Weathering, Erosion and Deposition

Front

What is weathering?

Back

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

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 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 after erosion.

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 causes landslides?

Back

Landslides are caused by the movement of rock and soil down a slope, often triggered by heavy rain, earthquakes, or human activity.

Front

How do rivers contribute to erosion?

Back

Rivers contribute to erosion by carrying away soil and rock as they flow, especially during heavy rains or floods.

Front

What role does wind play in shaping the landscape?

Back

Wind can cause erosion by carrying away loose particles and can also lead to deposition by dropping sand and dust in new locations.

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 is the difference between weathering and erosion?

Back

Weathering breaks down rocks in place, while erosion involves the movement of those broken materials to a new location.

Front

What is an example of mechanical weathering?

Back

An example of mechanical weathering is when water seeps into cracks in rocks, freezes, and expands, causing the rock to break apart.
