What is weathering?

Back

Weathering is the process of breaking down rocks into sediment.

Front

What is mechanical weathering?

Back

Mechanical weathering is the process of breaking rocks into smaller pieces without changing their chemical composition.

Front

What is chemical weathering?

Back

Chemical weathering is the process that alters the chemical composition of rocks, often leading to their breakdown.

What role do plant roots play in weathering?

Back

Plant roots can cause both physical and chemical weathering by breaking rocks apart and altering their composition.

Front

What is abrasion in the context of weathering?

Back

Abrasion is the process of rocks being worn smooth by the friction of wind or water carrying smaller particles.

Front

What is the difference between physical and chemical weathering?

Back

Physical weathering breaks rocks into smaller pieces without changing their composition, while chemical weathering changes the minerals within the rocks.

What is an example of physical weathering?

Back

An example of physical weathering is ice wedging, where water freezes in rock cracks and expands.

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.
