Explain with examples how atmospheric pressure varies with altitude. What kind of weather changes are indicated by variations in atmospheric pressure? What are different applications of atmospheric pressure?
Atmospheric Pressure and Altitude: Atmospheric pressure refers to the weight of the air above us. As altitude increases, atmospheric pressure decreases. This happens because the density of air becomes lower as you ascend, and fewer air molecules are present above you to exert pressure. The decrease in pressure is roughly exponential, meaning it drops more … Read more
