No land animals were present in Florida prior to the Miocene. The largest deposits of rock phosphate in the United States are found in Florida. [1] Most of this is in Bone Valley in central and west-central Florida. [2] Extended systems of underwater caves, sinkholes and springs are found throughout the state and supply most of the water used ...
The platform's western edge, or Florida Escarpment, is normally defined where water depths at 300 feet (91 m) drop dramatically and in a short distance to 10,000 feet (3,000 m). The Florida peninsula is located on the eastern side of the platform, where in places it lies only 3 to 4 miles (4.8 to 6.4 km) from the platform's edge.
A shell midden at Enterprise, Florida in 1875.. The foundation of Florida was located in the continent of Gondwana at the South Pole 650 million years ago (Mya). When Gondwana collided with the continent of Laurentia 300 Mya, it had moved further north. 200 Mya, the merged continents containing what would be Florida, had moved north of the equator.
At 345 feet (105 m) above mean sea level, Britton Hill in northern Walton County is the highest point in Florida and the lowest known highpoint of any U.S. state. [3] Much of the state south of Orlando is low-lying and fairly level; however, some places, such as Clearwater, feature vistas that rise 50 to 100 feet (15 to 30 m) above the water.
At the time, Earth's continents were in a very different arrangement and were generally smaller than they are today. The southeastern part of the US was connected to South America and Africa and located in the polar latitudes of the southern hemisphere. The western states were located near the equator. [7]
The Florida Current results from the movement of water pushed from the Atlantic into the Caribbean Sea by the rotation of the Earth (which exerts a greater force at the equator). The water piles up along Central America and flows northward through the Yucatán Channel into the Gulf of Mexico .
The images, captured one day after the storm struck the region, show beaches in Siesta Key and Anna Maria Island, another barrier island just north of Milton's landfall site, darkened and damaged ...
In order to understand the origins of this concentrated band of Earth hazards, we have to slice deep into the Earth. [4] The Cascade Range is formed by an active continental margin. A slice of the Earth from the Pacific Ocean through the Pacific Northwest might look something like the adjacent image.
