No. While most tornadoes rotate in a direction that matches earth's (clockwise in the northern hemisphere and counterclockwise in the southern), a small percentage go against this. The origin of the spin in tornadoes is not directly related to earth's rotation. Most tornadoes also move in an easterly direction, but not always.
About 44.4%. So mesocylones don't always mean tornadoes.
Yes, but they are nearly always weak.
Tornadoes always happen during thunderstorms. They cannot occur without them.
Yes. Or at least there have probably been tornadoes for as long has Earth has had approximately the same atmosphere that it has now.
No. Tornadoes almost always rotate clockwise in the southern hemisphere. Counterclockwise tornadoes are in the northern hemisphere.

Tornadoes nearly always spin counterclockwise if they are in the northern hemisphere and clockwise if they are in the southern hemisphere.

Big tornadoes are usually strong, but not always. A large, poorly organized tornado is not likely to be very strong. Some tornadoes even weaken as they expand.
No. Tornadoes usually come out of the west or southwest, but they can travel in any direction.
Very often tornadoes, will travel in a straight line, but many do not, following meandering or curved paths instead.
Yes, but they are nearly always weak.
No. Tornadoes are fairly rare in California and they are almost always weak. That said, a few tornadoes have occurred in the LA area.
All tornadoes are dangerous. Wedge tornadoes are usually stronger and thus more dangerous than smaller tornadoes, though this is not always the case.
