Florida"s land Then and Now
The land we now contact Florida began to type by a mix of volcanic task and the deposit of maritime sediments. It formed along northwest Africa around 530 million year ago. In earliest times, Florida was part of Gondwanaland, the at sight continent that later divided into Africa and also South America. Over there is evidence that Florida separated from Gondwanaland around 300 million year ago. Florida eventually discovered itself wedged between Gondwanaland and North America when they merged to kind the supervisor continent Pangea. Once Pangea began to break up, Florida remained behind v North America. Florida slipped gradually beneath the tide to become part of phibìc America�s continent shelf. The landmass the is currently Florida stayed shallowly submerged beneath the ocean. Coral, shellfish, and fish skeletons piled up. This created a great of limestone hundreds (in some locations thousands) of feet thick. together the Appalachian mountains eroded, sand and also clay were deposited over Florida�s limestone layer. Much of the quartz sand covering the state this particular day came native the rocks of that mountain chain. Throughout many of that is history, Florida has actually been under water. Parts of the Florida peninsula have actually been above or listed below sea level in ~ least four times. Together glaciers of ice cream in the north expanded and also melted, the Florida peninsula emerged and submerged. when the sea level was lowest, the land area that Florida to be much bigger than the is now. The sea level to be as much as 100 feet lower than at present. Florida�s west coast was most likely 100 miles further out. As the climate warmed, the glaciers melted. This raised the sea level and also flooded the Florida peninsula. The sea level stood at least 100 to 150 feet over the current level. Florida probably had islands. The formation of the Florida Keys arisen when tiny coral produced a 150-mile long chain that underwater coral reefs. Together the landmass of southerly Florida began its slow-moving rise, the reefs likewise began to emerge. The Florida peninsula is the emergent part of the Florida Platform. This is a wide, fairly flat land formation. The Florida platform lies between the deep waters of the Gulf of Mexico and the Atlantic Ocean. Florida"s landscape different widely. Countless of Florida�s prominent features have result from karst, a landscape v a base layer of limestone. Since limestone is porous, freshwater progressively dissolves the rock and forms cracks and also passages. The limestone class of the state is honeycombed v underground rivers. Where the rivers break through to the surface, springs and sinkholes room found. Lakes and wetlands are abundant. return Florida is reasonably flat, over there are various elevations. They selection from 0 to 320 feet over sea level. The greatest elevations in the state are in the main highlands, which operation down the facility of the state. Florida is classified together a secure geological area. This way that return some areas may experience tremors, significant weather occasions (such together hurricanes and also tornadoes) pose greatly greater dangers to Florida than perform earthquakes. overwhelming prone locations in Florida space in one of two people low-lying coastal areas or near inland rivers and also lakes. Severe flooding troubles can result from the storm surge emerged as hurricanes strategy the shoreline. Florida�s shoreline is constantly changing. Sand is being moved approximately by wind and waves. proof indicates a trend toward worldwide warming. If the world�s temperature warms, this might mean the the sea level will increase along many of the world�s coastlines. Florida has an extended coastline and many major cities are close to the coast. Any type of rise in sea level poses a threat. Florida has a wide range of soils:red clay soils in the top Florida Panhandle deep sands on the Ridge poorly drained, sandy soils in the flatwoods organic soils in the north Everglades shallow, limerock-influenced soils in extreme South Florida. Florida is not normally thought of together a mining state. However, it ranked fifth nationally in the full value of non-fuel minerals developed in 1990. Phosphate rock, crushed stone, and also cement are the significant commodities produced. Clay, heavy minerals, magnesium compounds, oil, natural gas, peat, and also sand and gravel have additionally been produced in recent years. Florida"s land is supplied as follows: 8% for crops 30% for pasture and range 35% for woodland 27% for "other" -- transportation, parks, refuges, marshes, defense, industry, city uses, golf courses, and mining areas.
