EARTHQUAKES
Lesson 1 - Page 4

There are other stresses on the lithosphere caused by the very fact that our Earth rotates on its axis. The equator moves much faster than the poles. Itís like when a basketball player can balance a spinning ball on its finger. The player has found the point of the axis that is not moving and balances it. As you go to the equator of Earth from the rotational axis you travel from 0 miles per hour to 1000 miles per hour. On Earth we donít feel it because of other physical constraints, but to an "Alien" looking down at us. Well, a polar bear on the North Pole and penguins on the South Pole would be standing still, while people in New York would be moving about 600 miles per hour, even if they were standing still in traffic. So what does this have to do with earthquakes?
