Which layer of the atmosphere warms because ozone absorbs UV radiation from the sun?
Which layer of the atmosphere warms because ozone absorbs UV radiation from the sun?
The stratosphere
How ozone layer increases the temperature of stratosphere?
Ozone generates heat in the stratosphere, both by absorbing the sun’s ultraviolet radiation and by absorbing upwelling infrared radiation from the lower atmosphere (troposphere). Consequently, decreased ozone in the stratosphere results in lower temperatures.
What is the hottest outermost layer of the atmosphere?
Exosphere
What is Corona of Sun?
Definition: Corona is a luminous envelope of plasma that surrounds the Sun and other celestial bodies. It is extended to millions of kilometres into space and is commonly seen during a total solar eclipse. Description: The corona of the Sun is much hotter than its visible surface.
Why exosphere is so hot?
The particles in the exosphere are moving very quickly, so the temperature there is quite hot. Since the “air” is so thin in the exosphere – it is almost a vacuum – there are very, very few particles. We feel warmth when particles hit our skin and transfer heat energy to us.
What is the hottest and coldest layer 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.
Why is it so hot in the thermosphere?
The thermo- in thermosphere means “heat.” Even though the air in the thermosphere is thin, it is very hot, up to 1,800°C. This is because sunlight strikes the thermosphere first. Nitrogen and oxygen molecules convert this energy into heat.
Does Air always move in troposphere?
Air flows horizontally at top of the troposphere; horizontal flow is called advection. The air cools until it descends. Where it reaches the ground, it creates a high pressure zone. Air flowing from areas of high pressure to low pressure creates winds.
What level of atmosphere do planes fly in?
stratosphere
Why do planes fly at 35000 feet?
The thinner the air is, the less resistance/drag there is on the plane, so less fuel is needed for the plane to hit the same speed (the weight of the plane also helps to conserve fuel, which is why airlines have figured out all sorts of crazy ways to decrease a plane’s weight), and therefore there’s more energy …
