The first step that is necessary to take before entering fully to determine the meaning of the term atmosphere is to make its etymological origin clear. In this sense, we can state that it emanates from Greek, since it is made up of two words from that language:
"Atmos", which can be translated as "steam."
"Sphaira", which is synonymous with "sphere".
The term of our language is used to name the gaseous mantle that is surrounding a planet or another type of astronomical object.
The most common use of the concept is linked to earth's atmosphere, that is, to the gas layer which is around the Land. For example: "The spacecraft remained out of the atmosphere for two months", "The company was fined because its factory emitted polluting gases that damaged the atmosphere", "This telescope will allow you to see beyond the atmosphere".
The gases that form an atmosphere are attracted to the celestial body because of the law of gravity. These gases remain around the body in question due to the attraction generated by the gravity.
In the case of earth's atmosphere, measures more than a hundred kilometers. Most of your massIn any case, it is found within the closest ten kilometers to the surface of the planet. Among the gases that make up the atmosphere are the oxygen, the nitrogen, the methane, the helium and the carbon dioxide.
The presence of the atmosphere is essential for life to exist on our planet, as it regulates the temperature, absorbs a percentage of ultraviolet rays and protects the Earth from falling meteorites.
It should not be overlooked that there is also what is known as the atmosphere of Mars. As its name indicates, it is the planet Mars, the fourth in the Solar System, and is identified by the following characteristics:
• It is made up of argon, carbon dioxide, nitrogen, water, methane, and oxygen.
• Its atmospheric pressure varies between 30 Pa to 1155 Pa.
• It is light.
• Regarding its thickness, it can be indicated that it is approximately 11 kilometers.
• The atmosphere of Mars is also composed of four different layers: the exosphere, the upper or thermosphere, the middle and the lower. The latter is identified as being warm.
• For many reasons it differs from that of Earth. However, the main issue in this regard is that Mars contains much less gas than Earth's.
In a symbolic sense, the idea of atmosphere (the Royal Spanish Academy also accepts the term atmosphere, without accent) allows you to name the influence that exerts a person or a thing, or the mental tendency towards something: "In Argentine soccer there is always a violent atmosphere", "I don't like the atmosphere of this party".
In relation to this meaning, we have to state that, in various countries of the world, it is used to shape certain expressions or phrases. Thus, for example, in Cuba it is said "to form an atmosphere", to show that an absolutely unpleasant situation has been caused for one or more reasons.
