The Water Cycle

The Journey of Water

The water cycle describes how water moves around our planet in a never-ending loop!

Steps in the Water Cycle

  • Evaporation: The sun heats up water, turning it into vapor.
  • Condensation: Water vapor cools and forms clouds.
  • Precipitation: Water falls as rain, snow, or hail.
  • Collection: Water gathers in rivers, lakes, and oceans.

Why Is the Water Cycle Important?

The water cycle provides fresh water for people, plants, and animals, and it helps shape our weather.

Real-World Connections

When you see puddles disappear after rain, that's evaporation at work!

Examples

  • Clouds forming after a hot day.

  • Rain filling up a pond.

In a Nutshell

The water cycle moves water through the environment, keeping Earth hydrated.

Key Terms

Evaporation
When liquid water turns into vapor.
Condensation
When vapor cools and turns into droplets.
Precipitation
Water falling from the sky as rain, snow, or hail.
