What is physical weathering?

Back

The mechanical breakdown of rocks without changing their chemical composition.

Front

Give an example of a process that causes physical weathering.

Back

Frost wedging, where water freezes in cracks of rocks and expands.

Front

What role does temperature play in physical weathering?

Back

Temperature changes can cause rocks to expand and contract, leading to fractures.

Front

What is the main difference between physical and chemical weathering?

Back

Physical weathering involves mechanical processes, while chemical weathering involves chemical reactions.

Front

How does water contribute to chemical weathering?

Back

Water can dissolve minerals and facilitate chemical reactions that break down rocks.
