Biogeochemical Cycles

Front

What is a biogeochemical cycle?

Back

A biogeochemical cycle is the movement of elements and compounds through biological, geological, and chemical processes in the environment.

What is the carbon cycle?

Back

The carbon cycle is the movement of carbon through different ecosystems, including processes like photosynthesis, respiration, and decomposition.

Front

What role do phytoplankton play in the carbon cycle?

Back

Phytoplankton use carbon dioxide dissolved in the ocean for photosynthesis, converting it into organic matter.

Front

What is the hydrologic cycle?

Back

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

Front

What happens during evaporation?

Back

Evaporation is the process where liquid water is transformed into water vapor, usually from the surface of oceans, lakes, and rivers.

Front

What is transpiration?

Back

Transpiration is the process by which water is absorbed by plant roots and then released as vapor through pores in leaves.

Front

What is evapotranspiration?

Back

Evapotranspiration is the combined process of evaporation from the land and transpiration from plants.

Front

What are fossil fuels?

Back

Fossil fuels are carbon-rich geological deposits formed from the remains of dead plants and animals, including coal, oil, and natural gas.

Front

What is the role of clouds in the hydrologic cycle?

Back

Clouds store water in the atmosphere and release it as precipitation.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of carbon dioxide and water.
