Water cycle

The video explains the origin and recycling of Earth's water through the water cycle. It describes how water evaporates, condenses, and precipitates, forming clouds and falling as rain, hail, or snow. The cycle continues as water collects in bodies of water and returns to the ocean.

What natural process has been recycling Earth's water for billions of years?

• The oxygen cycle

• The water cycle

• The nitrogen cycle

• The carbon cycle

What happens to water when the sun heats it up?

• It turns into ice

• It becomes water vapor

• It falls as rain

• It forms clouds

What is the process called when water vapor cools and forms droplets?

• Condensation

• Sublimation

• Precipitation

• Evaporation

What is it called when water falls from clouds as rain, hail, or snow?

• Condensation

• Infiltration

• Precipitation

• Evaporation

Where does rainwater eventually collect before returning to the ocean?

• In glaciers

• In waterfalls, lakes, and rivers

• In underground reservoirs

• In the atmosphere
