Landforms Lessons 5 - 8

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from the Earth's surface by natural processes such as wind or water flow.

Front

What is weathering?

Back

Weathering is the breaking down of rocks and minerals into smaller pieces by natural processes, including physical and chemical changes.

Front

What causes a valley to form?

Back

A valley can form through the process of erosion, where rivers or glaciers carve out the land over time.

Front

What is deposition?

Back

Deposition is the process where materials are added to a landform, such as when sediment settles out of water.

Front

How does acid rain affect rocks?

Back

Acid rain can dissolve certain types of rocks through a process called weathering, leading to changes in the landscape.

Front

What are the Appalachian Mountains?

Back

The Appalachian Mountains are a mountain range in eastern North America, known for their age and the processes of weathering and erosion that have shaped them.

Front

What is the difference between physical and chemical weathering?

Back

Physical weathering breaks rocks into smaller pieces without changing their chemical composition, while chemical weathering alters the minerals within the rocks.

Front

What is sedimentation?

Back

Sedimentation is the process of settling or being deposited as sediment, often in bodies of water.

Front

What role does water play in erosion?

Back

Water can carry away soil and rock particles, leading to erosion, especially during heavy rainfall or flooding.

Front

What is a landform?

Back

A landform is a natural feature of the Earth's surface, such as mountains, valleys, plateaus, and hills.
