Why is an atmosphere important?
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 the most important part of the atmosphere?
Option a: Troposphere is regarded as the most important layer of atmosphere. It is the lowermost layer of the atmosphere and contains 75% of all air in the atmosphere. Most clouds occur in this layer because 99% of the water vapour in the atmosphere is found here.
What is the importance of atmosphere Class 6?
The atmosphere protects the Earth from the solar radiation. It filters the harmful ultraviolet rays of the Sun. The atmosphere traps the required heat of the Sun and allows the rest to escape into space, thus maintaining a moderate temperature on the Earth. This ensures the existence of various life forms.
What is atmosphere short note?
An atmosphere is the layers of gases surrounding a planet or other celestial body. Earth’s atmosphere is composed of about 78% nitrogen, 21% oxygen, and one percent other gases.
Which is the most important layer of the atmosphere Why do you think it is important?
Importance of troposphere to life on earth The study of the troposphere is very important because we breathe the air in this layer of air. The troposphere contains about 85% of the atmosphere’s total mass.
Why is atmosphere important to man?
The atmosphere protects us from UV and other short wavelength light that would otherwise do a lot of damage to the DNA of living organisms. The atmosphere is also important because it contains oxygen, which we and other living organisms breathe.
What is the importance of atmosphere in geography?
The importance of the atmosphere is as follows: The atmosphere protects the Earth from the solar radiation. It filters the harmful ultraviolet rays of the Sun. The atmosphere traps the required heat of the Sun and allows the rest to escape into space, thus maintaining a moderate temperature on the Earth.
Can you tell me why the atmosphere is important?
Protection against the sun’s rays. The ozone layer protects life on earth from the harmful effects that excess solar rays can have.
Why is the atmosphere important to all living things?
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.
Why does the Earth need atmosphere?
The atmosphere also helps to sustain life of Earth. It provides oxygen for humans and animals to breathe, and carbon dioxide for plants. Through the hydrological (precipitation) cycle, plants and animals receive the water they need to survive.
Why are the layers of the atmosphere important to US?
The atmosphere is a huge protective layer around the Earth. Its different layers are like a filter , keeping the sun’s harmful radiations from reaching the surface of the Earth. It allows only a part of the sun’s heat to reach us, thus preventing the Earth from getting too hot.
