Why does air temperature decrease with increasing altitude?

REACTIONS OF ELEMENTS

It is colder the further out we go when we head upward from our planet, in the direction of 'further away', or 'up higher' and therefore closer to our Outer Space.

Our lower layer called the 'Troposphere', closet to us in our air (Atmosphere,) is warmer, because there is interaction with the Infrared Ray from the Solar Rays within the Earth's Core. Heat rises. We... get hot! This layer is +- 8km.

So if they need oxygen masks alone to climb to the summit of Mt. Everest at only 880 + meters (29 ,000+ feet,) As this +- 8.8 kilometers, how high is cold and thin air before we either can die of exposure? Due to the cold and the lack of oxygen... they even have a 'death zone'! It's bad enough with altitude sickness... All these are the reasons why air temperature decreased with the increase of altitude?

Then comes the 'upper Troposphere' - another layer of almost 9km, and we have now reached a height of 17km. up. It is in the Troposphere where our weather occurs. This is already showing change... from whips of clouds to where the negative and positive charges of electricity in the air react, creating storms.

The 'Troposphere' is approximately half of our earths Atmosphere. The outer regions just as the inner, all have their reaction on the other. From the core of our earth to the furtherest reaches of this (and beyond,) there is a blending of the elements within the Atmosphere.. Each give 'rise' to their change of state on the other; just as all chemicals have different reactions.

Climbing higher, we come to the lower 'Stratosphere' layer, just over 13 and a half kilometers further out... now we are getting closer to cooling off even more. This is where our jets mostly show the colder air, through what we call their trail of white vapor - jet stream - just as when we are in the cold, our breath shows vapor. When our body air meets the colder outside air which we breath. For those who have traveled in a jet, we also know we are well up to 'minus' 30-40 C. degrees. That's cold!

With all these different elements reacting; as for a human beings go, we need the air-tight air-craft to protect us; just as we do down in the the Atmospheric Pressures of the deep in the Oceans of our earth. Rising higher we are now at a height of 30 + kilometers... where weather balloons go.

But this sphere doesn't change until at least 60 km. up and out; and it is here in this 'Stratosphere' where our 'Ozone Layer' is, where our main
