Question

what is meant by atmospheric pressure ?? what is the cause of atmospheric pressure?? don't spam please.......​

Answer 1

Answer:

The type and intensity of weather is controlled by changes in air pressure. Air pressure is caused by the weight of the air molecules above. ... This pressure causes air molecules at the Earth's surface to be more tightly packed together than those that are high in the atmosphere.

Answer 2

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. Atmospheric pressure is commonly measured with a barometer. In a barometer, a column of mercury in a glass tube rises or falls as the weight of the atmosphere changes.

At sea level, standard air pressure in millibars is 1013.2. ... This change in pressure is caused by changes in air density, and air density is related to temperature. Warm air is less dense than cooler air because the gas molecules in warm air have a greater velocity and are farther apart than in cooler air.
