Why is the mesosphere so cold?

Answer 1

The thermosphere is so hot because sunlight strikes this layer of the atmosphere first.

Answer 2

The mesosphere has thin air, and in thin air the molecules are spaced far apart. There are not enough molecules to collide with each other and other things like a thermometer to make it warm. Also, heat takes a long time to rise up to this level anyway. This accounts for it being so cold.

Answer 3

Well to start off, cold air is denser than hot air. When the air is near the surface of earth it is heated up due to the warmth of the earth's core, and since we all know hot air rises, it will do exactly that, rise. Once it reaches a high enough altitude it will then cool off and become more dense. Then that cold, dense air will be floating along top the hot, rising air. That is why the air in the mesospheric layer is cold.

Answer 4

The mesosphere is cold because it is the layer of the atmosphere located above the stratosphere. This region experiences very low temperatures because it is located higher in the atmosphere where there is less air to trap heat from the sun. Additionally, the thin air in the mesosphere allows the little heat present to escape easily into space, contributing to its cold temperatures.

Answer 5

It is so hot here because nitrogen and oxygen in the atmosphere absorb a lot of radiation from space and convert it to heat.

Answer 6

this is because of temperature inversions as the altitude goes up the temperature goes down. so the coldest part really is the top of the mesosphere.

Answer 7

Uhhh... it's a toughie but it's ... YO MAMMA

Answer 8

because the mesosphere's air particles are further apart which makes it harder to hold in heat so it makes it colder

Answer 9

because
