What is weathering?

Back

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

Front

What is erosion?

Back

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

The geological process where sediments, soil, and rocks are added to a landform or land mass.

Front

What causes physical weathering?

Back

Physical weathering is caused by mechanical processes such as freeze-thaw cycles, abrasion, and temperature changes.

Front

What is chemical weathering?

Back

Chemical weathering involves the alteration of the chemical composition of rocks, often due to reactions with water, acids, or oxygen.

Front

How do rivers contribute to erosion?

Back

Rivers erode the land by carrying away soil and rock as they flow, shaping the landscape over time.

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.

Front

What role does acid rain play in weathering?

Back

Acid rain can chemically weather rocks, especially limestone, leading to the formation of caves.

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 new locations.

Front

What is an example of physical weathering?

Back

An example of physical weathering is the cracking of rocks due to freeze-thaw cycles.
