Back

Weathering is the breakdown of rocks, while erosion is the movement of those broken pieces.

Front

What role does water play in weathering?

Back

Water can cause both physical weathering (through freeze-thaw cycles) and chemical weathering (by dissolving minerals).

Front

What is mechanical weathering?

Back

The physical breakdown of rocks into smaller pieces without changing their chemical composition.

Front

What is chemical weathering?

Back

The process that breaks down rocks through chemical reactions, often involving water and acids.

Front

What is biological weathering?

Back

Weathering caused by living organisms, such as plant roots growing into cracks in rocks.
