Faster-moving air exerts less pressure, so there will be force (lift) generated by the air below the object. This is the principle of powered heavier-than-air flight.
The object will have a area of low(er) pressure in top than air underneath, causing lift. This is cause by the air on top being stretched out and having lower density or pressure then the bottom. If there is enough lift to counteract the weight of the object, the object will lift off the ground.

Elevation.
It can be any object that is above or below the horizontal from the perspective of a viewer.
When warm air moving above mixes in with cool air moving below.
These words are used to indicate the position of one object in relation to another. "Above" is used when one object is situated at a higher level than another, while "below" is used when one object is situated at a lower level than another.
"Please place the book above the desk." "The cat is sleeping below the table." "The cup is beside the lamp."
STOP WASTING PEOPLE'S TIME!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
above the wing moving faster above the wing causes a lower air pressure relative to below the wing. high pressure moves to low pressure causing lift.
Solid to Gas - sublimation/depositing occurs at temperatures below 0.01°C. Solid to Liquid - melting/freezing occurs at temperatures above 0.01°C and below 100°C Liquid to Gas - boiling/condensing occurs at temperatures above 0.01°C and is complete above 100°C
The speed of the object reaches a level such that it obliterates the graph above and possibly puts the answer in the box below!
Elevation.
