What is atmosphere step by step explanation
Answers
⭐An atmosphere is a layer or a set of layers of gases surrounding a planet or other material body, that is held in place by the gravity of that body. An atmosphere is more likely to be retained if the gravity it is subject to is high and the temperature of the atmosphere is low
⭐Earth's atmosphere is composed of about 78 percent nitrogen, 21 percent oxygen, 0.9 percent argon, and 0.1 percent other gases. Trace amounts of carbon dioxide, methane, water vapor, and neon are some of the other gases that make up the remaining 0.1 percent
⭐The atmosphere gives us weather like wind, rain, and snow. Protects us from objects that are coming to earth from outer space. The atmosphere contains a small amount of carbon dioxide which are important to plants. The atmosphere also helps us talk by making us can hear with the air between two people
⭐Earth's Atmospheric Layers
Troposphere. The troposphere starts at the Earth'ssurface and extends 8 to 14.5 kilometers high (5 to 9 miles). ...
Stratosphere. The stratosphere starts just above the troposphere and extends to 50 kilometers (31 miles) high. ...
Mesosphere. ...
Thermosphere. ...
Ionosphere. ...
Exosphere. ...
⭐Drawbacks
The atmosphere holds in some "greenhouse" gases that retain the heat of the Sun. ...
Clouds regularly obscure good astronomical viewing.
The atmosphere refracts light which means the position and clarity of star viewing is less accurate.
Pollution from light and chemicals obscure observations.

Answer:
The atmosphere is a thin layer of gases that surrounds the Earth. It seals the planet and protects us from the vacuum of space. It protects us from electromagnetic radiation given off by the Sun and small objects flying through space such as meteoroids.
