Weathering, Erosion, Deposition and landforms

Front

What are sand dunes?

Back

Mounds of sand formed by the wind that accumulate when the wind slows down upon hitting an object.

Front

How do plants help in erosion control?

Back

Plants can slow erosion by anchoring their roots into the ground, stabilizing the soil.

Front

What is acid rain?

Back

Acid rain is precipitation that contains high levels of sulfuric or nitric acids, which can cause chemical weathering of rocks.

Front

What is physical weathering?

Back

Physical weathering is the process that breaks down rocks into smaller pieces without changing their chemical composition, often resulting in rounded rocks.

Front

What is an example of physical weathering?

Back

An animal burrowing into the ground is an example of physical weathering.

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.

Front

What is deposition?

Back

Deposition is the process where eroded materials are dropped off in a new location, forming new landforms.

Front

What is abrasion in the context of weathering?

Back

Abrasion is the process of wearing down rocks through friction and impact, often caused by wind or water carrying particles.

Front

What is frost wedging?

Back

Frost wedging is a type of physical weathering that occurs when water seeps into cracks in rocks, freezes, and expands, causing the rocks to break apart.

Front

What are the effects of chemical weathering?

Back

Chemical weathering alters the chemical composition of rocks, often leading to the formation of new minerals and soil.
