DPHS 1.2 Carbon and Water Cycles

Florida is known as the "Sunshine State" because we have high amounts of sunlight exposure. How does all this sunlight affect the water cycle?

• The water cycle will be more active due to higher evaporation rates

• The water cycle will be less active due to lower evaporation rates

• The water cycle will be unaffected

• The water cycle will be more active due to higher percolation.

A local forest is infected with a disease that prevents tree roots from absorbing water and

transporting it throughout the plant. How will this affect the water cycle?

• Transpiration will decrease; evaporation will be unaffected

• Transpiration will increase; evaporation will increase

• Transpiration will be unaffected; evaporation will be unaffected

• Transpiration will be unaffected; evaporation will decrease

Combustion is a process of the carbon cycle where humans burn fossil fuels to produce energy. Which of the following statements correctly describes a consequence of burning fossil fuels? (hint: where does the carbon end up?)

• Humans burning fossil fuels will lead to increased levels of carbon dioxide gas in the atmosphere.

• If humans decrease their reliance on combustion, underground fossil fuels will also decrease.

• Increased combustion of fossil fuels will encourage higher rates of respiration.

• Decreased combustion of fossil fuels will lead to more organic carbon for photosynthetic

  organisms like plants.

The graph shows how temperature will be affected by global warming. Which statement best describes how global warming will likely affect the water cycle?

• A decrease in global land and ocean temperatures will result in lower rates of evaporation.

• A decrease in global land and ocean temperatures will result in higher rates of

  precipitation.

• An increase in global land and ocean temperatures will result in higher rates of

  evaporation.

• An increase in global land and ocean temperatures will result in lower rates of

  condensation.

Combustion is a process of the carbon cycle where humans burn what type of carbon source?

• Fossil fuels

• Organics

• Atmospheric

• Photosynthesis

Fossil fuels are a type of carbon source found underground. Fossil fuels were originally what?

• Living organisms that died millions of years ago

• Oil

• Carbon dioxide in the air

• Living organisms that died recently

Organic carbon is found where?

• Deep underground

• In living things

• In the air

• In cars and factories

Atmospheric carbon is found where?

• In the air surrounding Earth

• In living things

• Deep underground

• In cars and factories

Dermestid beetles are a type of insect that help the process of decay by eating and breaking down dead animals. If pesticides from a local farm caused a decrease in the local dermestid beetle population, how would the carbon cycle be affected?

• Carbon in the atmosphere would increase

• Carbon in the soil would decrease

• Carbon in the soil would increase

• Carbon would not be affected

As of 2024, the human population is over 8 billion! If humans keep growing in number, what is a likely impact on the carbon cycle?

• Carbon in the atmosphere will increase due to increased reliance on fossil fuels

• Carbon in the soil would decrease due to less decay

• With more humans breathing, carbon in the atmosphere will decrease

• Underground fossil fuel levels will increase due to increased reliance on combustion
