STAAR Review Water Cycle

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, involving processes like evaporation, condensation, and precipitation.

Front

What is evaporation?

Back

Evaporation is the process by which water changes from a liquid to a gas, usually due to heat from the sun.

Front

What is condensation?

Back

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

Front

What is precipitation?

Back

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

Front

What is runoff?

Back

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

Front

Why is runoff important?

Back

Runoff is important because it returns water to other locations on Earth, helping to replenish water sources.

Front

What role does the sun play in the water cycle?

Back

The sun provides the heat necessary for evaporation, driving the water cycle.

Front

What happens during the process of evaporation?

Back

During evaporation, water absorbs heat and transforms from a liquid state into water vapor.

Front

What is the difference between evaporation and condensation?

Back

Evaporation is the process of water turning into vapor, while condensation is the process of vapor turning back into liquid water.

Front

What is dew?

Back

Dew is moisture that forms on surfaces when water vapor condenses into liquid water, often seen in the morning.
