Question

In general, atmospheric pressure is greatest near Earth's surface and ____ as you move upward away from sea level. Select one: a. decreases b. increases c. stays the same d. doubles

Answer 1

decreases.....as the heavier molecules gets near earth surface and lighter ones gets above them ..

Answer 2

Option A , decrease

Step-by-step explanation:

The pressure exerted by atmosphere reduces as one moves upward towards the sky. The reason behind this is that the heavy particles in the earth's atmosphere are found in close proximity of the earth's surface due to their heavy weight . The lighter atmospheric particle are found in the upper region of atmosphere due to their low weight and hence as one moves above the surface of earth, the atmospheric pressure reduce.

Hence, option A is correct.
