What is chemical weathering?

Back

Chemical weathering is the process that breaks down rocks through chemical reactions, altering their composition.

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 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 sediments, soil, and rocks are added to a landform or land mass.

Front

What factors affect the rate of weathering?

Back

Factors include the type of rock, climate, presence of water, and biological activity.

Front

What is exfoliation in mechanical weathering?

Back

Exfoliation is the process where outer layers of rock peel away due to temperature changes.

Front

What is ice wedging?

Back

Ice wedging is a type of mechanical weathering where water seeps into cracks, freezes, and expands, causing the rock to break apart.

Front

What role does acid rain play in weathering?

Back

Acid rain contributes to chemical weathering by reacting with minerals in rocks, leading to their breakdown.

Front

What is oxidation in the context of weathering?

Back

Oxidation is a chemical weathering process where oxygen reacts with minerals, often leading to rusting in iron-rich rocks.

Front

How does the composition of a rock affect its weathering rate?

Back

Different minerals weather at different rates; softer minerals weather faster than harder ones.
