Front

What is mechanical weathering?

Back

The process of breaking a large rock into smaller pieces without changing the minerals.

Front

What is an example of mechanical weathering?

Back

Freezing water breaking rocks apart.

Front

What are the pieces of rock formed by weathering called?

Back

Sediments.

Front

What is chemical weathering?

Back

The process of changing the minerals in rocks through chemical reactions.

Front

What is the effect of acid rain on rocks?

Back

Acid rain causes chemical weathering of rocks.

Front

What is deposition?

Back

The dropping of sediment.

Front

What is erosion?

Back

The process of moving sediments from one location to another.

Front

What is the difference between mechanical and chemical weathering?

Back

Mechanical weathering breaks rocks into smaller pieces without changing their composition, while chemical weathering alters the minerals in the rocks.

Front

What role does water play in weathering?

Back

Water can cause both mechanical weathering (freezing and thawing) and chemical weathering (dissolving minerals).

Front

What is frost wedging?

Back

A type of mechanical weathering where water freezes in cracks of rocks, expanding and breaking the rock apart.
