How does atmospheric pressure vary with altitude?
A. It increases with altitude
B. It decreases with altitude
C. It remains constant with altitude
D. It varies randomly with altitude
Answer:B
How does atmospheric pressure vary with altitude?
A. It increases with altitude B. It decreases with altitude C. It remains constant with altitude D. It varies randomly with altitude
Explanation: Atmospheric pressure is the pressure exerted by the Earth’s atmosphere at a given point. It decreases with altitude because as the distance from the Earth’s surface increases, the weight of the atmosphere above that point decreases, resulting in a decrease in pressure.
