The Water Cycle: Water’s Endless Journey Across Planet Earth

The video explains the water cycle, starting with evaporation where water from oceans, lakes, and rivers turns into vapor and rises into the air. This vapor cools and condenses into clouds, which are made of tiny water droplets. Clouds can hold a lot of water, and when droplets become too heavy, they fall as precipitation like rain or snow. This water collects in bodies of water and underground reservoirs, restarting the cycle. The video highlights the uneven distribution of water across the planet.

What happens to water molecules during evaporation?

• They become tightly packed together.

• They form visible droplets.

• They turn into ice crystals.

• They break away and spread out in the air.

Why do clouds appear light and fluffy?

• Because they are filled with feathers.

• Because they are made of air.

• Because they are made of ice.

• Because they are made of tiny water droplets.

What causes water droplets in clouds to fall as precipitation?

• They turn into vapor.

• They evaporate.

• They become too light.

• They become too densely packed.
