What is a biogeochemical cycle?

Back

A biogeochemical cycle is the movement of elements and compounds through living organisms and the physical environment, involving biological, geological, and chemical processes.

What are the main components of the water cycle?

Back

The main components of the water cycle are evaporation, condensation, precipitation, and collection.

What is evaporation in the water cycle?

Back

Evaporation is the process where water changes from a liquid to a gas, usually due to heat from the sun.

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.

What is precipitation in the water cycle?

Back

Precipitation is any form of water that falls from clouds to the Earth's surface, including rain, snow, sleet, and hail.

How do plants obtain carbon?

Back

Plants obtain carbon through the process of photosynthesis, where they absorb carbon dioxide from the atmosphere.

Front

What role do decomposers play in biogeochemical cycles?

Back

Decomposers break down dead organisms, returning nutrients to the soil and making them available for plants.

Front

What is the carbon cycle?

Back

The carbon cycle is the process by which carbon is exchanged among the atmosphere, land, water, and living organisms.

Front

What is the significance of fossil fuels in the carbon cycle?

Back

Fossil fuels are formed from the remains of ancient organisms and store carbon; when burned, they release carbon dioxide into the atmosphere.

Where is most of Earth's freshwater found?

Back

Most of Earth's freshwater is found in glaciers and ice caps.
