write around 2 paragraph on atmosphere
Answers
Answer:
The atmosphere is the layer of gases around the Earth. It is held in place by Earth's gravity.There are total 5 layers of atmosphere, named stratosphere, troposphere, mesosphere, thermosphere, and exosphere. It is made up mainly of nitrogen (78.1%). 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. It makes our days cooler and our nights warmer.
Solid particulates, including ash, dust, volcanic ash, etc. are small parts of atmosphere. They are important in making clouds and fog.
The atmosphere does not end at a specific place. The higher above the Earth, the thinner the atmosphere. There is no clear border between the atmosphere and outer space, though the Kármán line is sometimes treated as a border. Even higher, for some purposes the edge of the magnetosphere is treated as a border. 75% of the atmosphere is within 11 kilometres (6.8 miles) of the Earth's surface.
Answer:
Atmosphere is a protective layer of gases that shelters all life on Earth, keeping temperatures within a relatively small range and blocking out harmful rays of sunlight.”
An atmosphere is a blanket of gases that surrounds Earth. It is held near the surface of the planet by Earth’s gravitational attraction. Argon, oxygen and nitrogen from the three main constitutions of the atmosphere.
The atmosphere:
contains the air that we breathe
helps retain the sun’s heat and prevents it from escaping back into space
protects life from harmful radiation from the sun
plays a major role in Earth’s water cycle
helps keep the climate on Earth moderate
There is no boundary between the atmosphere and outer space. The atmosphere gets less dense and denser until it “blends” into outer space.
Hope this helps ❤️
