Atmospheric pressure always decreases with height is a TRUE statement.
Explanation:
As the air rises up to high altitudes, the action of condensation and contraction takes place owing to the decreasing temperature with increasing height.
Moreover, the air packets move downwards when they become heavy after accumulating moisture from the atmosphere creating cavities at high altitudes.
Also, the absence of weight that the air needs to stay at heights is responsible for low atmospheric pressures at high elevations.
