Document Summary
Why: kentucky and florida and pennsylvania because where surface water tends to percolate into the ground, recharging aquifers below, what is karst and how does it form, karst is limestone bedrock that is uneven and potholed upper surface. It is form by rainwater + carbon dioxide = carbonic acid in water. Why: periods of heavy rainfall tend to loosen soil, enlarge cavities, and promote sinkholes. Damage also occur when adjacent areas swell at different rates. Climate change: explain the orographic effect on weather, most air reaches land and is forced to rise over a mountain range, it expands adiabatically and cools. Large currents of air and surface water tend to curve to the right in the north and curve to the left in the sout. Ocean currents move westward as they flow toward the equator and eastward as they head toward the poles.
