History Of Florida
The history of Florida can be traced to when the first Paleo-Indians began to inhabit the peninsula as early as 14,000 years ago. They left behind artifacts and archeological remains. Florida's Recorded history, written history begins with the arrival of Europeans; the Spanish explorer Juan Ponce de León in 1513 made the first textual records. The state received its name from that ''conquistador'', who called the peninsula ''La Pascua Florida'' in recognition of the verdant landscape and because it was the Easter season, which the Spaniards called ''Pascua Florida'' (Festival of Flowers). This area was the first mainland realm of the United States to be settled by Europeans, starting in 1513. Since then Florida has had many waves of colonization and immigration, including French and Spanish settlement during the 16th century, as well as entry of new Native American groups migrating from elsewhere in the South, and free black people and fugitive slaves, who in the 19th century bec ...

Paleo-Indians
Paleo-Indians were the first peoples who entered and subsequently inhabited the Americas towards the end of the Late Pleistocene period. The prefix ''paleo-'' comes from . The term ''Paleo-Indians'' applies specifically to the lithic period in the Western Hemisphere and is distinct from the term ''Paleolithic''.''Paleolithic'' specifically refers to the period between million years ago and the end of the Pleistocene in the Eastern Hemisphere. It is not used in New World archaeology. Traditional theories suggest that big-animal hunters crossed the Bering Strait from North Asia into the Americas over a land bridge ( Beringia). This bridge existed from 45,000 to 12,000 BCE (47,000–14,000 BP). Small isolated groups of hunter-gatherers migrated alongside herds of large herbivores far into Alaska. From BCE ( BP), ice-free corridors developed along the Pacific coast and valleys of North America. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gondwana
Gondwana ( ; ) was a large landmass, sometimes referred to as a supercontinent. The remnants of Gondwana make up around two-thirds of today's continental area, including South America, Africa, Antarctica, Australia (continent), Australia, Zealandia, Arabian Peninsula, Arabia, and the Indian subcontinent. Gondwana was formed by the Accretion (geology), accretion of several cratons (large stable blocks of the Earth's crust), beginning with the East African Orogeny, the collision of India and Geography of Madagascar, Madagascar with East Africa, and culminating in with the overlapping Brasiliano orogeny, Brasiliano and Kuunga orogeny, Kuunga orogenies, the collision of South America with Africa, and the addition of Australia and Antarctica, respectively. Eventually, Gondwana became the largest piece of continental crust of the Paleozoic Era, covering an area of some , about one-fifth of the Earth's surface. It fused with Laurasia during the Carboniferous to form Pan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Artifact (archaeology)
An artifact or artefact (British English) is a general term for an item made or given shape by humans, such as a tool or a work of art, especially an object of archaeological interest. In archaeology, the word has become a term of particular nuance; it is defined as an object recovered by archaeological endeavor, including cultural artifacts (of archaeological culture, cultural interest). "Artifact" is the general term used in archaeology, while in museums the equivalent general term is normally "object", and in art history perhaps artwork or a more specific term such as "carving". The same item may be called all or any of these in different contexts, and more specific terms will be used when talking about individual objects, or groups of similar ones. Artifacts exist in many different forms and can sometimes be confused with Biofact (archaeology), ecofacts and Feature (archaeology), features; all three of these can sometimes be found together at archaeological sites. They can a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aucilla River
The Aucilla River rises in Brooks County, Georgia, Brooks County, Georgia (U.S. state), Georgia, USA, close to Thomasville, Georgia, Thomasville, and passes through the Big Bend (Florida), Big Bend region of Florida, emptying into the Gulf of Mexico at Apalachee Bay. Some early maps called it the Ocilla River. It is long and has a drainage basin of . Tributaries include the Little Aucilla and Wacissa Rivers. In Florida, the Aucilla River forms the eastern border of Jefferson County, Florida, Jefferson County, separating it from Madison County, Florida, Madison County on the northern part, and from Taylor County, Florida, Taylor County to the south. During the Spanish Florida, first Spanish period in Florida the Aucilla River was the boundary between the Apalachee people and the Timucua language, Timucua-speaking Yustaga (or Uzachile) people. The name "Aucilla" refers to an old Timucua village. Course and features The Aucilla River flows across a karst landscape, Subterranean ...

Limestone
Limestone is a type of carbonate rock, carbonate sedimentary rock which is the main source of the material Lime (material), lime. It is composed mostly of the minerals calcite and aragonite, which are different Polymorphism (materials science), crystal forms of calcium carbonate . Limestone forms when these minerals Precipitation (chemistry), precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly Dolomite (rock), dolomite, a closely related rock, which contains a high percentage of the mineral Dolomite (mine ...

