They stay the same :)
Air pressure decreases as temperature increases, and air pressure increases as temperature decreases. This is because warmer air is less dense and exerts less pressure, while cooler air is denser and exerts more pressure.
The density is greater at the lower mantle due to the increase in pressure and temperature as you move towards the Earth's core. This denser material sinks while the less dense material rises, driving the process of mantle convection that helps drive plate tectonics.
Air pressure is greater at sea level because there is more air above that is pressing down. Any atmosphere is more dense at the surface of the planet than at locations higher in altitude. (Areas that are lower than sea level will generally have still higher atmospheric pressure.)
Yes, the weight of the air exerts pressure on the Earth's surface, creating atmospheric pressure. This pressure decreases with altitude as the air becomes less dense.
In the troposphere, as air temperature increases, air pressure generally decreases. This is because warmer air is less dense and exerts less pressure on its surroundings compared to cooler air.
The further down you go the more pressure is exerted upon that point by the sum of the weight ( gravity and density) of the substance (usually water) above that point (the height or depth). For example, if their where say more argon than there is now in the atmosphere the barometric pressure would be higher when ignoring the changes in pressure due to weather.
If you were submerged in a liquid more dense than water, the pressure would be correspondingly greater. The pressure due to a liquid is precisely equal to the product of weight density and depth. liquid pressure = weight density x depth. also the pressure a liquid exerts against the sides and bottom of a container depends on the density and the depth of the liquid.

Standing on tip toe exerts greater pressure on the floor compared to standing flat footed. This is because less surface area of contact between the feet and the floor means the body's weight is concentrated on a smaller area, resulting in increased pressure.
The two factors that determine the pressure a fluid exerts are the depth of the fluid and the density of the fluid. Pressure increases with depth as the weight of the fluid above creates more pressure. Additionally, denser fluids will exert more pressure compared to less dense fluids at the same depth.
Water is denser than air, meaning there are more water molecules in a given volume than air molecules. This greater density of water results in more molecules colliding with the surface, creating higher pressure. Additionally, water is less compressible than air, so changes in volume have a more pronounced impact on pressure.

Air pressure decreases as temperature increases, and air pressure increases as temperature decreases. This is because warmer air is less dense and exerts less pressure, while cooler air is denser and exerts more pressure.
There is less air higher in the sky so the pressure is less. At sea level, all the air above a certain space exerts pressure. There's also more air, so the pressure is greater. Like any material, air becomes heavy in large enough quantities.
Buoyancy is the factor of things that float or sink. Density is related because if the object has more density than water, it will sink. But, if it has less density than water, the object will float.
