Weathering & Erosion

Front

What is weathering?

Back

Weathering is the process of breaking down rocks and minerals into smaller pieces due to various factors like temperature changes, water, and biological activity.

Front

What is erosion?

Back

Erosion is the process of moving sediments from one location to another, often caused by wind, water, or ice.

Front

What is deposition?

Back

Deposition is the dropping of sediments in a new location after they have been transported by erosion.

What is the main cause of weathering at the top of a mountain?

Back

The top of a mountain weathers the fastest due to exposure to wind, rain, and temperature changes.

Front

How is soil formed?

Back

Soil is formed by the weathering of rocks, which breaks down into smaller particles that mix with organic material.

Front

What role does moving water play in erosion?

Back

Moving water is a major cause of erosion, as it can carry sediments away from their original location.

Front

What are the two main types of weathering?

Back

The two main types of weathering are mechanical weathering (physical breakdown) and chemical weathering (chemical alteration of minerals).

Front

Give an example of mechanical weathering.

Back

An example of mechanical weathering is freeze-thaw action, where water seeps into cracks in rocks, freezes, expands, and eventually breaks the rock apart.

Front

What is chemical weathering?

Back

Chemical weathering involves the chemical alteration of minerals in rocks, often due to reactions with water, acids, or gases.

Front

What is the difference between weathering and erosion?

Back

Weathering is the breakdown of rocks, while erosion is the movement of those broken pieces from one place to another.