Sinkhole
A sinkhole is a depression or hole in the ground caused by some form of collapse of the surface layer. The term is sometimes used to refer to doline, enclosed depressions that are also known as shakeholes, and to openings where surface water enters into underground passages known as ''ponor'', swallow hole or swallet. A ''cenote'' is a type of sinkhole that exposes groundwater underneath. ''Sink'', and ''stream sink'' are more general terms for sites that drain surface water, possibly by infiltration into sediment or crumbled rock. Most sinkholes are caused by Karst topography, karst processes – the chemical dissolution of carbonate rocks, collapse or suffosion processes. Sinkholes are usually circular and vary in size from tens to hundreds of Metre, meters both in diameter and depth, and vary in form from soil-lined bowls to bedrock-edged chasms. Sinkholes may form gradually or suddenly, and are found worldwide. Formation Natural processes Sinkholes may capture surf ...

Wetland
A wetland is a distinct semi-aquatic ecosystem whose groundcovers are flooded or saturated in water, either permanently, for years or decades, or only seasonally. Flooding results in oxygen-poor ( anoxic) processes taking place, especially in the soils. Wetlands form a transitional zone between waterbodies and dry lands, and are different from other terrestrial or aquatic ecosystems due to their vegetation's roots having adapted to oxygen-poor waterlogged soils. They are considered among the most biologically diverse of all ecosystems, serving as habitats to a wide range of aquatic and semi-aquatic plants and animals, with often improved water quality due to plant removal of excess nutrients such as nitrates and phosphorus. Wetlands exist on every continent, except Antarctica. The water in wetlands is either freshwater, brackish or saltwater. The main types of wetland are defined based on the dominant plants and the source of the water. For example, ''marshes'' ar ...

Quaternary Glaciation
The Quaternary glaciation, also known as the Pleistocene glaciation, is an alternating series of glacial period, glacial and interglacial, interglacial periods during the Quaternary period that began 2.58 Year#SI prefix multipliers, Ma (million years ago) and is ongoing. Although geologists describe this entire period up to the present as an "ice age", in popular culture this term usually refers to the Last Glacial Period, most recent glacial period, or to the Pleistocene epoch in general. Since Earth still has polar Ice sheet, ice sheets, geologists consider the Quaternary glaciation to be ongoing, though currently in an interglacial period. During the Quaternary glaciation, ice sheets appeared, expanding during glacial periods and contracting during interglacial periods. Since the end of the last glacial period, only the Antarctic ice sheet, Antarctic and Greenland ice sheets have survived, while other sheets formed during glacial periods, such as the Laurentide Ice Sheet, hav ...

Florida Platform
The Florida Platform is a flat geological feature with the emergent portion forming the Florida peninsula. Structure The platform forms an escarpment between the Gulf of Mexico and the Atlantic Ocean. The platform's western edge, or Florida Escarpment, is normally defined where water depths at drop dramatically and in a short distance to . The Florida peninsula is located on the eastern side of the platform, where in places it lies only from the platform's edge. On the gulf side the platform ends over to the west of the modern shoreline, where a massive cliff rises over from the depth of the gulf floor. The western reaches of the platform just off Tampa were explored by the submersible DSV ''Alvin''. Examination has placed the depth of carbonate rocks at greater than . Geology The platform's basement rocks include Precambrian–Cambrian igneous rocks, Ordovician–Devonian sedimentary rocks, and Triassic–Jurassic volcanic rock. Florida's igneous and sedimentary foundati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orange Island (Florida)
Orange Island is the earliest emergent landmass of Florida dating from the middle Rupelian ~33.9—28.4 Ma. geologic stage of the Early Oligocene epoch and named for Orange County, Florida, United States of America. Location Orange Island's general location is east of or on the eastern part of the Ocala Platform running north to south. Edward J. Petuch states that Orange Island was a dominant geomorphological feature of the Bainbridge Subsea on the Florida Platform According to J. R. Bryan and the United States Geological Survey, a lack of deposition with reference to the eastern side of the Ocala Platform indicates this area as Orange Island. The island also bounded the Okeechobean Sea to its south. Origins During the warm Eocene ~55.8—33.9 Ma., what was to become Florida (Florida Platform) was a carbonate bank with shallow sea covering it. During the Eocene, biological carbonates were deposited on this bank forming various layers. The Avon Park Formation and Ocala Lim ...
