They are very difficult to answer, aren't they?      If someone asks you:"What color is the sky?" I think maybe you will answer"Blue". I am afraid you are wrong. The sky has no colors. When we e blue, it is the sunlight that is shining on little bits of dust in the air.      Is the sky full of air? I am sure you have asked this question, too. We know that there is air all around the earth. Planes can't fly without air. They need air to lift their wings. Planes can't fly very high becau as they go higher, the air gets thinner. If we go too high up in the sky, we find there is no air.      Perhaps you can answer some of the questions now. What is the sky? Nothing. Where is it? It is all around the earth. The sky is a part of space. 1. What color is the sky according to the writer? A. Blue. B. White. C. Black. D. Colorless. 2. What is in the sky?A. It's empty. B. It's full of air. C. It has clouds. D.
