The process of moving pieces of rock, soil, or the remains of plants and animals is called:

• Deposition

• Weathering

• Erosion

• Mass movement

The process where agents of erosion drop or lay down sediment is called:

• Erosion

• Transportation

• Deposition

• Weathering

What is the primary force driving mass movement?

• Wind

• Water

• Gravity

• Ice

The process by which wind removes surface materials is called:

• Abrasion

• Deflation

• Deposition

• Transportation

Wind, water, and ice can cause erosion by carrying particles that rub or scrape against exposed rock. This process is known as:

• Deflation

• Deposition

• Abrasion

• Weathering

Sand dunes are landforms primarily created by:

• Water deposition

• Glacial erosion

• Wind deposition

• Mass movement

Loess deposits are formed from:

• Large rocks deposited by glaciers.

• Sand piled up by wind.

• Fine, wind-deposited sediments.

• Sediment deposited by fast-flowing rivers.

Which of the following is a rapid type of mass movement?

• Creep

• Slump

• Soil formation

• Weathering

The continuous cycle that wears down and builds up Earth's surface involves:

• Only erosion and deposition.

• Only weathering and erosion.

• Weathering, erosion, transportation, and deposition.

• Only transportation and deposition.

Sediment is best described as:

• Solid rock formations.

• Dissolved minerals in water.

• Moving pieces of rock, soil, or organic remains.

• The force that moves material downhill.
