Weathering

Question 1

What is weathering in geography?

Answer 1

Weathering is the process of breaking down rocks and minerals into smaller pieces through various physical, chemical, and biological processes.

Question 2

True or False: Weathering is the same as erosion.

Answer 2

False: Weathering is the breakdown of materials, while erosion involves the movement of those materials.

Question 3

Fill in the blank: The two main types of weathering are __________ and __________.

Answer 3

physical, chemical

Question 4

What type of weathering involves the alteration of the chemical composition of rocks?

Answer 4

Chemical weathering

Question 5

Which type of weathering is characterized by the physical breakdown of rocks without changing their chemical composition?

Answer 5

Physical weathering

Question 6

What is an example of physical weathering?

Answer 6

Frost wedging, where water freezes in cracks of rocks and expands, causing the rocks to break apart.

Question 7

Name one factor that influences the rate of weathering.

Answer 7

Climate, rock type, vegetation, or surface area.

Question 8

True or False: Biological weathering can only occur in forested areas.

Answer 8

False: Biological weathering can occur in various environments where organisms interact with rocks.

Question 9

What is the role of carbonic acid in chemical weathering?

Answer 9

Carbonic acid, formed from carbon dioxide and water, helps dissolve minerals like calcite in limestone.

Question 10

Fill in the blank: __________ weathering occurs when rocks are broken down by the action of living organisms.

Answer 10

Biological

Question 11

What is the process called when rocks are worn away by wind, water, or ice?

Answer 11

Erosion

Question 12

Multiple choice: Which of the following is NOT a type of weathering? A) Mechanical B) Chemical C) Thermal D) Erosional

Answer 12

D) Erosional

Question 13

What is exfoliation in the context of physical weathering?

Answer 13

Exfoliation is the process where outer layers of rock peel away due to temperature changes.

Question 14

True or False: Chemical weathering is faster in warm and wet climates.

Answer 14

True

Question 15

What is the primary agent of chemical weathering?

Answer 15

Water

Question 16

Name a common product of weathering.

Answer 16

Soil

Question 17

Fill in the blank: The breakdown of rocks into smaller particles contributes to the formation of __________.

Answer 17

Sediments

Question 18

Which process can lead to the formation of caves?

Answer 18

Chemical weathering, particularly through the dissolution of limestone.

Question 19

What is the significance of weathering in the rock cycle?

Answer 19

Weathering is essential for breaking down rocks, leading to soil formation and the recycling of minerals.

Question 20

True or False: Weathering can occur in both dry and wet environments.

Answer 20

True

Question 21

What is a common result of freeze-thaw weathering?

Answer 21

Cracking and fragmentation of rocks.

Question 22

Multiple choice: Which type of rock is most susceptible to chemical weathering? A) Igneous B) Metamorphic C) Sedimentary D) All of the above

Answer 22

C) Sedimentary

Question 23

What type of weathering can occur due to acid rain?

Answer 23

Chemical weathering

Question 24

Fill in the blank: The action of roots growing into cracks in rocks is an example of __________ weathering.

Answer 24

Biological

Question 25

What is the difference between weathering and mass wasting?

Answer 25

Weathering is the breakdown of rocks, while mass wasting refers to the movement of materials down a slope due to gravity.
