How are mid atlantic ridges formed
WebThe Mid-Atlantic Ridge is the longest mountain chain on Earth. It runs along the Atlantic Ocean floor from North America to beyond the southern tip of Africa. It rises 6,000–13,000ft (2,000–4,000m) above the sea floor, and runs for 10,000 miles (16,000km). Beneath the ridge is a place of great volcanic activity. Where the volcanoes have ...
