Back

The nitrogen cycle is the process in which nitrogen circulates and is recycled in the environment.

Front

What is the water cycle?

Back

The water cycle is the movement of water on, above, or below the surface of the Earth.

Front

What role do plants play in the carbon cycle?

Back

Plants absorb carbon dioxide during photosynthesis, converting it into oxygen and glucose.

Front

What is evaporation in the water cycle?

Back

Evaporation is the process where liquid water is transformed into water vapor.

Front

What is condensation in the water cycle?

Back

Condensation is the process where water vapor cools and changes back into liquid water, forming clouds.

Front

What is the role of decomposers in the nitrogen cycle?

Back

Decomposers break down dead organisms, returning nitrogen to the soil.

Front

What is biogeochemical cycling?

Back

Biogeochemical cycling refers to the movement of elements and compounds through biological, geological, and chemical processes.
