Yes. Tornadoes do not occur in Antarctica and likely do no occur in parts of the Arctic and in areas of extreme desert. There are many other regions that are cold or arid that tornadoes occur, but are extremely rare.

If there are 28 handshakes in a room, there must be 8 people present. Each person shakes hands with every other person once, so the total number of handshakes can be calculated using the formula n(n-1)/2, where n is the number of people in the room. Solving for n in this case gives you 8 people.

the first shakes 8 people's hands (remember, not his own), the second 7 (he doesn't shake the first one's hand), then the third shakes six, the fourth shakes 5, the fifth shakes 4, the sixth shakes 3, the seventh shakes 2, and the 8th shakes the 9ths hand so 8+7+6+5+4+3+2+1 = 36
36. Everybody shakes 8 hands but each shake counts for 2 people. So 9*8/2=36.
