The water cycle and carbon cycle review

Front

What is the water cycle?

Back

The water cycle is the continuous process by which water moves from the Earth's surface to the atmosphere and back, involving processes like evaporation, condensation, precipitation, and runoff.

Front

Define evaporation.

Back

Evaporation is the process by which water changes from a liquid to a gas (water vapor) 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 precipitation?

Back

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

Front

What is runoff?

Back

Runoff is the flow of water that occurs when excess water from rain or melting snow flows over the land and returns to rivers, lakes, and oceans.

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

Define combustion.

Back

Combustion is a chemical reaction that occurs when a substance (usually a fuel) reacts with oxygen to produce heat and light, releasing carbon dioxide as a byproduct.

Front

What is respiration in the context of the carbon cycle?

Back

Respiration is the process by which living organisms break down sugars to release energy, producing carbon dioxide as a waste product.

Front

What is decomposition?

Back

Decomposition is the process by which dead organic matter is broken down by bacteria, fungi, and other decomposers, releasing carbon back into the environment.

Front

How do plants contribute to the carbon cycle?

Back

Plants absorb carbon dioxide from the atmosphere during photosynthesis, using it to produce sugars and oxygen.
