As you saw in class today, we still believe that the earth is spreading apart. There is direct evidence of this happening through the evidence from rock cores, the magnetic polarity of the planet, as well as, sonar mapping of the sea floor.
The rest of the week will be focused on sea floor spreading and continental drift. Expect a test regarding these principals early next week.
HOMEWORK due Wednesday9/26/07.
