Pressure is _____ proportional to altitude.(a) inversely(b) directly(c

1.	Pressure is _____ proportional to altitude.(a) inversely(b) directly(c) no relation(d) equalThis question was addressed to me in quiz.I'd like to ask this question from Pressure Coefficient topic in division Inviscid & Incompressible Flow of Aerodynamics
Answer» The correct CHOICE is (a) INVERSELY The explanation is: PRESSURE is inversely proportional to altitude. As altitude increases, pressure decreases and vice versa because the air molecules are pulled DOWNWARDS due to the gravitational force of the earth and hence, all the molecules are close at lower altitude thus generating higher pressure at lower altitudes.
