science erosion

The geologic process of breaking down rock on Earth's surface.

• weathering

• erosion

• deposition

The geologic process by which water, wind, ice, and gravity move pieces of rock or soil.

• weathering

• erosion

• deposition

The geologic process by which eroded sediments settle and are deposited or dropped in a new location.

• weathering

• erosion

• deposition

Rock that is physically broken down into smaller pieces but the chemical composition of the minerals within the rock does not change.

• mechanical or physical weathering

• chemical weathering

• erosion

• deposition

Small, solid pieces of rock created by mechanical or chemical weathering.

• sediment

• mass movement

• crumbs

• deposition

Which of the following are examples of mechanical or physical weathering? Check all that apply.

• frost wedging

• root wedging

• exfoliation

• oxidation

• abrasion

Which of the following are examples of chemical weathering? Check all that apply.

• oxidation

• frost wedging

• carbonation

• dissolution

• hydrolysis

What is the main cause of erosion?

• abrasion

• deposition

• running water

• mass movement

Which of the following is the destructive force that responsible for mass movement like landslides, mudflow, creep, and slump?

• weathering

• erosion

• deposition

Water is able to seep into the tiny cracks of many rocks. When the temperature drops, this water freezes and expands which then breaks the rocks apart. What kind of mechanical weathering is this?

• root wedging

• frost wedging

• oxidation

• mass movement
