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.
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.
Why is the atmosphere so important?
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 is the importance of atmosphere Class 7?
The
atmosphere blocks harmful ultra-violet radiations to reach Earth
. The atmosphere contains oxygen, the gas living beings need to breathe to stay alive. The moisture it contains is an essential part of the water cycle. Green plants need the carbon dioxide present in the atmosphere for making food.
What is the importance of the atmosphere essay?
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 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.
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 the 5 types of atmosphere?
Earth’s atmosphere has five major and several secondary layers. From lowest to highest, the major layers are the
troposphere, stratosphere, mesosphere, thermosphere and exosphere
. Troposphere.
What do you mean atmosphere?
An atmosphere is
the layers of gases surrounding a planet or other celestial body
. … These gases are found in layers (troposphere, stratosphere, mesosphere, thermosphere, and exosphere) defined by unique features such as temperature and pressure.
What are the 7 layers of atmosphere?
- The Troposphere. This is the lowest part of the atmosphere – the part we live in. …
- The Stratosphere. This extends upwards from the tropopause to about 50 km. …
- The Mesosphere. The region above the stratosphere is called the mesosphere. …
- The Thermosphere and Ionosphere. …
- The Exosphere. …
- The Magnetosphere.
What is the role of atmosphere Class 9?
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.
What is the important of dust in the atmosphere?
Even though dust is a relatively small constituent of the atmosphere, it is
very important to weather and climate
: Without dust particles, water vapor cannot condense or freeze to form fogs, clouds, and precipitation from clouds. … Besides fire, we raise dust in plowing and in allowing our animals to overgraze.
What are the most important components of the atmosphere?
- Nitrogen — 78 percent.
- Oxygen — 21 percent.
- Argon — 0.93 percent.
- Carbon dioxide — 0.04 percent.
- Trace amounts of neon, helium, methane, krypton and hydrogen, as well as water vapor.
What are the disadvantages of the 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 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 3 ways the atmosphere is important to life on Earth?
- Protection. The atmosphere blocks out harmful rays from the sun. …
- Water. The Earth’s atmosphere contains water. …
- Oxygen and Carbon Dioxide. Life on Earth needs the atmosphere to breath. …
- Other Benefits. The atmosphere contains a large amount of nitrogen.
