Weathering, Erosion, and Deposition

Front

What is weathering?

Back

Weathering is the process that breaks down rocks into smaller pieces through physical or chemical means.

Front

What is erosion?

Back

Erosion is the process by which weathered rock and soil are moved from one place to another by water, wind, ice, or gravity.

Front

What is deposition?

Back

Deposition is the process where sediments are dropped off and settle at the bottom of a body of water or on land.

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 chemical weathering?

Back

Chemical weathering involves the chemical alteration of minerals in rocks, often leading to their breakdown.

Front

How does water contribute to weathering?

Back

Water can cause both mechanical and chemical weathering; it can freeze and expand in cracks (mechanical) or react with minerals (chemical).

Front

What role does temperature play in weathering?

Back

Temperature changes can cause rocks to expand and contract, leading to mechanical weathering.

Front

What is an example of erosion?

Back

An example of erosion is a river carrying away soil and rocks as it flows.

Front

What is an example of deposition?

Back

An example of deposition is sand being deposited on a beach by ocean waves.

Front

What is the difference between weathering and erosion?

Back

Weathering breaks down rocks, while erosion moves the broken pieces away.
