Weathering, Erosion & Deposition

Front

What is weathering?

Back

Weathering is the process of breaking down rocks and minerals 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 in which sediments, soil, and rocks are added to a landform or land mass, often occurring after erosion.

Front

What is abrasion in the context of weathering?

Back

Abrasion is a type of mechanical weathering where rocks and sediments are worn down by friction and impact during transport.

Front

What role do animals play in erosion?

Back

Animals can contribute to erosion through their burrowing and digging activities, which disturb the soil and rock.

Front

What is oxidation in geological terms?

Back

Oxidation is a chemical weathering process where minerals react with oxygen, often leading to the formation of rust in iron-rich rocks.

Front

How does water contribute to weathering?

Back

Water contributes to weathering through processes like freeze-thaw cycles, chemical reactions, and abrasion.

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 within the rocks.

Front

What are the main agents of erosion?

Back

The main agents of erosion include water, wind, ice, and gravity.

Front

How does vegetation affect erosion?

Back

Vegetation helps to reduce erosion by stabilizing soil with roots and absorbing water, which decreases runoff.
