Passage: The Water Cycle

Water is one of the most important natural resources on Earth. It is constantly moving around our planet through a process called the water cycle. This cycle has four main stages: evaporation, condensation, precipitation, and collection.

When the Sun heats oceans, rivers, and lakes, water turns into vapor and rises into the air — this is called evaporation. As the water vapor moves higher, it cools and changes back into tiny water droplets, forming clouds. This process is known as condensation.

When these droplets combine and become heavy, they fall back to Earth as precipitation — in the form of rain, snow, or hail. Finally, the water collects again in rivers, lakes, and oceans, completing the cycle. This continuous movement of water helps maintain life on Earth by providing fresh water for plants, animals, and humans.

Questions:

1. What are the four main stages of the water cycle?
2. What happens during evaporation?
3. What is condensation?
4. In what forms can precipitation occur?
5. Why is the water cycle important for life on Earth?
