It acts like a greenhouse and keeps the average temperature of the earth around 35°C and also protects the earth from the harmful radiation of the sun. The atmosphere is a storehouse for water vapour and serves as the medium of faster air transport.
What does the atmosphere do for us give three reasons?
The atmosphere blocks out harmful rays from the sun. The ozone layer, which lies in the stratosphere 11 to 50 kilometers from the Earth’s surface, blocks out many harmful forms of radiation. Without the ozone layer, ultraviolet rays would destroy most life on Earth. Gases in the atmosphere also hold in heat.

The atmosphere is a protective layer that safeguards the earth from the harsh conditions of the solar system. … During the day, it prevents a sudden increase in the temperature of the earth and prevents the heat to escape to the outer space during the night. It keeps the average temperature of the earth steady.How does the atmosphere make life possible?
It contains roughly 78% nitrogen and 21% oxygen 0.97% argon and carbon dioxide 0.04% trace amounts of other gases, and water vapor. This mixture of gases is commonly known as air. The atmosphere protects life on Earth by absorbing ultraviolet solar radiation and reducing temperature extremes between day and night.
Why is atmosphere important for us Class 6?
The atmosphere is essential for life for the following reasons: (a) Oxygen, which is essential for the survival of all living organisms, is present in the atmosphere. (b) Essential gases that support life on the earth are present in the atmosphere. (c) Water cycle would not have been possible without the atmosphere.
What is the reason why the atmosphere is essential to life Brainly?
Oxygen present in the atmosphere is required for the survival of every living organism. Atmosphere works as an insulator and keeps the temperature of the earth constant during day and night by preventing terrestrial radiation. It protects from UV rays.
What is atmosphere easy 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 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.
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 are the 3 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 …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.
Which layer of the atmosphere is most important for us and why?
troposphere
Importance of troposphere to life on earthThe 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.
What is the function of the atmosphere in the environment?
The atmosphere protects Earth from harmful solar radiations and regulates heating provided by the Sun. The first function is made possible by ozone existing in the stratosphere, the second function is achieved by a mix of gases existing in the whole atmosphere called “greenhouse gases”.
What do you want to know about the atmosphere?
As the altitude of air increases there is a decrease in atmosphere gases in the air—all the water and weather in the atmosphere are contained to the lower 30 km of atmosphere, 99% of the atmospheric gases are below 50 km in altitude, but trace atmospheric gases can trail out thousands of kilometers.
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.
What are the main two roles of atmosphere?
Atmosphere is essential for life on Earth as it supplies oxygen, water, CO2 and some nutrients (N) to living organisms, and protects living organisms from temperature extremes and excessive UV radiation.
How does the atmosphere allow us to hear?
A layer of ozone gas in the stratosphere absorbs high-energy ultraviolet (UV) radiation from the sun. … Gas molecules in the atmosphere transmit sound waves to our ears and allow us to hear. Without the atmosphere, Earth would be a virtually silent place.
Why is the atmosphere important to all living things survival?
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.
What atmosphere do living things need to survive?
Carbon dioxide and oxygen are the gases in the atmosphere that are needed for life. Plants need carbon dioxide for photosynthesis. They use sunlight to change carbon dioxide and water into food. The process releases oxygen.
