Constructive and Destructive Forces Flashcard Review

Front

What is a constructive force?

Back

A constructive force is a natural process that builds up landforms, such as the formation of mountains, valleys, and islands.

Front

What is a destructive force?

Back

A destructive force is a natural process that breaks down landforms, such as erosion, weathering, and volcanic eruptions.

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from the Earth's surface by wind, water, or ice.

Front

What is deposition?

Back

Deposition is the process by which sediments, soil, and rocks are added to a landform or land mass.

Front

How does wind contribute to constructive processes?

Back

Wind can transport sand and other materials, depositing them in new locations, which can create dunes and other landforms.

Front

What is weathering?

Back

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

Front

Give an example of a constructive process.

Back

An example of a constructive process is the formation of a delta at the mouth of a river where sediment is deposited.

Front

Give an example of a destructive process.

Back

An example of a destructive process is a landslide, where soil and rock are rapidly moved down a slope.

Front

Where are smooth and rounded rocks typically found?

Back

Smooth and rounded rocks are typically found in fast-moving rivers where they are worn down by the water.

Front

What role does gravity play in constructive processes?

Back

Gravity helps in the deposition of materials, such as sand and soil, as it pulls them down to lower areas.
