Mid Atlantic Ridge

The Mid Atlantic Ridge is a huge chain of underwater mountains that runs down the middle of the Atlantic Ocean. The chain runs from Bouvet island near the North Pole 6,200 miles to just below South Africa.

Divergent boundary

The Mid-Atlantic Ridge is a divergent boundary where crustal plates are separating. How magma oozing up from the mantle flows into a rift valley between the two plates forming the mountain range. The mountain range is part of the mid ocean ridge that is approximately 25,000 miles long.

Mountain range at Mid-Atlantic Ridge

The mountain range is between 300 and 600 miles wide. It rises above the seafloor an average of two miles. Several peaks form islands on the ridge. Most of the islands are uninhabited.

Iceland sits on the ridge

Iceland volcanoes are part of the Mid-Atlantic Ridge above a hot spot. Scientists are constantly studying the volcanoes. They can study how a divergent boundary forms the Mid-Atlantic Ridge on land without having to go to the bottom of the ocean floor with a submersible to view the ridge formation in action.
