The atmosphere protects life on earth by shielding it from incoming ultraviolet (UV) radiation , keeping the planet warm through insulation, and preventing extremes between day and night temperatures. The sun heats layers of the atmosphere causing it to convect driving air movement and weather patterns around the world.
What is atmosphere Why is atmosphere important to us?
Complete Answer:
The atmosphere contains the air that we breathe ; protects us from the harmful radiation of the Sun; helps to keep the planet’s heat on the surface, and plays a very important role in the water cycle.
Which of the following is a reason why the atmosphere is important?
The Earth’s atmosphere protects and sustains the planet’s inhabitants by providing warmth and absorbing harmful solar rays . In addition to containing the oxygen and carbon dioxide, which living things need to survive, the atmosphere traps the sun’s energy and wards off many of the dangers of space.

Atmosphere is essential for life on Earth as it supplies oxygen, water, CO 2 and some nutrients (N) to living organisms, and protects living organisms from temperature extremes and excessive UV radiation.
What are the four functions of the atmosphere?
The atmosphere of Earth protects life on Earth by creating pressure allowing for liquid water to exist on the Earth’s surface, absorbing ultraviolet solar radiation, warming the surface through heat retention (greenhouse effect), and reducing temperature extremes between day and night (the diurnal temperature variation ...
What are 3 facts about the atmosphere?
The atmosphere is made up of 78% nitrogen, 21% oxygen, and smaller amounts of argon, carbon dioxide, helium, and neon . Contaminants in the atmosphere can include smoke, toxic gasses, dust, ash from volcanoes, and salt.

In addition to containing the oxygen and carbon dioxide, which living things need to survive, the atmosphere traps the sun’s energy and wards off many of the dangers of space.
What are the disadvantages of atmosphere?
- 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.

What is atmosphere in simple words?
Atmosphere is defined as the area of air and gas enveloping objects in space, like stars and planets, or the air around any location . An example of atmosphere is the ozone and other layers which make up the Earth’s sky as we see it. An example of atmosphere is the air and gases contained inside a greenhouse.
What are the functions of the layers of the atmosphere?
Different layers of the atmosphere are: Troposphere – It is the layer just above the earth’s surface whose distance is between 0 – 10km. It contains most of the air and oxygen which is essential for all living organisms. This air is used for respiration and other functions for the survival of human beings .
