Question

How do you write the orbital diagram for phosphate?

Answer 1

Atmospheric pressure decreases as the height of surface above the ground level increases this is because of the increase in altitude and the number of the air molecules decrease. There is less air above the surface. The pressure at any level in the atmosphere may be interpreted as the total weight of air above the unit of area at any given elevation. At the relevant higher elevation there are few air molecule above the given surface is than a similar to the surface at levels which are lower.So as we go up at higher altitude we can see change in pressure decrease

Complete answer:
We know that the above sea level atmospheric pressure in the troposphere drops by $1$ inch mercury for each and every thousand feet of altitude.The Gravity of Earth holds our atmosphere close to the surface, which results in density and pressure. So air gets gradually lower and if we go to a higher altitude. Also at sea level atmospheric pressure is $30$ inches mercury, and this rate decreases at rate of approx. $1\text{ }inch$ for every $1000$ feet of altitude above sea, so at altitude of $4000ft$, the pressure is approx. $26\text{ }inch$ mercury.
The troposphere is where effects of weather are the most important part and the actual pressure depends on temperature and the presence of high and low pressure weather systems. Temperature change with the altitude in complicated way that is why the $\dfrac{1inch}{1000feet}$Similarly when the airplane fly in the our troposphere, the pilot receive the barometric pressure correction from control Centre this are called Altimeter Settings, which in result compensate for local change in pressure and temperature, so that the planes can fly at a consistent of the altitudes. The altitudes are not always accurate at higher altitudes but they are designed to be highly accurate so near the ground that the landings are safest.

Note: The air is in denser form in this lowest layer. In fact, we also know through this that the troposphere contains three quarters of mass of the entire atmosphere. The air here is always $78$ nitrogen and $21$ oxygen. The last thing is $1$ and made of argon, carbon dioxide, and Water vapor
