The air pressure at the top of our heads is the same as the air pressure at any other point at the same elevation above sea level. The air pressure decreases with increasing altitude due to the weight of the air above pushing down on the air below, creating the atmospheric pressure we experience.
There is more air pressure at a beach compared to the top of a mountain. Air pressure decreases with increasing altitude, so the air pressure at the top of a mountain is lower than at sea level like a beach.
On top of a mountain
Air pressure is higher at sea level, such as over the ocean, than at the top of a mountain. This is because air pressure decreases with altitude, as there is less air above to exert pressure. Consequently, mountain tops experience lower air pressure compared to areas at or near sea level.
Actually, air pressure is strongest at lower altitudes, not at the top of a mountain. As you ascend a mountain, the amount of air above you decreases, leading to lower air pressure. This is because the weight of the air column above decreases with elevation, resulting in thinner air and reduced pressure at higher altitudes.
The air pressure is lower at the top of Mount McKinley because there is less air above pressing down on it due to the mountain's high altitude. As you go higher in the atmosphere, the air gets less dense, resulting in lower air pressure.

It decreases. Air pressure is simply the pressure of all the other air on top of it. As you increase in elevation, there is less air on top of you. Therefore, the air pressure is less. As your altitude decreases, there is more air on top of you, therefore, the air pressure increases. Same with water. As you descend, water pressure increases. More on top of you.
There is more air pressure at a beach compared to the top of a mountain. Air pressure decreases with increasing altitude, so the air pressure at the top of a mountain is lower than at sea level like a beach.
The top of a mountain has lower air pressure, not greater air pressure, compared to lower elevations. This is because the higher you go in elevation, the thinner the atmosphere becomes, leading to lower air pressure due to decreased atmospheric density.
There is lesser air pressure on top of the wing when lift occurs. This is due to the shape of the wing causing the air to move faster over the top surface, resulting in lower air pressure according to Bernoulli's principle.
Hot air rises
To pump air into a Presta valve, first unscrew the top cap. Press the pump head onto the valve and secure it. Pump air into the valve until you reach the desired pressure. Finally, remove the pump head and screw the top cap back on to seal the valve.

On top of a mountain
The pressure of the air on one square-inch of your head is the weight of air from that square-inch all the way up to the top of the atmosphere. As you go up in elevation, some of the atmosphere is below you, and there is less of it above you. So the weight on each square inch, and thus the air pressure, becomes less.
The higher you are in the atmosphere, the lower the air pressure. Seeing that the top of a mountain is quite high, the air pressure is low; the air is thinner. This is why you need oxygen tanks to reach the top of Mount Everest
