5. How are the mid-ocean ridges related to sea floor spreading?
a. Mid ocean ridges form because of the magma that comes to the
surface during sea floor spreading.
6. How is new crust formed at the mid-ocean ridges?
a. Magma comes to the surface and is cooled by sea water. This process
continues, pushing the plates in opposite directions.
7. What are the two pieces of evidence to prove sea floor spreading AFTER
Wegener’s time?
a. Sea floor spreading
b. Moving magnetic strips on the plates
8. Where are the oldest layers of rock found?
a. At the bottom
9. What is an index fossil?
a. A fossil used to determine the approximate time period a layer of rock
