Water Cycle Concepts and Processes

The video explains the water cycle, starting with evaporation where the sun heats water turning it into vapor. This vapor rises, cools, and condenses into clouds. When droplets in clouds become heavy, they fall as precipitation. This cycle repeats, ensuring water availability for all life forms.

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

• To create clouds

• To warm the water and turn it into vapor

• To cool down the water

• To make rain fall

What happens to water when it evaporates?

• It turns into ice

• It becomes a solid

• It changes into an invisible gas

• It remains as liquid

Why does water vapor rise into the sky?

• Because it is lighter than liquids

• Because it is heavier than air

• Because it is pushed by the wind

• Because it is attracted by the sun

What is the process called when water vapor turns into tiny droplets?

• Collection

• Evaporation

• Precipitation

• Condensation

What are clouds primarily made of?

• Dust particles

• Tiny water droplets

• Air molecules

• Ice crystals

What causes raindrops to fall from clouds?

• Wind

• Gravity

• Sunlight

• Temperature

How many tiny water droplets make up a single raindrop?

• One million

• One thousand

• One hundred

• One billion

What is the term for water falling from the sky as rain, snow, or hail?

• Evaporation

• Condensation

• Precipitation

• Collection

What happens during the collection stage of the water cycle?

• Water forms clouds

• Water turns into vapor

• Water falls as rain

• Water is stored in oceans and lakes

Which process is the opposite of evaporation?

• Condensation

• Precipitation

• Collection

• Sublimation
