The force exerted by the weight of a column of air on a surface is called air pressure. It is commonly measured in units such as pounds per square inch (psi) or pascals (Pa).
The push of air on the Earth is called atmospheric pressure. It is the force exerted by the weight of the air above a given point on Earth's surface.
Yes, sea water does weigh more at depth than at the surface due to the increased pressure exerted by the water column above it. This pressure causes the water molecules to be more densely packed together, resulting in a higher weight per unit volume.
A column of air exerts atmospheric pressure on the air or surface below it. This pressure is caused by the weight of the air above pushing down on the lower air or surface.
When air particles press down on Earth, they create atmospheric pressure. Atmospheric pressure is the force per unit area exerted on a surface by the weight of the air above it. This pressure decreases with elevation due to a decrease in the density of the air column above.
The weight of the air pushing down on Earth's surface is due to air pressure, which averages around 14.7 pounds per square inch (psi) at sea level. This pressure is caused by the force exerted by the weight of the air molecules in the atmosphere above.
