Two hundred and twenty-five million years ago, all of today's continents were part of a single continent known as Pangaea. The map below shows the positions of some of these continents. There is a significant amount of evidence that can be used to support the theory that Pangaea existed. Which of the following explains how the map shows evidence for the existence of Pangaea?

same fossils.
The continents' shapes do not fit together very well, and each continent has completely
different fossils.
The continents' shapes fit together well, and some continents have the same fossils.
The continents' shapes fit together well, but each continent has completely different
fossils.
The diagram below shows some activity at a mid-ocean ridge.
Which of the following best describes the process shown in the diagram?
Solid rock liquefies as it reaches the surface and flows outward.
