Air pressure is gravity pulling down on air molecules. Like us,
air has also mass and the pressure is brought down by the earth’s gravity
causing an increase in weight exerted on you as you descend lower into the
atmosphere. So, as you enter into the other layers of atmosphere above the troposphere,
the air pressure starts to decrease. Below the atmosphere is the hydrosphere. This is
where all liquid forms are located. And since the seawater has a greater mass
than air, it has the greatest pressure. The answer is true.
