What is the role of atmosphere in climate control class 9?
Role of Atmosphere in Climate Control As air in the atmosphere is bad conductor of heat, it helps to maintain the erth’s temperature by preventing the sudden increase in temperature during day and also during the night, it slows down the escape of heat into the outer space.
How does atmosphere help in climate control 2?
The atmosphere prevents the sudden increase in temperature during the daylight hours. And during the night, it slows down the escape of heat into outer space The atmosphere keeps the average temperature of the Earth fairly steady during the day and even during the course of the whole year.
How does the atmosphere control climate and temperature?
The atmosphere captures the heat reflected by the Earth’s surface. The property of the atmosphere to capture the heat is due to the presence of gases called greenhouse gases. The atmosphere helps to maintain the temperature by capturing the Sun’s heat.
How does the atmosphere affect climate?
The atmosphere is warming. A warming atmosphere affects more than just air temperatures: while heat waves and droughts are becoming more common and intense, rainstorms are also becoming more powerful, sometimes provoking dangerous floods.
What is the impact of the atmosphere?
Very little of the radiation emitted by Earth’s surface passes directly through the atmosphere. Most of it is absorbed by clouds, carbon dioxide, and water vapour and is then reemitted in all directions. The atmosphere thus acts as a radiative blanket over Earth’s surface, hindering the loss of heat to space.
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 would happen if there was no atmosphere?
The temperature of the Earth would rapidly start to rise once our atmosphere had disappeared. Without our atmosphere we have little protection from the Sun’s heat. It would penetrate to the Earth’s surface and cause the water to start boiling off into steam that would float off into space.
What is the role of the atmosphere?
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 are the disadvantages of atmosphere?
Drawbacks
- 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 most important function of the atmosphere?
The atmosphere acts as a gigantic filter, keeping out most ultraviolet radiation while letting in the sun’s warming rays. Ultraviolet radiation is harmful to living things, and is what causes sunburns. Solar heat, on the other hand, is necessary for all life on Earth. Earth’s atmosphere has a layered structure.
What is the most important part of the atmosphere?
Troposphere
What are 3 facts about the atmosphere?
Fun Facts About the Atmosphere for Kids
- There are five layers within the atmosphere.
- The troposphere lies closest to the Earth and is about 11 miles thick.
- The stratosphere lies above the troposphere and goes up about 30 miles high.
- The mesosphere is the next layer, reaching 50 miles from the Earth.
How important are the layers of the atmosphere?
In some layers, temperature increases with altitude and in others it decreases. The temperature gradient in each layer is determined by the heat source of the layer. Most of the important processes of the atmosphere take place in the lowest two layers: the troposphere and the stratosphere.
Why the mesosphere is the coldest layer in the atmosphere?
The top of the mesosphere is the coldest part of the atmosphere. In the mesosphere, the thin air and small amounts of ozone prevent the air from warming much. Carbon dioxide in the mesosphere also helps make this layer cold. CO2 molecules absorb heat energy when they bounce off of other molecules.
Why can’t planes fly in the mesosphere?
The mesosphere is the layer of atmosphere that lies above the stratosphere. Mesosphere is the coldest part of the atmosphere. Aeroplanes and hot air balloons can’t fly high enough to reach the stratosphere and satellites fly above the stratosphere. …
What are the hottest and coldest layers of the atmosphere?
Coldest layer of Earth’s atmosphere is the MESOSPHERE. The temperature there is -90 degree celsius. It can even go lower. Hottest layer of Earth’s atmosphere is the thermosphere.
