What happens in stratosphere?

Stratosphere. … The stratosphere extends from the top of the troposphere to about 50 km (31 miles) above the ground. The infamous ozone layer is found within the stratosphere. Ozone molecules in this layer absorb high-energy ultraviolet (UV) light from the Sun, converting the UV energy into heat.

Why is the ozone layer so important?

The ozone layer protects the Earth against most UVB coming from the sun. It is always important to protect oneself against UVB, even in the absence of ozone depletion, by wearing hats, sunglasses, and sunscreen. However, these precautions will become more important as ozone depletion worsens.

What is the importance of this layer within the thermosphere?

What is the importance of this layer within the thermosphere? The ionosphere makes long distance radio communication possible by reflecting radio waves back towards Earth.

What is important about the stratospheric ozone layer?

Stratospheric ozone is a naturally-occurring gas that filters the sun’s ultraviolet (UV) radiation. This is typically regarded as ‘good’ ozone since it reduces the harmful effects of ultraviolet (UV-B) radiation. A diminished ozone layer allows more radiation to reach the Earth’s surface.

What is the significance of understanding the characteristics of the earth?

Understanding the characteristics of Earth is important, because it can provide us important knowledge about why it is so unique than any other planet in the solar system. We must understand this aspect of our planet, because first of all this is our home, we should care and preserve it no matter what.

What are five important details about the stratosphere?

Interesting Stratosphere Facts:

The stratosphere accounts for approximately 24% of the earth’s total atmosphere. The stratosphere contains approximately 19% of the earth’s total atmospheric gases. 90% of the ozone layer is found in the stratosphere’s upper crust.

Do we live in the stratosphere?

Humans live in the lowest layer called the troposphere. It is also the layer where all weather conditions occur. The layers above it are called the stratosphere, the mesosphere, and the thermosphere.

What would happen if the Earth had 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.

What does the lithosphere provide us?

Answer: lithosphere provides you soil and land on which you are walking or sitting right now, they also help in growing plants and help in building of apartments or house etc. these lithospheric plates are also called the tectonic plates .

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 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 is the altitude of stratosphere?

50 kilometers

The stratosphere starts just above the troposphere and extends to 50 kilometers (31 miles) high.

What makes up the air we inhale?

Air is mostly gas

The air in Earth’s atmosphere is made up of approximately 78 percent nitrogen and 21 percent oxygen. Air also has small amounts of lots of other gases, too, such as carbon dioxide, neon, and hydrogen.

What is the importance of ionosphere Why does temperature rise in the ionosphere?

the ionosphere is important because it reflects and modifies radio waves used for communication and navigation. So temperature increases with height in the ionosphere region to the extent that by 150-200km, the Earth’s atmosphere is extremely hot compared to surface temperatures.

What is stratosphere for Class 7th?
