Atmospheric pressure is greatest near the Earth's surface becauseGroup of answer choicesof water vapor.of warmer temperature.90% of Earth's atmosphere is in the troposphere.of the weight of all the air above.Next

A scientist uses a mercury barometer to measure the atmospheric pressure at the top of a mountain. He finds that the height of mercury in the column is lower than it is at sea level. Which of the following best explains this finding?A.The atmosphere exerts more force on the mercury at the top of the mountain than at sea level.B.Due to the height, the force of gravity is stronger at the top of the mountain than at sea level.C.Mercury behaves as a more dense substance at the top of the mountain than it does at sea level.D.The atmosphere weighs less at the top of the mountain than it does at sea level.
