why does the pressure decreases as the altitude increases?
Asked by | 04 Oct, 2012, 08:54: PM
answered-by-expert Expert Answer
the air pressure is due to the weight of the air above us.
Since as we go up,the amount of air above us decreases and thus the air pressure decreases.

CBSE 9 - Physics
A boy throws a steel ball straight up. Consider the motion of the ball only after it has left the boy's hand but before it touches the ground and assume that forces exerted by the air are negligible. For these conditions, the force(s) acting on the ball is (are): a. A downward force of gravity along with a steadily decreasing upward force b. A steadily decreasing upward force from the moment it leaves the boy's hand until it reaches its highest point on the way down there is a steadily increasing downward force of gravity as the object gets closer to the earth c. Constant downward force of gravity along with an upward force that steadily decreases until the ball reaches it highest point on the way down there is only a constant downward force of gravity d. Constant downward force of gravity only
