Biogeochemical Cycles (Bio)

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 such as evaporation, condensation, precipitation, and infiltration.

Front

What is precipitation?

Back

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

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll, producing oxygen and glucose.

Front

What is denitrification?

Back

Denitrification is the process by which bacteria convert nitrates in the soil back into nitrogen gas, releasing it into the atmosphere.

Front

What is the role of plants in the carbon cycle?

Back

Plants absorb carbon dioxide from the atmosphere during photosynthesis, which helps to reduce the amount of carbon in the atmosphere.

Front

What are the main forms of precipitation?

Back

The main forms of precipitation include rain, snow, sleet, and hail.

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 from the sun.

Front

What is transpiration?

Back

Transpiration is the process by which water is absorbed by plant roots, moves through plants, and is released as water vapor through pores in leaves.

Front

What is the significance of the nitrogen cycle?

Back

The nitrogen cycle is crucial for converting nitrogen from the atmosphere into forms that plants and animals can use, thus supporting life.

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.
