It's amazing how many questions a child can ask about the weather! Why is the wind blowing? Where do clouds come from? What is fog? Why is there dew on the grass in the mornings? The author of this book, Pyotr Voltsit, will introduce kids to natural phenomena – thunderstorms, wind, rain, hail, and will explain why the weather on Earth is so different and changeable. For younger school age.
