What is atmosphere in simple words?
The atmosphere is the layer of gases around the Earth. It is held in place by Earth’s gravity. It also has plentiful oxygen (20.9%) and small amounts of argon (0.9%), carbon dioxide (~ 0.035%), water vapor, and other gases. The atmosphere protects life on Earth by absorbing (taking) ultraviolet rays from the sun.
What is the same meaning of atmosphere?
An atmosphere is a surrounding environment or influence. If you and your coworkers talk behind each other’s backs, you will create a nasty atmosphere at work. Atmosphere was coined by 17th-century scientists combining the Greek words for vapor, atmos, and sphere, sphaira. Some plants grow best in a damp atmosphere.
What do atmospheric mean?

What is the main work of atmosphere?
The atmosphere is an important part of what makes Earth livable. It blocks some of the Sun’s dangerous rays from reaching Earth. It traps heat, making Earth a comfortable temperature. And the oxygen within our atmosphere is essential for life.
What are the two characteristics of atmosphere?
In addition to containing nitrogen and oxygen, the atmosphere contains small particles, such as dust, volcanic ash, sea salt, dirt, and smoke. The next time you turn off the lights at night, shine a flashlight, and you will see some of these tiny particles floating in the air. Water is also found in the atmosphere.
How thick is the mesosphere in the earth?
Mechanical Layers
| Layer | Depth |
|---|---|
| Lithosphere | 0-100 km |
| Asthenosphere | 100-350 km Soft plastic *note: The mantle is not liquid! |
| Mesosphere | 350-2900km stiff plastic |
| Outer Core | 5100-6370 km solid |
What does the mesosphere protect us from?
The mesosphere is very important for earth’s protection. The mesosphere burns up most meteors and asteroids before they are able to reach the earth’s surface. The mesosphere is the coldest atmospheric layer surrounding the earth. It becomes cold enough to freeze water vapour in its atmosphere into ice clouds.
What gases are in the mesosphere?
nitrogen (78,08%) oxygen (20,95%) argon (0,93%) carbon dioxide and other trace gases (0,04%)
Does the mesosphere have oxygen?
The percentage of oxygen, nitrogen, and carbon dioxide in the air in the mesosphere is essentially the same as that in the levels of the Earth’s atmosphere immediately above the Earth’s surface. The winds in the stratosphere and mesosphere are usually estimated from temperature data collected by…
What would happen if there was no mesosphere?
The mesosphere is the least known layer of the atmosphere. The mesosphere lies above the highest altitude an airplane can go. If you were in the mesosphere without a space suit, your blood would boil! This is because the pressure is so low that liquids would boil at normal body temperature.
What are the importance of the atmosphere?
The atmosphere protects living things from the Sun’s most harmful rays. Gases reflect or absorb the strongest rays of sunlight (figure below). The atmosphere shields Earth from the most harmful solar rays.
