Answer:
The atmosphere is a mixture of gases that surrounds the planet. On Earth, the atmosphere helps make life possible. Besides providing us with something to breathe, it shields us from most of the harmful ultraviolet (UV) radiation coming from the Sun, warms the surface of our planet by about 33° C (59° F) via the greenhouse effect, and largely prevents extreme differences between daytime and nighttime temperatures. The other planets in our solar system also have an atmosphere, but none of them have the same ratio of gases and layered structure as Earth's atmosphere.

The atmosphere is made up of a variety of gases. The amount of these gases also varies.
Explanation:
- The Earth's atmosphere is made up of layers of gases that surround it. Gravity is the glue that holds everything together.
- It contains a variety of gases, the most of which are in trace levels. Nitrogen is the most abundant gas in the atmosphere. It accounts for 78% of the overall atmosphere.
- Oxygen makes up 21% of the atmosphere, whereas argon makes up 0.9 percent. Carbon dioxide, nitrous oxides, methane, and ozone all make up around a tenth of a percent of the atmosphere. Water vapour concentrations range from 0 to 4 percent depending on location and time.
