Front

What is weathering?

Back

The process of breaking down rocks into smaller pieces through physical or chemical means.

Front

What is erosion?

Back

The movement of sediments from one location to another, often caused by wind, water, or ice.

Front

What is deposition?

Back

The dropping off of sediments in a new place after being transported by erosion.

Front

What is physical weathering?

Back

The process of breaking rocks into smaller pieces without changing their chemical composition.

Front

What is chemical weathering?

Back

The process that alters the chemical structure of rocks, often resulting in new materials.

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 type of rock is most commonly associated with cave formation?

Back

Limestone, due to its susceptibility to chemical weathering.

Front

What is the difference between physical and chemical weathering?

Back

Physical weathering breaks rocks into smaller pieces without changing their composition, while chemical weathering changes the chemical structure of the rocks.

Front

What is an example of erosion?

Back

The wearing away of soil and rock by wind or water, such as a river carrying sediment downstream.

Front

What is a delta?

Back

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