Most tornadoes are relatively short lived, traveling, on average, no more than 5 miles. The tornadoes that cause major damage typically have longer paths.
Usually, yes.
A cyclone is bigger than a tornado by far, but a tornado is usually more violent.
No. A tornado can't travel that far. Also, unless it is already developing it is impossible to tell exactly where or when a tornado will hit.
The known path length of the Goliad tornado was about 15 miles. The path may have been longer, though, as little is known about what the tornado did prior to hitting Goliad.
Tornadoes get their strength from the storms that produce them. The storms in turn get their energy from instability in the air.
A tornado typically travels 1 to 2 miles in its time on the ground. However some may travel just a fraction of a mile while a rare few travel more than 100 miles.
no
It depends where it is going.
Commercial usually travel below or at 40 thousand - private jets can go 45 thousand
A tornado is usually produced by a type of thunderstorm called a supercell.
Not usually. The median tornado path length is about 1 mile, and only a small percentage travel more than 20 miles. However, a number of tornadoes have been recorded with path lengths well over 100 miles.
usually hundreds if it is a minor tornado but if it is major, usually thousands of people.
