pressure =force/ area
pressure of a liquid is density time height.
The upward force due to a pressure difference is called lift. It is generated when the air pressure below the wing is higher than the pressure above the wing, creating a pressure difference that causes the wing to be pushed upward.

Oil is under pressure underground, and when a well is dug into an oil trap, the release of this pressure causes the oil to shoot upward. This natural upward flow is driven by the difference in pressure between the oil reservoir and the surface.
If the air moves faster above an object, it creates a lower pressure area. In response, the higher pressure beneath the object will push it upward. This mechanism is known as lift and is how airplanes generate the force needed to fly.
If the air moves faster below an object, the pressure is lower compared to the pressure above the object. This pressure difference creates lift, causing the object to be pushed upwards.
Air pressure exerts a vertically upward force on a ceiling due to the weight of the air above pushing down on the air below. This pressure difference results in a net force that pushes upward on the ceiling, according to Newton's third law of motion.
The wing generates lift, which propels the aircraft upward due to differences in air pressure on the upper and lower surfaces of the wing. So, the wing is being pushed upward.
The term that describes the upward force on the wings of an airplane that causes unequal pressure is lift. This lift is generated by the flow of air over the wings of the airplane, creating a pressure difference between the upper and lower surfaces of the wing, resulting in the upward force.
This is a vector measurement.
Pressure is the weight of air column on unit area. As you go upward, this air column gets shorter, its weight gets less, hence air pressure gets lower.
Buoyancy is not directly caused by pressure. Buoyancy is the upward force exerted on an object immersed in a fluid, such as water, due to the pressure difference between the top and bottom of the object. This pressure difference results in the object experiencing a net upward force, causing it to float or rise in the fluid.
