Why is the Water Cycle Essential for Life on Earth?

The water cycle is super important for life on Earth! It helps keep everything balanced and supports ecosystems.

Key Parts of the Water Cycle:

  1. Evaporation: About 80% of the water vapor in the air comes from the ocean. The rest comes from lakes and rivers.

  2. Condensation: When water vapor cools down, it turns back into tiny water droplets and forms clouds. These clouds can have millions of those droplets!

  3. Precipitation: Every year, around 505,000 cubic kilometers of water falls from the sky as precipitation. This helps refill our freshwater sources.

Why the Water Cycle Matters:

  • Supports Ecosystems: Freshwater makes up only about 2.5% of all the water on Earth. This water is essential for drinking, farming, and many industries.

  • Helps Wildlife: Wetlands are areas that hold water and cover about 6% of the Earth's surface. They provide homes for many different animals and plants, and they also help clean our water naturally.

  • Controls the Weather: The water cycle plays a big role in controlling temperatures and weather patterns. This affects both local regions and the whole planet.

Interesting Facts:

  • About 97% of the Earth's water is salty and found in oceans.

  • Each person needs about 2 to 4 liters of fresh water every day to stay healthy.

  • Around 505 billion tonnes of water evaporate from the oceans each year in the global water cycle.

Learning about the water cycle shows us how crucial it is for keeping our planet balanced and for supporting all life.
