WED lesson 8

Front

What is mechanical weathering?

Back

Mechanical weathering is the process of breaking down rocks into smaller pieces without changing their chemical composition.

Front

What are dunes?

Back

Dunes are mounds of wind-deposited sand found in deserts and on shorelines.

Front

How does the speed of a stream affect its ability to carry loads?

Back

Faster moving streams can carry larger loads compared to slower streams.

Front

What is erosion?

Back

Erosion is the process that picks up and moves weathered rocks and soil from one location to another.

Front

What is deposition?

Back

Deposition is the geological process where material is added to a landform or land mass, and it is considered a constructive process.

Front

What are the main types of weathering?

Back

The main types of weathering are mechanical weathering and chemical weathering.

Front

What role does wind play in shaping landscapes?

Back

Wind can erode, transport, and deposit materials, forming features like dunes and shaping the landscape.

Front

What is the difference between erosion and weathering?

Back

Weathering is the breakdown of rocks, while erosion is the movement of those weathered materials.

Front

What factors influence the rate of erosion?

Back

Factors include water flow, wind speed, vegetation cover, and the type of soil or rock.

Front

What is the significance of deposition in geological processes?

Back

Deposition contributes to the formation of new landforms and can create habitats for various organisms.
