What is deposition?

Answer: The process where sediments settle out of the transporting medium.

What is erosion?

Answer: The process of moving soil and rock from one location to another.

100

What force pulls objects toward the Earth?

Answer: Gravity

100

What are glaciers?

Answer: Large masses of ice that move slowly over land.

200

Name one type of weathering that involves chemical reactions.

Answer: Chemical Weathering

200

Name a natural feature formed by deposition.

Answer: Delta

200

Name one agent of erosion.

Answer: Water, wind, ice, or gravity

200

How does gravity affect the movement of water?

Answer: It causes water to flow downhill.

200

How do glaciers cause erosion?

Answer: They scrape and carry away rocks and soil as they move.

300

What type of weathering occurs when water freezes in cracks of rocks?

Answer: mechanical weathering

300

How does wind contribute to deposition?

Answer: Wind can carry and drop off sand and other materials.

300

How can animals contribute to erosion?

Answer: Burrowing animals can disturb soil and lead to erosion.

300

What is mass wasting?

Answer: The downward movement of rock and soil due to gravity.

300

What is a U-shaped valley, and how is it formed?

Answer: A valley formed by the movement of a glacier.

400

 How does vegetation help in weathering?

Answer: Roots of plants can break rocks apart.

400

What role do rivers play in deposition?

Answer: Rivers carry sediments and deposit them when they slow down.

400

What is the impact of deforestation on erosion?

Answer: It increases erosion because there are fewer roots to hold soil in place.

400

Name a landform created by gravity's effects.

Answer: Landslide

400

How do glaciers contribute to deposition?

Answer: They leave behind sediments when they melt.

500

What is the difference between mechanical and chemical weathering?

Answer: Mechanical weathering breaks rocks into smaller pieces without changing their composition, while chemical weathering changes the minerals in the rocks.

500

Explain how human activities can affect deposition.

Answer: Construction can change natural water flow, affecting where sediments deposit.

500

Describe how waves can cause erosion along coastlines.

Answer: Waves crash against rocks and cliffs, wearing them away over time.

500

 Explain how gravity influences erosion and deposition.

Answer: Gravity causes materials to move downhill, leading to erosion and deposition in lower areas.

500

 Describe the term "glacial till."

Answer: Unsorted material deposited directly by a glacier.
