BR2-17 "Weather"

I read this book titled “Weather” This book is divided into 17 contents. There are many kinds of weather. Do you say all kinds of weather? I interested in weather when I read this book. So I recommend it you.

First, I will tell you about kind of weather. The weather is caused by three main things. There are heat, water and air. Water is always moving between the sea, the air and the land. This is called the water cycle. I will tell about the water cycle.
1. The sun warms the water in the sea and turns it into an invisible gas.
2. The gas rises and turns into tiny droplets of water, making clouds.
3. The tiny droplets bump into each other and join together to make bigger drops.
4. When the drops of water become heavy enough they fall as rain.
5. Rivers carry the rainwater back to the sea. The water cycle begins again.

Second, I will tell about electric skies. Thunderstorms happen when a cumulonimbus cloud forms in the sky. Strong winds inside the cloud swirl rain, snow and hailstones up and down. This makes electricity build up. It escapes down to the ground as flashes of lightning. Lightning sometimes hits trees and buildings on its way from the cloud to the ground.

I thought the weather is interesting because they always change everyday. Today is sunny, but tomorrow may be rainy. And there are many methods to forecast the weather. So I try to forecast the weather.
