Weathering, Erosion and Deposition

Front

What is weathering?

Back

Weathering is the process of breaking down rocks and minerals into smaller pieces through physical, chemical, or biological 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 is deposition?

Back

Deposition is the process where sediments, soil, and rocks are added to a landform or land mass, often occurring at the mouth of rivers or in lakes.

Front

What causes chemical weathering?

Back

Chemical weathering is caused by chemical reactions, such as acidity and oxidation, that alter the minerals in rocks.

Front

What is physical weathering?

Back

Physical weathering is the process of breaking rocks into smaller pieces without changing their chemical composition, often through temperature changes or freeze-thaw cycles.

Front

How do glaciers contribute to weathering?

Back

Glaciers contribute to weathering by scraping and grinding rocks as they move, which breaks down the rocks into smaller particles.

Front

What is an example of erosion?

Back

An example of erosion is the wearing away of riverbanks by flowing water, which transports soil and sediment downstream.

Front

What is a delta?

Back

A delta is a landform that forms at the mouth of a river where it meets a body of water, created by the deposition of sediment carried by the river.

Front

What role does wind play in erosion?

Back

Wind can erode surfaces by carrying away loose particles, especially in dry and sandy environments.

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.
