water and nitrogen cycles

Front

What is condensation in the water cycle?

Back

Condensation is the process where water vapor in the air cools and changes into liquid water, forming clouds.

Front

What percentage of the Earth's atmosphere is nitrogen?

Back

78% of the Earth's atmosphere is nitrogen.

Front

Can organisms absorb nitrogen gas directly from the atmosphere?

Back

No, organisms cannot absorb nitrogen gas directly from the atmosphere.

Front

What is the primary source of energy for the water cycle?

Back

The sun is the primary source of energy for the water cycle.

Front

List the main processes of the water cycle in order: evaporation, condensation, precipitation, transpiration.

Back

1: Evaporation, 2: Condensation, 3: Precipitation, 4: Transpiration.

Front

What is evaporation in the water cycle?

Back

Evaporation is the process where liquid water is heated by the sun and changes into water vapor.

Front

What role do plants play in the water cycle?

Back

Plants contribute to the water cycle through transpiration, where they release water vapor into the air.

Front

What is precipitation in the water cycle?

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

How does nitrogen fixation occur?

Back

Nitrogen fixation occurs when certain bacteria convert nitrogen gas from the atmosphere into ammonia, which plants can use.

Front

What is the difference between the water cycle and the nitrogen cycle?

Back

The water cycle describes the movement of water through evaporation, condensation, and precipitation, while the nitrogen cycle describes the transformation and movement of nitrogen through the environment.
