Temperature is the average amount of energy that a (air) particle has. Pressure is the force that the moving particle exerts as it bumps into or pushes against a surface. The higher the temperature, the faster the particles will be moving and the more force they will exert when they bump into a surface. So as temperature goes up, so does pressure.
The air pressure difference between the equator and the poles is primarily caused by the temperature difference. Warm air at the equator rises, creating a low-pressure area, while cold air at the poles sinks, creating a high-pressure area. This temperature difference drives atmospheric circulation, resulting in the pressure gradient between the two regions.
Air flow is initiated when there is a difference in air pressure between two points. Air moves from areas of high pressure to areas of low pressure to equalize the pressure. This can be caused by various factors such as temperature gradients, fans, wind, or the movement of objects through the air.
When there is a great difference in air pressure between two areas, winds are strong. The air moves from high pressure to low pressure, causing faster winds to equalize the pressure difference.
Flowing air responds to the difference in pressure between higher and lower pressure areas by moving from high pressure to low pressure to equalize the pressure. This movement of air creates wind, which is the result of the pressure difference seeking equilibrium.
The main difference between the air below and above the wings of a plane in flight is the air pressure. The air below the wings has higher pressure, while the air above the wings has lower pressure. This pressure difference creates lift, allowing the plane to stay in the air.

No.
Creating a bigger temperature difference between the poles and the equator leads to a stronger pressure gradient force in the atmosphere, driving stronger winds. This temperature difference causes air to move from high pressure to low pressure areas, resulting in faster wind speeds. The Coriolis effect also plays a role in shaping wind patterns based on the Earth's rotation.
The difference in pressure between absolute and gauge pressure.
When cool air tries to replace warm air, it creates wind. This movement of air occurs due to the difference in temperature and pressure between the two air masses, leading to the flow of air from high pressure (cool air) to low pressure (warm air) areas.
Temperature differences is why air moves in the atmosphere. Hot air rises, cold air falls. With these temperature difference comes pressure differences and these temp. and pressure differences are what keep the air moving. Theoretically, if there were no temp. or pressure differences in the atmosphere, air would not move.
The difference is that Low air pressure has less air molecules pushing down in one area and high air pressure has more air molecules pushing down in one area.
