which is certified as the oldest golf course in the world by Guinness World Records. The oldest surviving rules of golf were compiled in March 1744 for the Company of Gentlemen Golfers, later renamed The Honourable Company of Edinburgh Golfers, Andrews Golf Club in Yonkers, New York. The levels of grass are varied to increase difficulty, or to allow for putting in the case of the green, while many holes are designed with a direct line-of-sight from the teeing area to the green, some holes may bend either to the left or to the right. This is commonly called a dogleg, in reference to a dogs knee, the hole is called a dogleg left if the hole angles leftwards and dogleg right if it bends right. Sometimes, a holes direction may bend twice, this is called a double dogleg, a regular golf course consists of 18 holes, but nine-hole courses are common and can be played twice through for a full round of 18 holes. Early Scottish golf courses were laid out on links land. This gave rise to the golf links, particularly applied to seaside courses

Gulf of Mexico
–
The Gulf of Mexico is an ocean basin largely surrounded by the North American continent. It is bounded on the northeast, north and northwest by the Gulf Coast of the United States, on the southwest and south by Mexico, and on the southeast by Cuba. The U. S. states of Alabama, Florida, Louisiana, Mississippi and Texas border the Gulf on the north, Atlantic and Pacific coasts, or sometimes the south coast, in juxtaposition to the Great Lakes region being the north coast. One of the seven main areas is the Gulf of Mexico basin. The Gulf of Mexico formed approximately 300 million years ago as a result of plate tectonics, the Gulfs basin is roughly oval and is approximately 810 nautical miles wide and floored by sedimentary rocks and recent sediments. It is connected to part of the Atlantic Ocean through the Florida Straits between the U. S. and Cuba, and with the Caribbean Sea via the Yucatan Channel between Mexico and Cuba, with the narrow connection to the Atlantic, the Gulf experiences very small tidal ranges. The size of the Gulf basin is approximately 1.6 million km2, almost half of the basin is shallow continental shelf waters. The basin contains a volume of roughly 2,500 quadrillion liters, the consensus among geologists who have studied the geology of the Gulf of Mexico, is that prior to the Late Triassic, the Gulf of Mexico did not exist. It was created by the collision of plates that formed Pangea. As interpreted by Roy Van Arsdale and Randel T. Cox, geologists and other Earth scientists agree in general that the present Gulf of Mexico basin originated in Late Triassic time as the result of rifting within Pangea. The rifting was associated with zones of weakness within Pangea, including sutures where the Laurentia, South American, first, there was a Late Triassic-Early Jurassic phase of rifting during which rift valleys formed and filled with continental red beds. Second, as rifting progressed through Early and Middle Jurassic time and it was at this time that tectonics first created a connection to the Pacific Ocean across central Mexico and later eastward to the Atlantic Ocean. This flooded the basin created by rifting and crustal thinning to create the Gulf of Mexico. While the Gulf of Mexico was a basin, the subsiding transitional crust was blanketed by the widespread deposition of Louann Salt. Initially, during the Late Jurassic, continued rifting widened the Gulf of Mexico and progressed to the point that sea-floor spreading, at this point, sufficient circulation with the Atlantic Ocean was established that the deposition of Louann Salt ceased. During the Late Jurassic through Early Cretaceous, the occupied by the Gulf of Mexico experienced a period of cooling. The subsidence was the result of a combination of stretching, cooling. Initially, the combination of stretching and cooling caused about 5–7 km of tectonic subsidence of the central thin transitional

