Question

why does atmosphereic pressure changes with increasing altitude

Pranay Kumar · Accepted Answer

Solution :
The atmospheric pressure varies with altitude as the density of air
decreases as we rise up and the air becomes rarer

Atmospheric pressure decreases with increases in altitude
As we know that the density of air becomes heavier near the
surface of the earth (due to gravity) and begins to lighten as we
go to higher altitudes and eventually leads to empty space, i e
outside the atmosphere of the earth
Thus, the atmospheric pressure is high at lower altitudes, the
density being higher The atmospheric pressure is low at higher
altitudes, the density being lower
