Answer:
Within the atmosphere, as altitude increases,
A.air pressure stays the same.
B.air becomes heavier.
C.air pressure decreases. The answer.
D.air pressure increases.
Explanation:
That's the question. AND Pressure with Height: pressure decreases with increasing 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. Hope that helps. This means the answer is C.
