Location: Mid-Atlantic Ridge (Divergent Boundary)

The last place I visited on this tour is called the Mid-Atlantic Ridge, a divergent tectonic plate boundary located along the floor of the Atlantic Ocean. The longitude and latitude points are 0° 0'2.13"S  19°59'59.09"W. It separates the Eurasian Plate and the North American Plate in the North Atlantic and the African Plate from the South American Plate in the South Atlantic. A divergent boundary is a boundary between two lithospheric plates that are moving apart. Most divergent boundaries lie along the ocean floor like the Mid-Atlantic Ridge and have rift valleys, which are deep valleys at the center of the mid-ocean ridge. In a process called sea floor spreading, molten rock forces its way upward through cracks, or rifts along the valley. The molten rock cools, hardening into new oceanic crusts. The older oceanic crust on either side of the valley moves away from the mid-ocean ridge.
