The Mid-Atlantic Ridge is a divergent (tectonic plates moving apart) boundary on the ocean floor. The Mid-Atlantic Ridge is a type of mid-ocean ridge that forms at these types of boundaries. This divergent boundary is between the South American plate and the African plate. This ridge stretches from the Arctic Ocean to the southern tip of Africa! That is very far, over 10,000 miles! The Mid-Atlantic Ridge is home to lots of mountains (also known as seamounts) and lots of volcanoes. This is because the sea floor is spreading which causes magma to seep up and solidfy to make new crust!
