What is the water cycle?

Back

The water cycle is the continuous movement of water within the Earth and atmosphere, involving processes such as evaporation, condensation, precipitation, and runoff.

Front

What happens during condensation in the water cycle?

Back

During condensation, water vapor in the air cools and changes into liquid water, forming clouds.

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 role do bacteria play in nutrient cycles?

Back

Bacteria decompose organic matter, recycling nutrients back into the ecosystem, and can also fix nitrogen, making it available for plants.

Front

What is the phosphorus cycle?

Back

The phosphorus cycle is the process by which phosphorus moves through the lithosphere, hydrosphere, and biosphere, primarily through the weathering of rocks and uptake by organisms.

Front

How do nitrogen-fixing bacteria contribute to the nitrogen cycle?

Back

Nitrogen-fixing bacteria convert atmospheric nitrogen (N2) into ammonia (NH3), which can be used by plants.

Front

What is deposition in the context of the water cycle?

Back

Deposition is the process where water vapor changes directly into solid ice, such as frost, without becoming liquid first.

Front

What is evaporation?

Back

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

Front

What is transpiration?

Back

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

Front

What is runoff?

Back

Runoff is the flow of water, from rain or melting snow, that moves across the ground and returns to bodies of water.
