It moves up because therefore hot air rises and cold air sinks... it would be like evaporation except not because its air.
True. Surface currents can warm or cool the air above them, depending on the temperature of the current and the direction of the wind. Warm currents will typically warm the air above them, while cold currents will cool the air.
Air above a cooled surface tends to sink as it becomes denser and cooler. This creates a downward flow of air which then spreads out horizontally, creating a circulation pattern known as a cold air drainage.
Warm air moves in the atmosphere through a process called convection. As the air near the Earth's surface is heated by the sun, it becomes less dense and rises. This rising warm air displaces cooler air, creating a cycle of movement known as convection currents.
Warm air molecules move by gaining energy and increasing their speed, leading to expansion and becoming less dense than surrounding cooler air. This causes the warm air to rise and mix with the cooler air in a process called convection.
The air pressure is greatest at the surface because the weight of the air above pushes down on the air below, compressing it and creating higher pressure. As you move higher in the atmosphere, there is less air above exerting pressure, so the air pressure decreases.

A temperature inversion is when warm air traps cooler air near the surface, creating a layer of warm air above cooler air. This typically forms on clear, calm nights when the ground rapidly cools after sunset, while the air above remains warmer. This can trap pollutants near the surface and lead to poor air quality.
Warm fronts frequently bring blustery climate as the warm air mass at the surface transcends the cool air mass, making mists and tempests. Warm fronts move more gradually than cold fronts since it is more hard for the warm air to push the chilly, thick air across the Earth's surface.
Air pressure decreases as you move away from Earth's surface. This is because the weight of air above you becomes less as you move higher in the atmosphere, resulting in lower air pressure at higher altitudes.
