The video explains the water cycle, highlighting that Earth's water is ancient and continuously circulates. It covers the roles of oceans, evaporation, condensation, precipitation, and collection in maintaining Earth's freshwater supply. The cycle begins with evaporation, where water turns into vapor, followed by condensation forming clouds. Precipitation returns water to Earth as rain, hail, or snow, and collection completes the cycle by storing water in various bodies and groundwater.

What is the primary role of oceans in the water cycle?

• They provide drinking water.

• They help replenish fresh water sources.

• They store fresh water.

• They prevent evaporation.

During evaporation, what happens to the water on the Earth's surface?

• It turns into ice.

• It becomes vapor and enters the atmosphere.

• It remains unchanged.

• It turns into salt.

What process involves plants losing water from their leaves?

• Condensation

• Collection

• Precipitation

• Transpiration

What forms when water vapor cools and condenses in the atmosphere?

• Rain

• Clouds

• Snow

• Hail

Which of the following is NOT a type of precipitation?

• Rain

• Snow

• Hail

• Fog

What happens to water during the collection stage of the water cycle?

• It evaporates into the atmosphere.

• It forms clouds.

• It gathers in bodies of water or seeps into the ground.

• It turns into ice.

Where does most of the runoff water eventually end up?

• In the soil

• In the oceans

• In the clouds

• In the atmosphere
