Atmosphere is a layer of air that surrounds the earth, recognize its division and benefits

According to the Big Indonesian Dictionary, the atmosphere is a layer of air that surrounds the earth to a height of 300 km (mainly consisting of a mixture of various gases, namely nitrogen, oxygen, argon, and small amounts of other gases).

Atmosphere is a term that comes from the Greek, namely atmos which means steam and sphere which means layer. The thickness of the atmosphere is about 1000 km around the earth and is divided into several layers.

The atmosphere is the gas that surrounds the earth which consists of several main gases, such as nitrogen as much as 78%, oxygen as much as 21%, argon 0.9%, carbon dioxide 0.09%, and minor gases such as neon, helium, methane, krypton, hydrogen, ozone, etc. which are relatively very small in number, usually expressed in PPM (parts per million) or PPB (parts per billion).

The atmosphere is a layer of air that serves to regulate the process of receiving heat from the sun. The heat emitted by the sun is absorbed and reflected by the atmosphere. About 34% of the sun’s heat is reflected back into space by the atmosphere, clouds, and also the earth’s surface. Then about 19% is absorbed by the atmosphere and clouds, then the remaining 47% reaches the earth’s surface.

The atmosphere is a layer of air consisting of several layers, namely the troposphere, stratosphere, mesosphere, ionosphere, thermosphere, and exosphere.
