Which is the important layer of the atmosphere and why?

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.

What is the importance of atmosphere Class 9?

Answer: The atmosphere protects the earth from harmful ultraviolet and infrared rays of the sun. It has oxygen and nitrogen, the life sustaining gases. It helps in retaining the necessary warmth on the earth and helps in the circulation of water vapour as the source of rainfall.

What is atmosphere Class 9?

Ans: Atmosphere is the veil of odourless,tasteless and colourless gases,dust particles and water vapour surrounding the earth which forms a protective boundary between the outer space and the biosphere. It is composed of different gases in different volumes.

What is the most important atmospheric layer?

the troposphere As you see, the troposphere is an important layer in Earth’s Atmosphere, as it is the layer that we live in and the layer that gives us weather.

What are the four layers of the atmosphere which one is most important?

The atmosphere is constituted of layers based on temperature. These layers are the troposphere, stratosphere, mesosphere, thermosphere and exosphere. Looking at the above options: Option a: Troposphere is regarded as the most important layer of atmosphere.

How does the atmosphere keep the Earth warm?

Earth’s atmosphere keeps much of the Sun’s energy from escaping into space. This process, called the greenhouse effect, keeps the planet warm enough for life to exist. … Greenhouse gases in the atmosphere also absorb and hold some of the heat energy radiating back from Earth’s surface.

What is atmosphere one word answer?

Atmosphere is defined as the area of air and gas enveloping objects in space, like stars and planets, or the air around any location. An example of atmosphere is the ozone and other layers which make up the Earth’s sky as we see it. An example of atmosphere is the air and gases contained inside a greenhouse.

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.

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.

What is the significance of atmosphere Brainly?

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.

How does the atmosphere play an important role in the water cycle?

The atmosphere is the superhighway in the sky that moves water everywhere over the Earth. Water at the Earth’s surface evaporates into water vapor which rises up into the sky to become part of a cloud which will float off with the winds, eventually releasing water back to Earth as precipitation.

What is the atmosphere called?

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 the atmosphere introduction?

The Earth’s atmosphere is a thin envelope of gases surrounding the solid planet, the hydrosphere, and biosphere. The composition of the atmosphere consists largely of two elements, oxygen and nitrogen. … This results in the greenhouse effect that keeps the planet warm enough to sustain life.

How does life affect Earth?

Life—including microbes, plants, animals and humans—is a major driver of the global carbon cycle and can influence global climate by modifying the chemical makeup of the atmosphere. The geologic record shows that life has significantly altered the atmosphere during Earth’s history.

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 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.
