Weathering, Erosion & Deposition

Front

What is weathering?

Back

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

Front

What role do plants play in weathering?

Back

Plants contribute to weathering by breaking down rocks through physical means (roots growing in cracks) and chemical means (producing acids that dissolve minerals).

Front

What is the main cause of erosion in rivers?

Back

The main cause of erosion in rivers is the flowing water, which can carry away soil and rock particles.

Front

How does wind contribute to erosion?

Back

Wind can erode surfaces by lifting and carrying away loose particles, especially in dry and sandy areas.

Front

What is the difference between physical and chemical weathering?

Back

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

Front

What is a silt fence used for?

Back

A silt fence is used to intercept and filter sediment-laden runoff, helping to prevent erosion.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases), where warmer areas rise and cooler areas sink.

Front

What is the impact of acid rain on rocks?

Back

Acid rain can chemically weather rocks by dissolving minerals and altering their structure.
