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 happens to salt water when the sun heats it?

Back

Salt water will evaporate and become fresh water vapor.

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 in the water cycle?

Back

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

Front

What causes shadows to move during the day?

Back

Shadows move due to the rotation of the Earth, which changes the position of the sun in the sky.

Front

What are the phases of the moon?

Back

The phases of the moon are the different appearances of the moon as seen from Earth, including new moon, crescent, first quarter, gibbous, and full moon.

Front

What is solar energy?

Back

Solar energy is the energy from the sun that is harnessed for various processes, including the evaporation of water.

Front

What is precipitation?

Back

Precipitation is any form of water, liquid or solid, that falls from the atmosphere to the Earth's surface, such as rain, snow, sleet, or hail.

Front

How does the moon affect tides?

Back

The moon's gravitational pull affects the Earth's oceans, causing tides to rise and fall.

Front

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

Back

The sun provides the energy needed for evaporation, which is a key process in the water cycle.
