  1. Lauren Winner The Mid-Atlantic Ridge http://www.cliffshade.com/colorado/images/mid_atlantic.gif

  2. The longest mountain range in the world, the Mid-Atlantic Ridge, runs right down the middle of the Atlantic ocean. It's the giant letter "C" between South America and Africa. Where is it? http://geomaps.wr.usgs.gov/parks/pltec/noaaMidAtlanticRidgeSM.jpg

  3. What is it? Submarine ridge lying along the floor of the central Atlantic Ocean. It is a long mountain chain running about 10,000 miles in a general but curving north-south direction from the Arctic Ocean to the southern tip of Africa. What began as a small crack in the Earth's crust is now the Mid-Atlantic Ridge, a giant undersea mountain range. As magma rises to escape along this ridge new crust is formed, sea-floors spread, and continents drift around the globe. http://www.daviddarling.info/images/mid-ocean_ridge_diagram.jpg
