Weathering, Erosion, and Deposition Review

Front

What is weathering?

Back

The process of breaking down rocks and minerals into smaller pieces through physical, chemical, or biological means.

Front

What is erosion?

Back

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

The process in which sediments, soil, and rocks are added to a landform or land mass, often occurring after erosion.

Front

What role does wind play in erosion?

Back

Wind can erode land by carrying away loose particles and sediments, especially in dry areas.

Front

What is chemical weathering?

Back

The process that breaks down rocks through chemical reactions, often involving water and substances like acids.

Front

What is abrasion in the context of weathering?

Back

The process of wearing down rocks through friction and impact, often caused by wind or water carrying particles.

Front

How do sand dunes form?

Back

Sand dunes are formed by wind depositing sand particles in a specific area, creating mounds.

Front

What is the main force responsible for landslides?

Back

Gravity is the primary force that causes landslides, rockfalls, and mudslides.

Front

What is hydrolysis in chemical weathering?

Back

A chemical weathering process where water reacts with minerals to form new minerals and soluble salts.

Front

What is oxidation in chemical weathering?

Back

A process where oxygen reacts with minerals, often leading to the rusting of iron-rich rocks.
