Why does temperature in the stratosphere increase with altitude?

In stratosphere there is ozone layer.. that is, 3 oxygen atoms combine together to form an Ozone molecule which absorbs Sun's harmful UV radiation.. It gets excited.. travels fast.. hits another ozone molecule.. friction.. and then heat; hence temp rises in stratosphere..
but in mesosphere, ozone molecules are not formed naturally.. as we know, pressure in mesosphere is less than that in stratosphere.. hence former is less dense (that is, molecules of air/unit volume is less) than later.. the warm air of stratosphere rises (as warm air is lighter) and because of less pressure, it uses its own heat to push the outside air molecules in mesosphere.. hence it becomes cooler; hence temp dec in mesosphere
But in upper thermosphere, the solar wind plasma (4th state of matter) interacts with earth's geomagnetic field.. gets energized.. lets charged particles flow into thermosphere.. they split Oxygen molecules into Oxygen atoms which is molecular diffusion. About 60% of UV absorbed by thermosphere heats ionospheric plasma and neutral gases. 20% of it given out as air glow by excited atoms/molecules. 20% stored as chemical energy given out when atoms recombine. This excess energy released to ion-neutral and neutral chemical reactions heats the upper thermosphere. this heat is conducted downward to the other layers. So we think, heat inc with alt in thermosphere

∙ 11y agoThe reason the temperature increases with increasing altitude is because of what temperature is measured by: the speed of molecules. In the stratosphere, there is very little gas, and molecules can move very quickly because they are not bouncing off of each other (and other factors). Therefore, by the strict definition of 'temperature', the stratosphere is hotter.
However, due to the low amount of gas at that level of the atmosphere, if YOU were to be there (with a gas mask) you would feel terribly cold (aside from feeling like you're being sucked apart by the partial vacuum). The reason for this is that though the 'temperature' is high, there are very very few molecules flying around bouncing into you and warming you. Therefore your body would receive very little heat from the surroundings--BUT you would radiate away a bunch of heat, causing you to be very very cold very quickly. That is also why astronauts need to be careful about the 'cold temperature' of space. But that's a different story.

Does the temperature increase or decrease with altitude in the thermoshpere?
The temperature increases like the stratosphere
In the stratosphere does temperature increase or decrease with altitude?
In the stratosphere, the temperature increases with height. This is due to the presence of the ozone layer near the top of the stratosphere. The ozone layer absorbs incoming UV radiation, and thus the temperatures are warmer at the top of the stratosphere than at the bottom.
How does the temperature change with altitude in the stratosphere?
the temperature already rise as you climb up in the stratosphere.
What happens to the temperature as altitude increases in a stratosphere?
Temperature reaches its coldest at the tropopause, which is the boundary between the troposphere below and the stratosphere above. In the stratosphere, the temperature increases with height due to absorption of radiation by ozone.Temperature changes when altitude is in the stratosphere because of one things. It already rises when you climb up in the stratosphere.
What is a strong wind in the lower stratosphere?
Jet Stream The main jet streams are located near the tropopause, the transition between the troposphere (where temperature decreases with altitude) and the stratosphere(where temperature increases with altitude)
Does the temperature increase or decrease with altitude in the thermoshpere?
The temperature increases like the stratosphere
Which atmosphere layers does the temperature as a altitude increase?
stratosphere and thermosephere -Nikki Gallagher
WHAT Is the difference between stratosphere and mesosphere?
The stratosphere's temperature increases as altitude increases. The mesosphere's temperature decreases as it's altitude increases. This is helpful

Does the stratosphere's altitude increase or decrease?
As we go up in height, altitude increases. Thus the altitude increases.

What happens to temperature once you reach the stratosphere?
The altitude rises.
On what basis do scientists make a distinction between the end of the troposphere and the start of the stratosphere?
For most purposes, it is the point at which temperature begins to increase with altitude.
What is a strong wind in the lower stratosphere?
Jet Stream The main jet streams are located near the tropopause, the transition between the troposphere (where temperature decreases with altitude) and the stratosphere(where temperature increases with altitude)
Is the stratosphere?
The stratosphere is the layer above the troposphere (where we live). The ozone layer is found in the lower stratosphere. The stratosphere is the lowest layer where temperature increases with increasing altitude.
As altitude increases in the Troposphere does the temperature increase?
No, the temperature does not increase in fact it decreases as the altitude increases yes it does.
