no mid air in the sky says the scientist from steefal areobotics
New answer. I'm not sure who the scientist from steefal areobotics is or where he got his information but the air is thinner the higher you go in altitude. At sea level the atmospheric pressure is 14.7psi and as you increase the altitude the air pressure becomes less and less. There is 78%nitrogen, 21%oxygen and 1% other inert gases in the atmosphere and that reamins constant but as the air thins out the gases are spread farther apart making the air thinner. When you go up in a jetliner you wouldn't be able to breathe without having the aircraft cabin pressurized. They pressurize the cabin to about the same atmospheric pressure as you would find at 8000 feet and that allows you to breathe without having to add oxygen.
clouds
fog
Fog is a type of cloud that forms near the ground. It occurs when air near the surface cools to the point where it can no longer hold its water vapor, causing it to condense into tiny water droplets.
When air is cooled to the dew point near the ground, it forms a stratus cloud called fog. Fog is a type of low-lying cloud that reduces visibility at the Earth's surface.
Fog is a type of cloud that forms close to the ground when the air near the surface becomes saturated with moisture. It reduces visibility and can be created by cooling air or adding moisture to it.
air near the ground becomes warm and expands.warmer air is less dense than cold air and therefore the warm air near the ground rises. air near the ground becomes warm and expands.warmer air is less dense than cold air and therefore the warm air near the ground rises.
Cool air rushes in to replace the rising warm air.
near the equator, where the warmer temperatures lead to greater vertical expansion of the air.
Raindrops which pass through a layer of freezing air near the ground become sleet.
because hot air rises
Air frost - or ground frost
When a tornado funnel touches the ground, the air near the surface rushes inward at high speeds and begins to rotate rapidly. This rotation causes the funnel cloud to extend downward, allowing the tornado to make contact with the ground and causing destruction in its path.
Ventilators are typically placed near the ceiling because hot air rises, so they can effectively circulate and distribute air throughout the room. Placing them near the ground would not be as efficient in terms of air circulation and distribution.
clouds
This process typically creates convection currents, which can result in the formation of breezes or winds as the warm air rises and cooler air moves in to take its place. This movement of air helps to distribute heat energy and regulate temperatures on the ground.
As air near the ground is warmed by sunlight, it becomes less dense and rises. This creates an upward motion of air, which we commonly call convection. This process can lead to the formation of clouds and ultimately to the development of thunderstorms.
When air is cooled to the dew point near the ground, it forms a stratus cloud called fog. In foggy conditions, visibility is significantly reduced due to the water droplets suspended in the air near the surface.
