Total mass of atmosphere: 5.1 x 1018 kg
Another calculation has as result 5.4 x 1018 kg
Atmospheric pressure varies over Earth's surface, mainly due to differences in temperature, altitude, and weather conditions. This variation in air pressure creates different weight of air known as atmospheric weight.
it is a branch of atmospheric science which deals with chemistry of the earths atmosphere
The troposphere.
rotation
Venus and Mars. The difference is that Venus atmospheric pressure is around 93 times that of Earths, while Mars' atmospheric pressure is only 0.7% of Earths.
It decreases as you move away from the earth surface
Pressure
The weight of the air on Earth's surface is approximately 14.7 pounds per square inch (psi), or 101.3 kilopascals (kPa). This pressure is due to the force exerted by the column of air above us, known as atmospheric pressure.
How are atmospheric gases like the glass in a greenhouse
The atmospheric layer closest to the Earth's crust is the troposphere. It is where we live and where most weather phenomena occur.
Atmospheric pressure is the weight of the air.
The troposphere is the atmospheric zone that covers approximately 70% of the Earth's surface. It is where most weather phenomena occur and where the majority of Earth's atmospheric gases are found.
