Water And Carbon

Question 1

What is the water cycle?

Answer 1

The continuous movement of water on, above, and below the surface of the Earth.

Question 2

Name the processes involved in the water cycle.

Answer 2

Evaporation, condensation, precipitation, infiltration, runoff, and transpiration.

Question 3

True or False: The water cycle is a closed system.

Answer 3

True

Question 4

What is evaporation?

Answer 4

The process by which water changes from liquid to vapor.

Question 5

Fill in the blank: Water vapor cools and _______ to form clouds.

Answer 5

condenses

Question 6

What is precipitation?

Answer 6

Any form of water that falls from clouds to the Earth’s surface, including rain, snow, sleet, and hail.

Question 7

Define infiltration.

Answer 7

The process by which water soaks into the soil from the ground surface.

Question 8

What is the carbon cycle?

Answer 8

The process by which carbon is exchanged between the Earth’s atmosphere, oceans, soil, and living organisms.

Question 9

Name one human activity that increases carbon dioxide in the atmosphere.

Answer 9

Burning fossil fuels.

Question 10

True or False: Photosynthesis removes carbon dioxide from the atmosphere.

Answer 10

True

Question 11

What role do plants play in the carbon cycle?

Answer 11

Plants absorb carbon dioxide during photosynthesis and release oxygen.

Question 12

Fill in the blank: The process of _______ returns carbon to the atmosphere from living organisms.

Answer 12

respiration

Question 13

Describe carbon sequestration.

Answer 13

The process of capturing and storing atmospheric carbon dioxide.

Question 14

What is the greenhouse effect?

Answer 14

The warming of the Earth’s surface due to the trapping of heat by greenhouse gases.

Question 15

How do oceans contribute to the carbon cycle?

Answer 15

Oceans absorb carbon dioxide from the atmosphere and store it in water and marine organisms.

Question 16

What is the significance of the carbon sink?

Answer 16

It refers to natural systems that absorb more carbon than they release, helping to mitigate climate change.

Question 17

True or False: Deforestation decreases the amount of carbon dioxide in the atmosphere.

Answer 17

False

Question 18

What process releases carbon stored in fossil fuels?

Answer 18

Combustion.

Question 19

Fill in the blank: The _______ cycle is essential for regulating the Earth’s climate.

Answer 19

carbon

Question 20

What are the four main reservoirs in the carbon cycle?

Answer 20

The atmosphere, biosphere, hydrosphere, and lithosphere.

Question 21

Name a natural process that releases carbon dioxide.

Answer 21

Volcanic eruptions.

Question 22

What is transpiration?

Answer 22

The process by which water is absorbed by plants and released as vapor through their leaves.

Question 23

True or False: The water cycle has no impact on weather patterns.

Answer 23

False

Question 24

What is condensation?

Answer 24

The process by which water vapor cools and changes back into liquid water.

Question 25

Fill in the blank: Water that flows over the surface of the land is called _______.

Answer 25

runoff

Question 26

What is the main driver of the water cycle?

Answer 26

The sun's energy.

Question 27

Which gas is primarily responsible for the greenhouse effect?

Answer 27

Carbon dioxide.

Question 28

How does agriculture affect the carbon cycle?

Answer 28

It can increase carbon emissions through soil disturbance and fertilizer use.

Question 29

What is the role of decomposers in the carbon cycle?

Answer 29

Decomposers break down dead organic matter, releasing carbon back into the soil and atmosphere.

Question 30

True or False: The carbon cycle is only affected by natural processes.

Answer 30

False

Question 31

What is the impact of climate change on the water cycle?

Answer 31

It causes changes in precipitation patterns, increased evaporation, and altered water distribution.
