Beneath Florida are
structures made up mostly with carbonaceous rock such as limestone and
dolostone overlaid with mixtures of sand and clay. When groundwater passes
through this structure, the carbonates are slowly dissolved and thus creating sinkholes.
<span>For centuries, sinkholes have
found popular use as disposal sites for various forms of waste.</span>
The Earth's rocky outer crust solidified billions of
years ago, soon after the Earth formed. This crust is not a solid
shell; it is broken up into huge, thick plates that drift atop the soft,
underlying mantle.
The plates are made of rock and drift all over the globe; they move both
horizontally (sideways) and vertically (up and down). Over long
periods of time, the plates also change in size as their margins are
added to, crushed together, or pushed back into the Earth's mantle. These plates are from 50 to 250 miles (80 to 400 km) thick.
Explanation:
Urban Population Density, Climate Change, and Disasters The dense concentration of urban populations can increase susceptibility to the disasters that are likely to become more frequent and more intense as a result of climate change. Many aspects of urban areas are vulnerable to disasters and climate change.
<span>Guyots are seamounts that have built above sea level. Erosion by waves destroyed the top of the seamount resulting in a flattened shape. Due to the movement of the ocean floor away from oceanic ridges, the sea floor gradually sinks and the flattened guyots are submerged to become undersea flat-topped peaks.</span>
