What is abrasion in the context of weathering?

Back

Abrasion is the process of wearing down surfaces by friction, often caused by wind or water carrying particles.

Front

How does water contribute to weathering?

Back

Water can cause weathering through processes like freeze-thaw cycles, where water seeps into cracks, freezes, and expands, breaking the rock apart.

Front

What is chemical weathering?

Back

Chemical weathering involves the chemical alteration of minerals in rocks, often due to reactions with water or acids.
