Why Do We Need The Atmosphere?
Not only does it contain the oxygen we need to live but it also protects us from harmful ultraviolet solar radiation. It creates the pressure without which liquid water couldn’t exist on our planet’s surface. And it warms our planet and keeps temperatures habitable for our living Earth.Oct 2 2019
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.

Why is it important to study the atmosphere?
One of the most important benefits the atmosphere provides is maintaining the Earth’s temperature. … The molecules also trap reflected energy from the surface preventing the night side of the planet from becoming too cold. Radiation. The atmosphere serves as a protective shield against radiation and cosmic rays.
Which is a very important part of the atmosphere?
Nitrogen and oxygen together make up 99% of the planet’s atmosphere. The rest of the gases are minor components but sometimes are very important (Figure below). Nitrogen and oxygen make up 99% of the atmosphere carbon dioxide is a very important minor component. Humidity is the amount of water vapor in the air.
What is the importance of atmosphere Class 6?
Atmosphere. The layer of gases surrounding the earth is called the atmosphere. It is a thin blanket of air that gives us oxygen to breathe and protects us from the harmful rays of the sun. It stretches up to 1600 km and is divided into five layers based on temperature composition (mix of gases) and other properties.
What is the significance of the atmosphere on Earth as compared to other planets?
The significance of earth atmosphere is more as comparet to other planets as it protects us from harmful ultra violet rays of sun and it covers the earth like a blanket. It also helps in maintaining the earth’s temperature.
What is the conclusion of atmosphere?
Life on Earth would not be possible without our air. Our air (the atmosphere) provides us with oxygen to breathe and carbon dioxide for plants to live. But the atmosphere does a lot more than provide air for living organisms. The atmosphere also helps to regulate Earth’s temperature.
What is the atmosphere paragraph?
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. … The atmosphere protects life on Earth by absorbing (taking) ultraviolet rays from the sun.
What is the atmosphere introduction?
What is atmosphere in your own words?
1 : the whole mass of air that surrounds the earth. 2 : the gas surrounding a heavenly body (as a planet) The atmosphere of Mars is made up mostly of carbon dioxide. 3 : the air in a particular place. 4 : a surrounding influence or set of conditions an atmosphere of excitement.
What is atmosphere Class 9?
Why is the atmosphere so important to us write at least five advantages?
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.
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.
Which is the most important layer of the atmosphere Why do you think it is important class 7?
Ans: Troposphere is considered as the most important layer of the atmosphere because:- A) All weather phenomena such as cloud rainfall storms etc. occur in this layer. B) The temperature of the air decreases with the increase in height at rate of 1°c for every 165 m which is known as normal lapse rate.
Can we survive without the atmosphere?
If Earth had no atmosphere apart from having no air to breathe the surface of the Earth would be 0 degrees Fahrenheit. … The atmosphere contains the warmth we all need to survive the oxygen we all breathe and carries the rain we all need. Without our atmosphere life as we know it would cease to exist.
How does the atmosphere help to regulate the earth’s temperature?
The atmosphere also helps to regulate Earth’s temperature. … Every day sunlight (the sun’s radiation) travels through the atmosphere and warms the planet. The atmosphere helps to trap this warmth on Earth – if you remember from the introduction this process is called the greenhouse effect.
What is structure of atmosphere?
The atmosphere is comprised of layers based on temperature. These layers are the troposphere stratosphere mesosphere and thermosphere. A further region at about 500 km above the Earth’s surface is called the exosphere.
What is an example of a connection between atmosphere and biosphere?
the atmosphere which contains all of the planet’s air. These spheres are closely connected. For example many birds (biosphere) fly through the air (atmosphere) while water (hydrosphere) often flows through the soil (lithosphere).
What is a fact about atmosphere?
The atmosphere is a layer of gases most commonly referred to as air that is retained by the gravity of earth. The atmosphere surrounds the planet protecting it by absorbing the ultraviolet radiation from the sun and regulating the temperature extremes that would otherwise occur between day and night.

What is the main function 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 would happen if there was no atmosphere?
If there were no atmosphere around the earth the temperature would get affected. In the absence of atmosphere there would be no life no rains no winds no fires and also no ozone layer that would be used as a protection layer against harmful radiations.
Why is it called atmosphere?
An atmosphere (from Ancient Greek ἀτμός (atmós) ‘vapour steam’ and σφαῖρα (sphaîra) ‘sphere’) is a layer of gas or layers of gases that envelope a planet and is held in place by the gravity of the planetary body.
