Constructive and Destructive Forces

Front

What are constructive forces?

Back

Constructive forces are natural processes that build up the Earth's surface, creating new landforms such as mountains, valleys, and islands.

Front

What are destructive forces?

Back

Destructive forces are natural processes that break down and wear away the Earth's surface, such as erosion, weathering, and volcanic eruptions.

Front

What is deposition?

Back

Deposition is the process by which sediments, soil, and rocks are added to a landform or land mass, often forming new features over time.

Front

How do volcanoes change the Earth's surface?

Back

Volcanoes change the Earth's surface quickly by erupting lava, ash, and gases, which can create new landforms like islands and mountains.

Front

What role do plants play in weathering rocks?

Back

Plants weather rocks by having their roots grow into cracks, which can expand and break the rocks over time.

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 and transported to another location.

Front

How do waves act as destructive forces?

Back

Waves can wear away at the Earth's coast over time, changing its shape by eroding rocks and transporting sediments.

Front

What is the difference between weathering and erosion?

Back

Weathering is the breaking down of rocks and minerals at the Earth's surface, while erosion is the movement of those materials from one place to another.

Front

What is an example of a constructive force?

Back

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

Front

What is an example of a destructive force?

Back

An example of a destructive force is a landslide, which can rapidly remove soil and rock from a hillside.
