Unit 3 Environmental Science

Front

What happens to the water cycle if the sun suddenly stops giving off heat?

Back

The water cycle would not work.

Front

What is condensation in the water cycle?

Back

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

Front

What is evaporation in the water cycle?

Back

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

Front

Which process returns carbon dioxide to the atmosphere: decomposition, photosynthesis, respiration, or combustion?

Back

Photosynthesis does not return CO2 to the atmosphere; it absorbs it.

Front

How is carbon dioxide primarily returned to the atmosphere?

Back

Through the respiration of consumers.

Front

Define 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.

Front

What role does the sun play in the water cycle?

Back

The sun provides the energy needed for evaporation.

Front

What is the difference between evaporation and transpiration?

Back

Evaporation is the process of water turning into vapor from surfaces, while transpiration is the release of water vapor from plants.

Front

What is the significance of condensation in weather formation?

Back

Condensation leads to cloud formation, which can result in precipitation.

Front

Explain the carbon cycle.

Back

The carbon cycle is the process by which carbon is exchanged among the atmosphere, land, water, and living organisms.
