Answer:
Air pressure:-
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.One atmosphere is 1,013 millibars, or 760 millimeters (29.92 inches) of mercury.
Pressure Belt:-
Pressure belts are seasonally identical horizontal pressure variations created in the earth's atmosphere just above the earth's surface due to seasonal and spatial variation of energy received by the earth at different places.This low pressure belt extends from 0 to 5° North and South of Equator.
