Want this question answered?
The tornado is a twister before it hits the ground, it just spins in the sky, kind of
Because when an object is sliding on the other the molecules donnot get time to inter lock properly
yes it can also reduce friction especially when its slippery, cleats reduce the surface area that are in contact between the shoes and the ground surface?
It is only when the circulation reaches the ground that it is considered a tornado. Prior to that it is merely a funnel cloud.
Wind at the surface is slower than the "winds aloft" The biggest effect is within a few inches of the ground.
it stays on the ground until it weakens

The wind at the surface of the ground where the molecules are having friction is moving slower than the wind above the surface.
Yes, a tornado is not considered a tornado unless it reaches the ground.
Yes, normally this happens to planes on the ground when a tornado strikes an airport.
Ice has a much smoother surface than the surface of the ground, therefore there is less friction acting on the hockey puck compared to a ball rolling on the ground. Ice is nearly a frictionless surface.
Air at ground level will then spiral into the tornado and reach great speeds. Any buildings or trees the tornado hits will be damaged or destroyed by the winds.

It depends what you call a tornado. Most tornado-like clouds do not touch the earth's surface. Some say that until it touches the ground it is not a tornado but a funnel cloud; however the definition of a tornado does not state that it must touch the ground. It all depends on what you're taught.

Friction depends on the surface that the object is going against. If an applied force is used to push a box on a ground, the friction is the surface of the ground, may the ground be rough or smooth, there is a force that goes against the applied force. Air friction is also a type of friction that many physics question does not account for, because it is a virtually small force.
it will be slower near the surface
