The pressure difference works this way. You literally have more air molecules in a given area, a "high" pressure front. The air wants to reach equilibrium, so it flows to a "low" pressure, or less air molecules in the same given area, front. What you feel is air molecules moving from one area to another, or wind.
the earths surface.
Pressure
Its the hydrosphere
The convection cells radiate heat.
The particles outside the Earths atmosphere are called, meteoroids.
the earths surface.
The earths winds
the earths surface.
autmospheric pressure
well the suns pressure and the earths atmosphere
The weight.
Pressure
The two are completely unrelated.
Atmospheric pressure is caused by the force of the air above the earths surface. It is measured by the point in which the air meets the atmosphere.
Airplanes are used for transportation within the earths atmosphere where as spaceships are for travel outside and eventually back into the earths atmosphere
An aircraft flies in the Earths atmosphere, whereas a spaceship flies above the atmosphere.
Yes. Atmospheric pressure is the pressure caused by air when it exerts pressure on the surface of earth.
