Weathering and Erosion

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 soil and rock are removed from one location and transported to another, often by wind, water, or ice.

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 breaking down 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 the formation of new minerals.

Front

How do tree roots contribute to weathering?

Back

Tree roots can cause physical weathering by growing into cracks in rocks and breaking them apart.

Front

What is an example of physical weathering?

Back

An example of physical weathering is ice wedging, where water freezes in rock cracks and expands, causing the rock to break.

Front

What is oxidation in the context of weathering?

Back

Oxidation is a chemical weathering process where oxygen reacts with minerals, often leading to rusting in iron-rich rocks.

Front

What happens to rocks during weathering?

Back

During weathering, rocks break into smaller pieces or change chemically, but they do not move from their original location.

Front

What role does water play in erosion?

Back

Water can erode rocks and soil by carrying them away through rivers, rain, and waves.
