GEOLOGY

Detailed explanation-1: -Mid-ocean ridges are part of chain of mountains some 84, 000 km long. The Mid-Atlantic Ridge is the longest mountain chain on Earth. These ridges are spreading centers or divergent plate boundaries where the upwelling of magma from the mantle creates new ocean floor.

Detailed explanation-2: -The mid ocean ridge systems are the largest geological features on the planet. The Mid-Atlantic Ridge (MAR) is a mostly underwater mountain range in the Atlantic Ocean that runs from 87°N-about 333km south of the North Pole-to subantarctic Bourvet island at 54°S.

Detailed explanation-3: -The mid-ocean ridge is a continuous range of undersea volcanic mountains that encircles the globe almost entirely underwater.

Detailed explanation-4: -The mid-ocean ridge is the longest mountain range on Earth. Spanning 40, 389 miles around the globe, it’s truly a global landmark. About 90 percent of the mid-ocean ridge system is under the ocean. This system of mountains and valleys criss-crosses the globe, resembling the stitches in a baseball.

Detailed explanation-5: -A mid-ocean ridge (or mid-oceanic ridge) is an underwater mountain range, typically having a valley known as a rift running along its axis, formed by plate tectonics. This type of oceanic ridge is characteristic of what is known as an oceanic spreading center.
