**PLEASE ANSWER ASAP**

Which of the following statements about Earth's atmosphere is true?

a) The atmosphere exerts greater downward than upward pressure.

b) Pressure is highest in upper areas of the atmosphere.

c) Atmospheric pressure increases as altitude decreases.

d) Pressure is equal at all levels of the atmosphere.

Answer 1

I can confirm that. Mm-hmm.

Answer 2

A

Step-by-step explanation:

Air lower in the atmosphere is more dense than air above, so air pressure down low is greater than air pressure higher up. (Remember those acrobats; there's a lot more pressure on the one on bottom than on the one on top.) Temperature also makes changes in air pressure.
