quite right. Air pressure is the result of millions of air molecules impinging on the surface per unit area. The higher the air pressure, the higher the number of strikes from air molecules.
Yes, molecules closer to the surface experience higher pressure due to the weight of the air above them, making them more densely packed. As you move higher in the atmosphere, there are fewer molecules above exerting pressure, resulting in lower density.
Because as you climb higher there is less air above you pressing down on you with its weight.
Same reason water pressure is higher the deeper you go. There's more stuff above, pressing down. Air has density and weight too.
As you ascend in altitude, air pressure decreases. This is because the density of air becomes lower at higher elevations, resulting in fewer air molecules pressing down from above. Consequently, at higher altitudes, there is less atmospheric weight, leading to lower air pressure. This phenomenon is why mountaineers and high-altitude travelers often experience symptoms related to reduced oxygen availability.
As altitude increases, air pressure decreases. This is because the higher you go, the less air there is above you pressing down. The decrease in pressure with altitude follows a logarithmic pattern, with the rate of decrease slowing down the higher you go.
Atmospheric pressure
At sea level, air pressure is greater compared to higher altitudes. This is because there is more atmosphere above pressing down on air molecules, creating higher pressure. As you ascend in altitude, the air pressure decreases due to the lower concentration of air molecules above.
Yes, molecules closer to the surface experience higher pressure due to the weight of the air above them, making them more densely packed. As you move higher in the atmosphere, there are fewer molecules above exerting pressure, resulting in lower density.
Yes, air pressure is the weight of the atmosphere pressing down on Earth's surface due to the force of gravity pulling the air molecules towards the ground.
Because as you climb higher there is less air above you pressing down on you with its weight.
Air pressure is greatest at the Earth's surface, particularly in the troposphere, due to the weight of the air above pressing down on it. The air molecules are denser near the surface because gravity pulls them closer to the Earth, resulting in higher pressure. As you move higher in altitude, there are fewer air molecules above, leading to a decrease in pressure.
Yes, air pressure is greatest at sea level because the weight of the air above is pressing down with more force. As you go higher in altitude, the number of air molecules above you decreases, causing lower air pressure.
The force exerted by the air on an object is known as air pressure. Air pressure is the result of the weight of air molecules above the object pressing down on it.
When you are at a higher altitude, like on a mountain, you are farther up in the atmosphere meaning there is less air pressing down on you. When you are at a lower altitude, like at sea level, there is more air pressing down on you because there is more atmosphere above you.
Air pressure results from the weight of the air molecules above a given area pressing down. This pressure pushes on surfaces in all directions, exerting a force perpendicular to the surface. The force increases with greater air density and higher elevation.
The average air pressure at sea level is about 14.7 pounds per square inch (psi) or 101.3 kilopascals (kPa). This pressure is due to the weight of the air molecules in the Earth's atmosphere above us pressing down on our bodies.
force = pressure x area , so pressure is force divided by area, air molecules stack up on top of each other and the force of them (caused by gravity and their mass ) weighs down with a pressure of 14.7 lbs/sq inch or 1 bar. As you go higher the stack is lower so the pressure drops until you get to space and it measures a vacuum.
