364 - What is the water cycle, and how does it affect ecosystems?

The water cycle is like a big circle that water goes through. Here's how it works:

1. The sun heats the water in the ocean, lakes, and rivers, turning it into water vapor (like steam).
2. This water vapor rises into the air and forms clouds.
3. When the clouds get too heavy with water, the water falls back to the Earth as rain or snow.
4. The rain or snow flows across the land, forming rivers and lakes again.

The water cycle affects ecosystems in many ways:

• Plants need water to grow, so the water cycle helps them get the water they need.
• Animals need water to drink, so the water cycle provides them with fresh water.
• The water cycle helps keep the air clean by washing away pollutants.
• The water cycle creates habitats for animals, like rivers and lakes, where they can live and thrive.

Without the water cycle, our planet would be a very dry and empty place. So, it's really important for keeping our ecosystems healthy and full of life.
