because hot air 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. 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.
Raindrops which pass through a layer of freezing air near the ground become sleet.
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.
Air frost - or ground frost
I can give you several sentences.This milk is much fresher than that is.I feel fresher now that I've had a shower and changed clothes.After a rain, the air smells fresher.
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.
In a room with a fire, the air near the fire gets heated and rises. This creates a convection current where cooler air moves in to replace the rising warm air, creating a circulation of air within the room.
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.
During a temperature inversion on a clear night, the air near the ground is cooler than the air above it. This occurs when a layer of warmer air traps cooler air close to the surface, preventing it from rising. As a result, this can lead to the accumulation of pollutants and fog near the ground, as the stable layer inhibits vertical mixing. Inversions can also result in colder temperatures at ground level compared to higher elevations.
