Water Cycle Flashcard

Front

What is 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 again through evaporation, condensation, precipitation, and runoff.

Front

Where does the energy for the water cycle come from?

Back

The sun.

Front

What is evaporation?

Back

Evaporation is the process where liquid water changes into water vapor or gas, usually due to heat from the sun.

Front

What is condensation?

Back

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

Front

What is precipitation?

Back

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

Front

What is runoff?

Back

Runoff is the flow of water, usually from rain, that moves across the ground and into rivers, lakes, and oceans.

Front

What is movement in the context of the water cycle?

Back

Movement refers to the change in position or location of water as it travels through the water cycle.

Front

What is energy in the context of the water cycle?

Back

Energy is what is needed to do work or cause change, such as the energy from the sun that drives the water cycle.

Front

How does the sun affect the water cycle?

Back

The sun provides the energy needed for evaporation, which is the first step in the water cycle.

Front

What happens during evaporation?

Back

During evaporation, water from oceans, rivers, and lakes is heated by the sun and turns into vapor, rising into the atmosphere.
