Mid-Atlantic Ridge

The Mid-Atlantic Ridge is a mid-ocean ridge located along the floor of the Atlantic Ocean, separating the North American, Eurasian, and African plates in the North Atlantic and the African and South American plates in the South Atlantic. The ridge is approximately 65,000 kilometers long and has an average spreading rate of 2.5 centimeters per year, with parts of it extending above sea level, such as in Iceland. The discovery of the ridge was made in the 19th century, but its significance and role in the breakup of the supercontinent Pangaea were not fully understood until the 1950s, when scientists mapped its bathymetry and discovered its connection to a worldwide system of mid-ocean ridges.learn more on wikipedia
