Weather By The Moon the atmosphere. The scale of size of the atmosphere is incredible. The imagination can only boggle at something weighing so much that can, and frequently does when the Moon dictates, move so fast. There is no sea tide remotely like it. On a hot afternoon, the atmosphere picks up water from the Gulf of Mexico at the rate of 5.5 billion tons an hour, hoists it up and carries it northeast by the millions of tons, to release it later as rain over New York and southern New England. A single, small, fluffy cloud may hold from 100 to 1,000 tons of moisture. A summer thunderstorm may unleash as much energy in its short life as a dozen Hiroshima-style bombs, and 45,000 thunderstorms are brewed around the Earth every day. Yet one hurricane releases almost as much energy in one second. The very size of the atmosphere offers protection or shielding, between the Earth’s surface and space. Without the shielding of the atmosphere, life could not continue on Earth; and without the atmosphere life could not have developed on Earth, at least in the form in which we know it. It is known, for example, that the Sun emits high - energy radiations - ultraviolet and X rays - and that even more energetic radiations - cosmic rays, pervade space; and these radiations would kill living things. We know that they enter the atmosphere in lethal amounts but are stopped long before reaching the surface. The absorption by the atmosphere of these powerful forms of radiation accounts for many of the properties, particularly electrical, of the higher atmosphere. 78

The atmosphere shelters us from the fierce heat and cold of space, filters out damaging rays of sunlight and burns up several million billion meteors each day to harmless cinders before they reach the earth’s surface. It pulls up water from the ocean surface and recycles it to nourish life all across the planet. What constitutes the atmosphere? The mixture of gases is generally called air. Its main constituents are nitrogen and oxygen, in a ratio of about four to one. By percentage of volume of water, one part in 1000 is in the air. .
