Water, Carbon, & Nitrogen Cycles

Front

What is precipitation?

Back

Precipitation is the process by which water droplets fall from the atmosphere in the form of rain, snow, sleet, or hail.

Front

What is runoff?

Back

Runoff is the flow of rainwater that contributes to the movement of water in rivers and streams.

Front

What role do decomposers play in the Nitrogen Cycle?

Back

Decomposers transform nitrates back into nitrogen, returning it to the atmosphere.

Front

How do humans and plants depend on each other for gases?

Back

Humans depend on oxygen produced by plants, while plants depend on carbon dioxide exhaled by humans.

Front

What is transpiration?

Back

Transpiration is the process by which plants give off water vapor as a waste product.

Front

What is evaporation?

Back

Evaporation is the process by which water changes from a liquid to a gas, 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.

Front

What is the water cycle?

Back

The water cycle is the continuous movement of water through evaporation, condensation, precipitation, and runoff.

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 nitrogen fixation?

Back

Nitrogen fixation is the process by which nitrogen gas from the atmosphere is converted into ammonia by certain bacteria.
