Weathering and Erosion

Front

What is weathering?

Back

Weathering is the process of breaking down rocks into smaller pieces through natural forces like wind, water, and temperature changes.

Front

What is erosion?

Back

Erosion is the process of moving weathered rock and soil from one place to another, often by water, wind, or ice.

Front

What is deposition?

Back

Deposition is the process where sediments, soil, and rocks are added to a landform or land mass, often occurring in areas like river deltas and beaches.

Front

How does freezing water cause weathering of rocks?

Back

Freezing water expands in cracks of rocks, causing them to break apart.

Front

Are weathering and erosion the same thing?

Back

No, weathering is the breaking down of rocks, while erosion is the movement of those broken pieces.

Front

What is an example of deposition?

Back

An example of deposition is the formation of a delta at the mouth of a river.

Front

What role do waves play in deposition?

Back

Waves can drop sand and other materials on the beach, contributing to deposition.

Front

What is the difference between mechanical and chemical weathering?

Back

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

Front

What is an example of mechanical weathering?

Back

An example of mechanical weathering is when water seeps into cracks in rocks, freezes, and expands, causing the rocks to break.

Front

What is an example of chemical weathering?

Back

An example of chemical weathering is when acid rain reacts with limestone, causing it to dissolve.
