Atmosphere is the thin layer of air that surrounds the earth. It is made up of various gases such as oxygen, nitrogen, carbon dioxides, dust particles and water vapour. The gravitational force of the earth holds the atmosphere around it. It protects us from harmful rays and scorching heat of the sun.

What would happen without an atmosphere?

The lack of atmosphere would chill the Earth’s surface. We’re not talking absolute zero cold, but the temperature would drop below freezing. Water vapor from the oceans would act as a greenhouse gas, raising the temperature. … However, some bacteria could survive, so losing the atmosphere wouldn’t kill all life on Earth.

Why is the study of atmosphere important to us?

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.

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.

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 the conclusion of atmosphere?

The air we breathe

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 four uses of atmosphere?

What is the importance of each layer of the atmosphere?

They are the following from top to bottom (near the surface): Exosphere, Thermosphere, Mesosphere, Stratosphere and Troposphere. These five different layers provide protection and also make life possible because of the constituent gases which state the significance and importance of atmosphere.

What is atmosphere Why is it said that without atmosphere life is not possible?

Our atmosphere allows just enough of the sun’s energy back into space so that we do not get to hot like Venus or too cold like Mars. If Earth had no atmosphere, apart from having no air to breathe, the surface of the Earth would be 0 degrees Fahrenheit.

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.

Is the atmosphere hot or cold?

Some parts of the atmosphere are hot or cold, depending on height. Starting from the surface and climbing straight up, the air gets colder in the troposphere, but then it becomes hotter, higher in the stratosphere. These changes of temperature are divided into layers. These are like layers of an onion.

How is atmosphere important for us Class 5?

The atmosphere protects us from various harmful gases and air would not exist without the atmosphere. It also keeps the earth warm at nights and provides gases like carbon dioxide and nitrogen to plants.
