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.
There are seven elements that occur naturally as diatomic molecules: hydrogen (H2), nitrogen (N2), oxygen (O2), fluorine (F2), chlorine (Cl2), bromine (Br2), and iodine (I2).
Elements 1-92 except 43 (technetium) and 61 (promethium) occur naturally. So, there are 90 naturally occurring elements.
If there are seven people, then the number of handshakes is 7*6/2 = 21

105 ( First person shakes 14 different hands, second shakes 13 etc etc down to 14th shakes 1 hand. Sum of 1 to 14 = 105.)
if there are 2 people in a room and each one shakes hands once with every other person in the room, how many hand shakes are there?... answer( 1 handshake) pretty easy isn't it? if there are 3 people in a room and everyone shakes hands with everyone else, how many hand shakes are there? answer( three handshakes) now how many handshakes will there be for 5 people in a room? its your time to shyne...
45 handshakes
4950
210
72
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.
there would be 26 handshakes if they were all done at once
