Why is the air pressure greatest at the serface?
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.
How does air above a warm surface move?
Air above a warm surface expands and becomes less dense, causing it to rise. As it rises, it creates a region of lower pressure at the surface, which causes cooler, denser air to be drawn in to replace it. This creates a cycle of air movement known as convection.
Why is airpressure greater near the surface?
Air pressure is greater near the surface because air has mass, which means that the mass of the Earth causes the force of gravity to pull the air towards the surface. This causes the air molecules to compress, which increases air pressure. At the same time, the air molecules want to depressurize, because they are a gas, causing them to physically push on each other. This causes the air pressure closest to the surface to be highest, because the depth of the air above those closest to the surface is greatest. As altitude increases, air pressure decreases for the same reason - there is less mass pushing from above.
How packed is the air the closer you are to the surface?
The air is more packed closer to the surface due to the weight of the air above compressing it. This results in higher air pressure levels near the surface.
How does a flat surface move differently along another one when there's air flowing under it?
What you will notice is what is called Bernoulli's Law. As air passes along between two flat surfaces, pressure increases. If the pressure beneath the top surface increases and surpasses the pressure above it, lift results. Sufficient lift will cause the top surface to rise above the lower.

When air high above the earth' surface is cooled below the dew point it is likely to form?
When air high above the earth' surface is cooled below the dew point what does it form?
Clouds.
When air high above the earth surface is cooled below the point it is likely to form?
Clouds.
When air high above the earth surface is cooled below the dwe point it is likely form?
Clouds.
When the air high above the earth surface is cooled below the dew point is likely to form?
Clouds.
When air high above the earth's surface is cooled below the dew point it is likely to form?
When air high above the earth's surface is cooled below the dew point, it is likely to form clouds or fog. This occurs when the air reaches its saturation point and the water vapor in the air starts to condense into tiny water droplets or ice crystals.
What direction does air above a heated surface move?
in a upward motion
How does heat move between the earth's surface and the air above it?
POOOOOOP
The type of the fog that results when moist air move across a cold surface is?
Advection fog results when moist air moved across a cold surface. When moving across a cold surface, the air is cooled to its dew point.
When air high above the earth surface is cooled below the dew point its is likely to form?
Clouds.
