Back

Any type of liquid or solid water that falls to Earth's surface, such as rain, snow, sleet, or hail.

Front

What is evaporation?

Back

The process by which water changes from a liquid to a gas or vapor, usually due to heat.

Front

What is condensation?

Back

The process by which water vapor cools and changes back into liquid water, forming clouds.

Front

What is the water cycle?

Back

The continuous movement of water on, above, and below the surface of the Earth, involving processes like evaporation, condensation, and precipitation.

Front

What is weather?

Back

The condition of the Earth's atmosphere at a certain time and place, including temperature, humidity, and precipitation.

Front

What is climate?

Back

The average weather conditions in a particular area over a long period of time.

Front

What is runoff?

Back

Water that flows over the ground surface and returns to rivers, lakes, and oceans after precipitation.

Front

What is the most abundant form of water in the water cycle?

Back

Liquid salt water, as it makes up about 97% of the Earth's water.

Front

What is the role of the sun in the water cycle?

Back

The sun provides the energy needed for evaporation, driving the water cycle.

Front

What is humidity?

Back

The amount of water vapor present in the air, which can affect weather conditions.
