How does the standard atmospheric pressure exhibited at sea level compare to the atmospheric pressure exhibited at the top of a tall mountain? A) It is higher than the atmospheric pressure at the mountain elevation. B) It is the same as the atmospheric pressure at the mountain elevation. C) It is lower than the atmospheric pressure at the mountain elevation. D) This cannot be determined from the information given.
I'm pretty sure its A...can someone tell me if im right?
Well, think of the atmosphere as a column of air (which doesn't weigh a lot, but does have some weight). If the top of the column is the same height everywhere, the column squashing you on top of a tall mountain will be somewhat shorter than the one squashing you down at sea level -> less weight.
So A should be correct
