How do plants contribute to weathering?

Back

Plants contribute to weathering by growing roots into cracks in rocks, which can expand and break the rocks apart.

Front

What role does water play in erosion?

Back

Front

What is the difference between weathering and erosion?

Back

Weathering breaks down rocks, while erosion moves the broken pieces away from their original location.

Front

Can weathering occur without erosion?

Back

Yes, weathering can occur without erosion; rocks can break down in place without being moved.

Front

What is mechanical weathering?

Back

Mechanical weathering is the physical breakdown of rocks into smaller pieces without changing their chemical composition.

Front

What is chemical weathering?

Back

Chemical weathering involves the chemical alteration of minerals in rocks, often leading to their breakdown.
