It is unlikely. An F5 tornado can gouge out the ground to some depth, but not deep enough to reach most buried coffins.
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.
Nothing special. All tornadoes stretch from cloud base to the ground. If the vortex doesn't reach cloud base or the ground it isn't a tornado.
The funnel of a tornado always connects to cloud base and typically all the way to the ground (the circulation of a tornado can reach the ground even if the funnel does not). Cloud base height is variable but in a tornado supercell is usually about 3000 feet to a mile above the ground. The circulation of the tornado usually goes a great distance above cloud base and can reach heights of more than 4 miles.
To some extent, yes. A funnel cloud is the visible portion of a tornado. However, not all funnel clouds are tornadoes. If the winds associated with a funnel cloud do not reach the ground then it is not a tornado. Conversely, if the winds do reach the ground the term funnel cloud is not usually used, and the event is simply called a tornado.
A rotating column of air is known as a whirlwind. If it is violent and connects to both the ground and the cloud base of a thunderstorm, it is considered a tornado.
One tornado is reported to have had a damage path only seven feet long. It was likely on the ground for less than a second.
no it is not legal. If you take something of of the ground it is rightfully someone else's and now, even though they had lost it, they have no access to it at all.
By definition a tornado must be in contact with both the ground and the cloud base. So, in that sense, yeas. But this only means that the violent circulation must make this connection, not necessarily the visible funnel. Additionally, sometimes a tornado starts to form, but dissipates before touching down, but in that case it is not considered a tornado.
A tornado creates an area of low barometric pressure. Air spirals into the tornado and then spirals upward within it. The low pressure in a tornado cools air flowing into it, causing moisture to condense into the characteristic funnel. In many cases, though not all, the condensation reaches all the way to the ground.
All funnel clouds touch the clouds. A funnel cloud that touched the ground is called a tornado.
The process of tornado formation starts when wind shear starts the updraft a a thunderstorm rotating, turning it into a supercell. If the right kind of down draft, called a rear-flank down draft occurs it can wrap around the rotating updraft, which is called a mesocyclone, and turn it into a more intense circulation: a tornado.
The word is spelled cemetery, with all "e"s in it.
