Erosion and Weathering: Science 5.1

Front

What is erosion?

Back

Erosion is the process of moving rock and soil from one place to another, often caused by water, wind, or ice.

Front

What is weathering?

Back

Weathering is the breaking down of rocks and minerals into smaller pieces without moving them.

Front

Which natural force is the main cause of erosion?

Back

Water is the main cause of erosion.

Front

What are the two main types of weathering?

Back

The two main types of weathering are physical weathering and chemical weathering.

Front

What is physical weathering?

Back

Physical weathering is the process of breaking down 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 new minerals.

Front

What is an example of erosion caused by wind?

Back

An example of erosion caused by wind is the formation of sand dunes.

Front

What is gravity's role in erosion?

Back

Gravity causes mass movements like landslides and mudslides, which are forms of erosion.

Front

What is frost wedging?

Back

Frost wedging is a type of physical weathering where water seeps into cracks in rocks, freezes, and expands, causing the rock to break apart.

Front

Can weathering produce new soil?

Back

Yes, weathering can produce new soil by breaking down rocks into smaller particles that mix with organic material.
