Atmosphere
Is a space where several layers contain a mixture of gases, called the atmosphere because it surrounds the earth, and these layers surrounding the land with the attraction of gravity, the proportion of gases occupied by nitrogen gas, two thirds of the total gases exist, and then occupy the remaining gases the remaining one third distributed Between oxygen, hydrogen, water vapor, carbon dioxide, argon, helium, neon, xenon. The most important function of the atmosphere is to protect the Earth from absorption of ultraviolet radiation and the preservation of the Earth within certain temperatures that are the temperature of the planet that enables it to survive. And the second most important functions that carries large amounts of water transported around the earth, some of these amounts fall rain problem on the surface of the earth, especially in large water bodies such as the oceans and seas. The amount of precipitation controls the temperature of the atmosphere and the temperature of the earth

The atmosphere around the whole earth is composed of air, the name that collects space from the Earth's surface into outer space. The atmosphere is part of the air but has certain characteristics. The air that touches the surface of the earth and rises up to the beginning of the atmosphere has certain properties, Which are covered by temperature changes

The atmosphere As we mentioned earlier is a space containing several layers, scientists have divided these layers according to several properties, the most important gases contained in each layer, the differences in temperature between layers, density

Atmospheric sections

The atmosphere contains six layers, resulting in insomnia to the surface of the earth until the farthest

Troposphere
This layer contains the largest amount of water vapor and each of the gases of oxygen and carbon dioxide, is responsible for the majority of changes in the weather, which we deal with and we touch and notice.
Stratosphere
Is the next layer of the troposphere, which distinguishes it from the rest of the layers being almost free from the changes in the air inside and the absence of storms, the most important in this layer is the part that extends in the form of a belt and this layer is responsible for protecting the Earth from ultraviolet radiation.
Mizufer
Its characteristics are that they start at high temperatures and gradually decrease as they move away from the Earth's surface. Its primary and most essential task is to protect the Earth from external objects destined for it

These are the three most important layers in the atmosphere that we can feel on the ground, and then the layers of the casing fall from the lowest to the higher of the layers we mentioned
