What is weathering?

Back

Weathering is the process that breaks down rocks into smaller pieces through physical, chemical, or biological means.

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from one location and transported to another, often by wind, water, or ice.

Front

What is deposition?

Back

Deposition is the process where materials are laid down or settled after being transported by erosion.

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, leading to their breakdown.

Front

How does freezing water cause weathering?

Back

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

Front

What role do plants play in weathering?

Back

Plants can cause weathering through root growth, which can break apart rocks.

Front

What is the difference between weathering and erosion?

Back

Weathering breaks down rocks in place, while erosion involves the movement of those broken materials.

Front

What is an example of erosion caused by wind?

Back

Wind can blow sand from one location to another, shaping landscapes.

Front

What is an example of chemical weathering?

Back

An example of chemical weathering is the reaction of acid rain with limestone, which dissolves the rock.
