Weathering and Erosion

Front

What is weathering?

Back

Weathering is the process of breaking down rocks and minerals into smaller pieces due to natural forces such as wind, water, and temperature changes.

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 forming new features like deltas and sand dunes.

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

How do sand dunes form?

Back

Sand dunes form through the deposition of sand by wind, creating mounds or hills of sand.

Front

What role does wind play in weathering?

Back

Wind can cause weathering by blasting sand and other particles against rocks, breaking them down over time.

Front

What is the difference between weathering and erosion?

Back

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

Front

Can you give an example of erosion?

Back

An example of erosion is a river cutting through rock and soil, gradually changing the landscape.

Front

What is an example of deposition?

Back

An example of deposition is the accumulation of sand at the beach, forming new land features.

Front

What is mechanical weathering?

Back

Mechanical weathering is the physical breakdown of rocks into smaller pieces without changing their chemical composition.
