Gases in the air

(Level - Easy)

We hardly ever notice the mixture of gases that surround us. We only realize it if there is a strong wind, or when fog or smog cuts off our view into the distance. Yet we depend on the air in many ways. It provides the oxygen that we breathe. Plants, on which all animals depend for food, could not live without the carbon dioxide in the air. And it is a barrier, hundreds of miles deep, protecting us from the burning ultra-violet rays of the sun. Fast-moving pieces of stone called meteoroids are burnt up when they enter the atmosphere from space, before they can reach the ground. And cosmic rays, which are made up of fragments of atoms traveling from distant parts of space, are slowed down before they can do damage.