Precipitation
–
In meteorology, precipitation is any product of the condensation of atmospheric water vapor that falls under gravity. The main forms of precipitation include drizzle, rain, sleet, snow, graupel, Precipitation occurs when a portion of the atmosphere becomes saturated with water vapor, so that the water condenses and precipitates. Thus, fog and mist are not precipitation but suspensions, because the vapor does not condense sufficiently to precipitate. Two processes, possibly acting together, can lead to air becoming saturated, Precipitation forms as smaller droplets coalesce via collision with other rain drops or ice crystals within a cloud. Short, intense periods of rain in scattered locations are called showers, moisture that is lifted or otherwise forced to rise over a layer of sub-freezing air at the surface may be condensed into clouds and rain. This process is active when freezing rain is occurring. A stationary front is often present near the area of freezing rain, provided necessary and sufficient atmospheric moisture content, the moisture within the rising air will condense into clouds, namely stratus and cumulonimbus. Eventually, the droplets will grow large enough to form raindrops. Lake-effect snowfall can be locally heavy, thundersnow is possible within a cyclones comma head and within lake effect precipitation bands. In mountainous areas, heavy precipitation is possible where upslope flow is maximized within windward sides of the terrain at elevation, on the leeward side of mountains, desert climates can exist due to the dry air caused by compressional heating. The movement of the trough, or intertropical convergence zone. Precipitation is a component of the water cycle, and is responsible for depositing the fresh water on the planet. Approximately 505,000 cubic kilometres of water falls as precipitation each year,398,000 cubic kilometres of it over the oceans and 107,000 cubic kilometres over land. Given the Earths surface area, that means the globally averaged annual precipitation is 990 millimetres, Climate classification systems such as the Köppen climate classification system use average annual rainfall to help differentiate between differing climate regimes. Precipitation may occur on celestial bodies, e. g. when it gets cold, Mars has precipitation which most likely takes the form of frost. Precipitation is a component of the water cycle, and is responsible for depositing most of the fresh water on the planet. Approximately 505,000 km3 of water falls as precipitation each year,398,000 km3 of it over the oceans, given the Earths surface area, that means the globally averaged annual precipitation is 990 millimetres. Mechanisms of producing precipitation include convective, stratiform, and orographic rainfall, Precipitation can be divided into three categories, based on whether it falls as liquid water, liquid water that freezes on contact with the surface, or ice

Perdido Pass
–
Perdido Pass, separating Alabama Point from Florida Point, is the mouth of the Perdido River. Perdido Pass forms a water passage that connects Perdido Bay with the Gulf of Mexico to the south, a bridge spans Perdido Pass, connecting Alabama Point with Florida Point in Alabama. At the entrance into the Gulf, the 2 rock barriers, the surrounding area is heavily developed, with high-rise condominiums. However, there are nearby beach-front parks, with Gulf State Park on the side of Perdido Pass. The fixed span over Perdido Pass Channel has a clearance of 54 feet, the fixed span over Cotton Bayou Channel has a clearance of 41 feet. The entrance to the pass is protected by a jetty on the west and by a weir and jetty on the east. Numerous sunken wrecks are in the approach to the pass, in October 2006, the controlling depth was 5.2 feet, reaching 8.2 ft at mid-channel, in the entrance channel to the intersection of the east and west channels. A lighted whistle buoy off the marks the approach. The Intracoastal Waterway, in the part of Perdido Bay, is reached from Perdido Pass via a marked channel through Bayou St. John. In May 1982, shoaling to 6 feet was reported in Bayou St. John, an overhead power cable, with a clearance of 59 ft, crosses the channel leading to Terry Cove and Johnson Cove, about 0.4 miles from the State Route 182 fixed bridge. Several small-craft facilities are in the coves and Cotton Bayou, on the W side of Perdido Pass 0.7 miles above the entrance, Old River enters Perdido Pass from the east between Florida Point and Ono Island. In May 1982, a depth of 5 feet could be carried through the river. The Florida-Alabama state boundary passes along the center of Old River until 2 miles before Perdido Pass, a fixed highway bridge with a clearance of 24 feet crosses Old River, about 1 mile east of Perdido Pass. Both Alabama Point and Florida Point are in the town of Orange Beach, however, Florida Point is the tip of a peninsula originating in the U. S. State of Florida, with the final 2 miles of the tip contained within Alabama. Often U. S. state lines run through the middle of a pass or river, however, the Perido Pass is entirely within the State of Alabama. The Gulf State Park is located on Florida Point, also known as the Orange Beach Islands, the Islands of Perdido Pass are considered both recreational hangouts for boaters, and vital sanctuaries to several species of plant and animal. The islands of Orange Beach, Alabama are accessible only by watercraft, two public boat accesses are offered in Orange Beach, as well as boat launches including The Wharf or Bear Point Marina. The Islands of Perdido Pass consist of Bird Island, Robinson Island, Gilchrist Island, Walker Island, and the easternmost Rabbit Island
