Biogeochemical Cycles Flashcard Practice

Front

What is the water cycle?

Back

The water cycle is the continuous process by which water moves from the Earth's surface to the atmosphere and back, involving processes such as evaporation, condensation, precipitation, and runoff.

Front

What happens to the water cycle if one part changes?

Back

If one part of the water cycle changes, all parts of the water cycle can also change.

Front

What is the impact of burning fossil fuels on atmospheric carbon levels?

Back

Burning fossil fuels increases the amount of carbon in the atmosphere.

Front

What process do animals use to return carbon to the atmosphere?

Back

Animals return carbon to the atmosphere through respiration.

Front

What is runoff in the context of the water cycle?

Back

Runoff is the flow of water, from rain or melting snow, that moves across the ground and into bodies of water.

Front

What happens to runoff when precipitation decreases?

Back

When precipitation decreases, there will be less runoff.

Front

How does decreased runoff affect lakes?

Back

Decreased runoff can lead to smaller lakes due to reduced water inflow.

Front

What must happen for nitrogen to be usable by plants?

Back

Nitrogen must be fixed before it can be used by plants.

Front

What is nitrogen fixation?

Back

Nitrogen fixation is the process of converting nitrogen gas from the atmosphere into a form that plants can absorb and use.

Front

What role do plants play in the carbon cycle?

Back

Plants absorb carbon dioxide from the atmosphere during photosynthesis, which is a key part of the carbon cycle.
