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

Option A , decrease

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.

an adaptation is a change or process by which an organism takes to be better suited for its environment. for example; migration is a behavioral adaptation, this is needed because birds are not built to last extremely cold climates. there are different adaptations because there are different species needing to adjust to different things, bears don't migrate; they hibernate.
