Question
Write short notes on the following :
6. Mid Atlantic Ridge.
Solution
Mid Atlantic Ridge : The most striking feature of the Atlantic ocean is the presence of the mid-Atlantic Ridge. It extends from the north to the south parallel to the ‘S’ shape of the ocean itself. It divides the Atlantic Ocean into two deeper basins on either side. The
ridge is about 14,000 km long and about 1500 metres high. The ridge has stretched features. The slopes on both sides are very gentle throughout the greater part of its length. It rises as a series of steps and becomes rugged near the crest.
The ridge, though under the sea level, has many peaks projected out of the deep water above the surface of the ocean. These peaks are in fact, the islands of the Mid-Atlantic. Examples include Pico Island of Azores and Cape Verde Islands. Bermuda is a coral island. Ascension, Tristanda Cunha, St. Helena and Gough are volcanic islands.
