Water Smart: The Sun, Water Cycle, & Climate - Condensation

The video explains how clouds form from tiny water droplets or ice crystals when air cannot hold more water vapor. It describes how clouds vary in shape, size, and color, and their role in weather by moving moisture and blocking sunlight. Condensation occurs when air is saturated with water vapor or cooled, forming dew and frost. Everyday examples include condensation on cold surfaces like glasses and refrigerators.

What are clouds primarily composed of?

• Dust particles

• Oxygen molecules

• Tiny water droplets or ice crystals

• Carbon dioxide

How does condensation occur in the air?

• By adding more oxygen to the air

• By increasing the air temperature

• When air cannot hold any more water vapor

• By reducing the amount of water vapor

What is one way clouds help the Earth?

• They increase the Earth's temperature

• They block harmful UV rays

• They produce oxygen

• They transport moisture to dry areas

What is dew?

• Water droplets on grass or cars

• A form of precipitation

• Ice crystals on windows

• A type of cloud

Why do water droplets form on a cold glass?

• The glass absorbs water from the air

• The glass releases water

• The air around the glass cools and condenses

• The glass is porous
