Incredible Earth
About 20 percent(%) of the land on earth is deserts. What are desert made of? Some deserts are made of saned, and many deserts are made of stones and rocks. Deserts are usually hot, but not always. Antarctia is a cold desert. It doesn't rain so often there, but there's lots of ice.(p.20)
Today, I read "Incredible Earth". How amazing and many secrets of the earth is written in this book. My best part is above. Because I never heard about cold desert and also a desert that falls snow there.
Earth has many mysterious things.
