Question

Give a detailed account of air pressure in atmosphere. Please fast. No spam answers, any will be deleted on the spot. And no asking from google.

Answer 1

Hey ,

Answer:

That pressure is called atmospheric pressure, or air pressure. It is the force exerted on a surface by the air above it as gravity pulls it to Earth. And the atmospheric pressure is measured with a barometer .

Explanation:

Atmospheric pressure is caused by the gravitational attraction of the planet on the atmospheric gases above the surface, and is a function of the mass of the planet, the radius of the surface, and the amount and composition of the gases and their vertical distribution in the atmosphere.[2][3] It is modified by the planetary rotation and local effects such as wind velocity, density variations due to temperature and variations in compositionAtmospheric pressure varies widely on Earth, and these changes are important in studying weather and climate.

Hope this can help

Have a good day

Answer 2

Answer:

Atmospheric pressure is the pressure within the atmosphere of Earth.

The Earth's atmospheric pressure at sea level is approximately 1 atm.

As elevation increases, there is less overlying atmospheric mass, so atmospheric pressure decreases with increasing elevation.

Pressure measures force per unit area, with SI units of Pascals (1 pascal = 1 newton per square metre).
