Neither. A funnel cloud that touches the ground is a tornado. A thunderhead is the sort of cloud that develops into a thunderstorm, and a supercell is the kind of thunderstorm most likely to produce a tornado.
A tornado that touches the ground is simply a tornado. Before it touches down it is called a funnel cloud.
No. It is called a funnel cloud. However, tornadoes are produced by thunderstorms.
That is the model agreed upon by most scientists. There is some evidence, though, that some tornadoes may form from the ground up. Scientists are still unsure what to make of this.
It can take anywhere from just a few seconds, to several minutes, if the funnel cloud reaches the ground at all.
Yes and no. The funnel of a tornado does not have to reach the ground for damaging winds to occur at ground level. However, if those winds reach the ground then the tornado has touched down even if the funnel hasn't.
Before a tornado touches down it is called a funnel cloud, which looks like a tornado but does not reach the ground. A funnel cloud develops from the mesocyclone of a supercell thunderstorm. A supercell thunderstorm is characterized by the presence of a mesocyclone, which is a deep, continuously-rotating updraft.
When a funnel cloud touches the ground it becomes a tornado.

A funnel shaped cloud is called a funnel cloud. If it touches the ground it is called a tornado.
A funnel cloud is a condensation funnel made of water vapor, dust, dirt, and debris lifted upward from the ground in areas experiencing extremely low air pressure. It is the visible part of a tornado and is considered a tornado if it touches the ground.
A tornado that touches the ground is simply a tornado. Before it touches down it is called a funnel cloud.
All funnel clouds touch the clouds. A funnel cloud that touched the ground is called a tornado.
