Gravity causes air to rise

WebWhen we studied mid-latitude cyclones, you saw a number of mechanisms that cause air to rise, such as overrunning and low-level convergence along a cold front. But, these mechanisms that cause rising air result in fairly slow upward motions, often roughly a few or several centimeters per second (at most maybe 10 to 20 centimeters per second). WebJun 4, 2011 · The true reason that heat rises is due to something not yet mentioned... GRAVITY! To be more precise, in a positively excited atom/molecule, the electrons create a larger orbital shell whereby...

WebThe mechanism responsible for the rising of hot air is flotation: Hot air is less dense than cold air and hence air pressure will exert an upwards force, in the same way air rises in water. Now if cold air was magically unaffected by gravity, then it would not be able to exert pressure on the hot air and thus it would not rise. WebAs air pressure decreases, the density of the air decreases. So density decreases as altitude increases. Since the air is less dense at a high altitude, there are fewer air … facebookcampusk9 https://lconite.com

WebMay 18, 2024 · The model suggests that, as tropical climates warm, the effect could increase exponentially, meaning that the region would let off more and more heat, even as temperatures rise. WebGravity's role is its pull of cooler, denser air toward the earth's surface. As the denser air reaches the earth's surface it spreads and undercuts the less dense air which, in turn, forces the less dense air into motion …
