Weathering, Erosion and Deposition

Front

What is weathering?

Back

Weathering is the process of wearing away or breaking down rocks into smaller pieces due to natural forces like wind, water, and temperature changes.

What is erosion?

Back

Erosion is the movement of weathered rock and soil from one location to another, often caused by water, wind, 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 when the transporting medium loses energy.

Front

What is a glacier?

Back

A glacier is an enormous mass of ice that moves slowly over land, causing weathering and erosion of rocks and soil.

Front

What is a U-shaped valley?

Back

A U-shaped valley is a valley formed by the erosion of a glacier, characterized by its steep sides and flat bottom.

Front

What is a canyon?

Back

A canyon is a deep valley with steep sides, often formed by the erosion of a river over a long period.

Front

What is a delta?

Back

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

Front

What is a landslide?

Back

A landslide is the sudden and fast movement of rock and soil down a slope, often triggered by heavy rain or earthquakes.

Front

What role does water play in weathering?

Back

Water contributes to weathering by dissolving minerals, freezing and thawing, and transporting sediments.

Front

How do plants contribute to weathering?

Back

Plants contribute to weathering through their roots, which can break apart rocks as they grow and by producing acids that help dissolve minerals.
