Weathering Quiz- Chapter 2A

What is the geologic process that breaks down rock on Earth's surface?

• Weathering

• Erosion

• Deposition

What is 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, are deposited, or dropped in a new location is called?

• 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

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

• Carbonic acid

• Lichens and mosses

• Abrasion

Water can seep into the tiny cracks of many rocks. When the temperature drops, this water freezes and expands, breaking the rocks apart. What type of mechanical weathering is this?

• Root wedging

• Frost wedging

• Oxidation

• Mass movement

These rocks were made smooth by wind blowing smaller rock particles across their surface. This is an example of:

• ice wedging

• chemical weathering

• acid rain

• abrasion

These rocks were broken apart due to the continuous freeze/thaw cycle of water in the cracks of the rocks. This is an example of:

• ice wedging

• acid rain

• permeability

• abrasion

How is mechanical weathering different from chemical weathering?

• Chemical weathering happens over a much shorter time frame than mechanical weathering.

• Chemical weathering changes the chemical composition of rocks; mechanical weathering does not.

• Chemical weathering occurs only in tropical climates; mechanical weathering occurs only in cool climates.

• Chemical weathering occurs only in the mountains; mechanical weathering occurs only on flat land.
