What are the main components of the water cycle?

Back

The main components of the water cycle include evaporation, condensation, precipitation, and infiltration.

How does phosphorus move from water to soil?

Back

Phosphorus moves from water to soil primarily through the process of weathering.

What is transpiration?

Back

Transpiration is the process by which plants lose water vapor through small openings in their leaves called stomata.

What is the role of carbon in the environment?

Back

Carbon is essential for life and is found in all living organisms; it is stored in fossil fuels, the ocean, and the wood of trees.

Front

What is the carbon cycle?

Back

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

Front

What is the nitrogen cycle?

Back

The nitrogen cycle is the process by which nitrogen is converted between its various chemical forms, including fixation, nitrification, and denitrification.

Front

What is evaporation?

Back

Evaporation is the process by which water changes from a liquid to a gas or vapor, usually due to heat.

Front

What is condensation?

Back

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