Answer» Option 3 is correct - Decreases.. Explanation: Pressure decreases with increase in altitude. The pressure at any level in the atmosphere may be interpreted as the total weight of the air above a unit area at any ELEVATION. At higher elevations, there are fewer air molecules above a GIVEN surface than a similar surface at lower levels. Pressure at a POINT is caused due to the huge mass of air over it. So when we take a point as we go higher, there is lesser air above it,thus air pressure decreases with increase in elevation. This answer may be help you |
