Weathering and Erosion Review

Front

What is weathering?

Back

Weathering is the process that breaks down rocks and minerals into smaller pieces through mechanical or chemical 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.

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, leading to their breakdown.

Front

What is a delta?

Back

A delta is a landform that forms at the mouth of a river where it meets a body of water, created by the deposition of sediment.

Front

What is mass wasting?

Back

Mass wasting is the movement of rock and soil down a slope due to gravity.

Front

What role do waves play in erosion?

Back

Waves can erode coastlines by wearing away rocks and sediments, shaping landforms like sea arches.

Front

What happens to a hole in a landform due to erosion?

Back

As erosion continues, the hole in a landform will likely get bigger.

Front

How does weathering differ from erosion?

Back

Weathering breaks down rocks in place, while erosion involves the movement of those broken materials.
