Back

Sand dunes form when wind blows sand from one location to another, causing it to accumulate in a new area.

What is the role of limestone in sinkhole formation?

Back

Limestone is a soluble rock that can dissolve in water, leading to the formation of caverns. When these caverns collapse, they create sinkholes.

What is physical weathering?

Back

Physical weathering is the process of breaking down rocks through physical forces, such as freeze-thaw cycles, without changing their chemical composition.

Front

What is chemical weathering?

Back

Chemical weathering involves the chemical alteration of minerals in rocks, often through reactions with water, acids, or other chemicals.
