Yes, in fact a thunderstorm is the only thing that can produce a tornado.
Seek shelter on the lowest floor of a building, go to a central closet or bathroom, or lie in a ditch (if outdoors ONLY).
There is no such thing as a F10 tonado. It only goes up to a F5.
Bathroom is safe only if it is located in a basement, but otherwise, I'll strongly recommend a basement which is supposed to keep the tornadoes out, if you are in an area where tornadoes tend to come.
Just like a male does only they sit down. Why do they sit down instead of standing up like a man does?
It was a tornado. That's the only thing the Fujita scale is used to rate.
There is no such thing as an F8 tornado. The scale as it works only goes up to F5 since it is based on damage rather than wind speed. However, theoretical winds in an F8 tornado would be 446-514 mph. Such winds are not thought to be possible in a tornado.
The short answer is: you can't. A tornado will probably destroy even a tied-down mobile home, so if a tornado is coming toward your mobile home, the only thing to do is run for it.
There is no word, but SRO (standing room only) means the same thing.
Yes, a severe thunderstorm can create the conditions necessary for a tornado to form. Thunderstorms with strong updrafts and rotation can produce tornadoes when other factors align, such as atmospheric instability and wind shear.
A bathroom is not your only other option during a tornado. Any interior room, closet, or hallway on the lowest floor can protect you. Even getting under a bed can offer protection. Another option is to go to a nearby sturdy building, or some other nearby structure where you can get underground. If you live in a mobile home, you should definitely leave it for more substatial shelter.
There is no such thing as an EF6 tornado. Estimated winds for an EF5 tornado start at just over 200 mph and have no upper bound.
