Unit 1 Test 2

Front

What is a delta?

Back

A delta is a landform that forms at the mouth of a river where it meets a body of water, created by the deposition of sediment carried by the river.

Front

How is a delta formed?

Back

A delta is formed by the constructive process of deposition, where sediment is deposited as the river slows down.

Front

What is erosion?

Back

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

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 erosion affect landforms?

Back

Erosion can cause landforms to disappear or change shape over time.

Front

How does deposition affect landforms?

Back

Deposition can cause landforms to grow larger or change shape as new materials are added.

Front

What is coastal erosion?

Back

Coastal erosion is the process where coastlines are eroded by wave action, currents, and tides, leading to the loss of land.

Front

What are groins?

Back

Groins are structures built out into the water to prevent beach erosion by trapping sand.

Front

What is the role of technology in controlling erosion?

Back

Technology can help control erosion through methods like building groins, seawalls, and using sandbags.

Front

What is the difference between erosion and weathering?

Back

Erosion involves the movement of soil and rock, while weathering is the breaking down of rocks and minerals without movement.
