Pressure is an expression of force exerted on a surface per unit area. The standard unit of pressure is the pascal (Pa), equivalent to one newton per meter squared
Pressure with Height: pressure decreases with increasing altitude. The pressure at any level in the atmosphere may be interpreted as the total weight of the air above a unit area at any elevation. At higher elevations, there are fewer air molecules above a given surface than a similar surface at lower levels
