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.

What does runoff mean?

Back

Runoff refers to water that flows over the ground surface and eventually makes its way to rivers, lakes, and oceans.

Front

What is the main energy source for the water cycle?

Back

The sun is the main energy source for the water cycle, providing the heat necessary for evaporation.

Front

What does condensation mean?

Back

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

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 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 are the different forms of precipitation?

Back

The different forms of precipitation include rain, snow, sleet, and hail.

Front

What is the role of the sun in 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 the process of evaporation?

Back

During evaporation, water absorbs heat and changes from a liquid state to a gaseous state (water vapor).

Front

How does water vapor become clouds?

Back

Water vapor cools in the atmosphere and condenses into tiny water droplets, which cluster together to form clouds.
