What are real world examples of divergent plate boundaries?
The mid-Atlantic ridge that is slowly pushing North America away from Europe.
The mid-Atlantic ridge lies mostly in the middle of the Atlantic Ocean and is the classic example of a divergent plate boundary. This tells us that a couple of large mantel plumes are at work below the Earth's surface and these are gradually pulling the crust apart.
It is where the ancient content of Pangea used to be, prior to being torn apart by this divergent zone. The mid-Atlantic ridge is visible on the surface on the Earth at Iceland and is a famous geological place to visit.
