crust
What are the three types of plate boundaries?
convergent, divergent, and transform boundaries
Why is finding a fossil of the same land-dwelling animal (that could not swim) on two different continents, like South America and Africa, considered strong evidence for continental drift?
It shows that the continents must have been connected at one time (aka Pangea and continental drift)

Fossils of the same freshwater reptile, Mesosaurus, were found in both South America and Africa. This discovery is strong evidence that supports this major theory about what supercontinent?
Pangea
Why is the oldest rock on the ocean floor located far away from mid-ocean ridges?
new rock forms at the ridge and pushes the older rock away
