Cycles of Matter

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. It includes processes like photosynthesis, respiration, and decomposition.

What role does photosynthesis play in the carbon cycle?

Back

Photosynthesis is the process by which plants convert carbon dioxide and sunlight into glucose and oxygen, thus removing carbon dioxide from the atmosphere.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy, producing carbon dioxide and water as byproducts.

Front

What is the water cycle?

Back

The water cycle is the continuous movement of water on, above, and below the surface of the Earth, involving processes like evaporation, condensation, precipitation, and transpiration.

Front

What processes are involved in the water cycle?

Back

The main processes of the water cycle include evaporation, condensation, precipitation, and transpiration.

Front

What is evaporation?

Back

Evaporation is the process by which liquid water is transformed into water vapor, usually due to heat from the sun.

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 the atmosphere to the Earth's surface.

Front

What is transpiration?

Back

Transpiration is the process by which water is absorbed by plants and then released as water vapor through small openings in their leaves.

Front

How do human activities affect the carbon cycle?

Back

Human activities like burning fossil fuels and deforestation increase carbon dioxide levels in the atmosphere, disrupting the natural carbon cycle.
