Question

Question Completion Status: Model - Atmospheric Pressure Atmospheric pressure arises from the force exerted by the mass of air above a certain amount of area at the surface of the Earth. For example at sea-level the force exerted by the air above each square inch (in?) of surface is approximately 14.7 pounds, In the graphic to the right, each square cokumn represents an equal surface area but at different alttudes: sea level, a mountain peak and part-way up the mountain. Measured from the center of the Earth, the height of the atmosphere is nearly constant AtmosphericI Height What will be the relative atmospheric pressure at each of the three alitudes represented in the graphic, if the area covered by each column is the Ses level A Lowest pressure B. Highest pressure. C Iintermediate pressure D None of the other answers are applicable. Mountain peak Part way up a mountan QUESTION 2 0

Explanation / Answer

Sea level - highest pressure

Mountain peak - lowest pressure

Part way up a mountain - intermediate pressure

On moving towards the elevation, air pressure decreases because less amount of air pushes down on you and the particles of air are very far apart.
