THE ATMOSPHERE AND WEATHER. Air surrounds the earth and extends out for about 1,000 miles, gradually fading into space at that point. It is called the atmosphere. The air gets thinner the farther it is from the earth. It has no color, no smell and no taste but it is really several gases mixed together. You cannot see it, yet it is as real as land and water. The atmosphere is made up of 78 per cent nitrogen and 21 per cent oxygen. The remaining 1% consists of small amounts of argon and other gases. The atmosphere is divided into several layers with the Troposphere being the lower level. It extends up to about eight miles or 42,000 feet. It is the region of most weather. The Stratosphere extends to about 25 miles. It is a stable area with minimum temperatures and little change.
