... The Mid-Atlantic ridge is part of an interconnected ocean ridge system that is the largest topographic feature on Earth’s surface, more than 70,000 km (43,000 miles) in length. This ocean ridge system winds through all the oceans something like the seam on a basketball. The ridges are from 3,000 to ...

Plate Tectonics
... In a divergent plate boundary, molten rock rises to the surface and cools to become new crust. This newly formed crust is continually being replaced by new molten rock. Older crust diverges and is forced to move away from the area where new molten rock will form into new crust. ...

Plate Tectonics Power Point
... Ocean-floor spreading helps to explain how continents drift. As a piece of the ocean floor moves, it takes its continent (if it has one) with it. Individual sections of midocean ridges are straight but the ridges as a whole curve.This is because the straight sections are offset by thin cracks known ...
