Identify the type of plate boundary shown in this picture. Explain how this type of boundary provides evidence that Earth's magnetic poles have reversed.

These are divergent boundaries! The magnetic poles being reversed can be proved but how the mountain range is now being pulled out. On convergent boundaries can create a mountain range by land colliding. Therefore, since the land is moving away from the center, it has created a divergent boundary on a set of mountains.

The correct answer is kettles.
