Black body radiation is stactic in that it depends only upon the temperature of matter. Heat transfer by conduction is also static. Heat transfer by convection could be call dynamic heat conduction. In it's own way it is also static. I expect you cannot comprehend my use of the word static.

5.6 KM is a good average point where under certain condition one knows that air pressure is 50% of the defined 1 atmosphere. 70% of the earth is covered by water. And in that there is no measured change in the lapse rate, adjusting for elevation would be an insignificant amount of mass added to the blocking above totals.
Yes the 50% point varies with pressure and temperatures around the globe. So you could say from 5km to 6.2 km as a band where the 50% point of pressure and thus mass is divided equally above and below.
Your questioning of my use of 5.6 KM would suggest a extensive ignorance scientific nomenclature.

you may have majored in physics and you may even have a degree which proves you were able to tell you professors what they wanted to hear from the lectures you attended. A degree is no proof you understand or have internalized correctly the true meanings of the laws of physics.

My own understanding of physics was not from my courses attended getting my EE degree. It is from my natural curiosity and continuous quest of finding out how things work.

My quest for how it works started in my youth partly with this home study guide and my decades of engineering work.

The standard atmosphere (symbol: atm) is an international reference pressure defined as 101325 Pa and formerly used as a unit of pressure. [1] For practical purposes it has been replaced by the bar which is 100 kPa. [1] The difference of about 1% is not significant for many applications, and is within the error range of common pressure gauges.
