On a hot summer day, you find the pond has almost dried up. Where did the water go? It goes into the air! Each drop of water is made of droplets. When the sun warms them, they go up and become part of the air. However, do you know how rain is formed (形成)?
High in the sky, the air is cooler. As the water in the air cools, it changes back into droplets. They get together to make clouds.
In the clouds, many many droplets get together and grow bigger. When they are heavy enough, they fall from the sky as raindrops, or if it’s very cold-snowflakes! The water we have on the earth is always moving and changing!
We’ve seen how the sun heats the water so it goes up, cools, and becomes a cloud. In the cloud, droplets join together to become raindrops, and fall back to the earth. Some rainwater goes u again soon, while some joins rivers, lakes, or the ocean. This is called the water cycle.
Rain falls almost everywhere on the earth. One of the world’s rainiest places is Mount Waialeale in Hawaii. It rains about 350 days a year there. One of the driest places on the earth is the Atacama Desert in Chile. It has not rained in some parts of this desert in hundreds of years.
