Weathering is the breaking down of rocks, soils, and minerals as well as wood and artificial materials through contact with the Earth's atmosphere, water, and biological organisms.Weathering occurs in situ (i.e., on site, without displacement), that is, in the same place, with little or no movement, and thus should not be confused with erosion, which involves the transport of rocks and ...

How sinkholes form – SJRWMD

Sinkholes are part of the slow, natural process of erosion in Florida's limestone terrain that occur over thousands of years. These common geologic phenomena generally occur where the limestone is within a few hundred feet of the land's surface.

How Sinkholes Work | HowStuffWorks

As limestone dissolves and leaves a void, sediment from the overburden seeps in, creating a bowl-like impression in the Earth. These sinkholes, often only a few feet across and deep, are smaller than many others because after reaching a certain size, sand and sediment pour into the hole [source: Southwest Florida Water Management District ].
