Erosion, weathering and deposition

Front

What is erosion?

Back

Erosion is the process by which soil, rock, or other surface material is worn away and removed from one location to another, often by wind, water, or ice.

Front

What is weathering?

Back

Weathering is the breaking down of rocks and minerals into smaller pieces by natural processes such as wind, water, and temperature changes.

Front

What is deposition?

Back

Deposition is the process by which sediments, soil, and rocks are added to a landform or land mass, often occurring at the end of rivers or in bodies of water.

Front

How does erosion differ from weathering?

Back

Erosion involves the movement of materials from one place to another, while weathering is the process of breaking down materials without movement.

Front

What natural forces can cause erosion?

Back

Natural forces that can cause erosion include water (rivers, rain), wind, ice (glaciers), and gravity.

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.

Front

Can weathering occur without erosion?

Back

Yes, weathering can occur without erosion; it involves breaking down materials without moving them.

Front

What role does water play in weathering?

Back

Water can cause weathering through processes like freeze-thaw cycles, where water seeps into cracks, freezes, expands, and breaks the rock apart.

Front

What is the rock cycle?

Back

The rock cycle is the continuous process of rock formation, breakdown, and reformation, involving igneous, sedimentary, and metamorphic rocks.

Front

What is mechanical weathering?

Back

Mechanical weathering is the physical breakdown of rocks into smaller pieces without changing their chemical composition.
