Weathering, Erosion and Deposition

Front

What is weathering?

Back

Weathering is the process of breaking down rocks 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 end of rivers or in lakes.

Front

How do plants contribute to weathering?

Back

Plants weather rocks by growing roots into cracks, which can expand and break the rock apart.

Front

What is a delta?

Back

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

Front

What are the main agents of erosion?

Back

The main agents of erosion are water, wind, ice, and gravity.

Front

What is mechanical weathering?

Back

Mechanical weathering is the physical breakdown 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, often leading to their breakdown.

Front

What role does carbonic acid play in weathering?

Back

Carbonic acid, formed when carbon dioxide dissolves in water, helps dissolve limestone and contributes to the formation of caves.

Front

What is the difference between erosion and weathering?

Back

Weathering is the breakdown of rocks, while erosion is the movement of those broken materials from one place to another.
