Why is it in Iceland, is the only place where the mid ocean ridge is above sea level?

What has caused it to be able to be seen above sea level there? I am confused by this and have been looking it up all night and day. Please in layman terms please.


That I understand but why is it above seal level is what I am asking, what caused it to raise up? I read the page you cited but I dont see the answer as to how and why this happened in there.

    because if it weren't there would be no Iceland. There are other smaller islands atop the Ridge.

    The islands, from north to south, with their respective highest peaks and location, are:

    Northern Hemisphere (North Atlantic Ridge):

    1. Jan Mayen (Beerenberg, 2277 m (at 71° 06' N, 08° 12' W), in the Arctic Ocean

    2. Iceland (Hvannadalshnúkur in the Vatnajökull, 2109.6 m (at 64° 01' N, 16° 41' W), through which the ridge runs

    3. Azores (Ponta do Pico or Pico Alto, on Pico Island, 2351 m, (at 38°28′0″N 28°24′0″W / 38.466667°N 28.4°W / 38.466667; -28.4)

    4. Bermuda (Town Hill, on Main Island, 76 m (at 32° 18′ N, 64° 47′ W) (Bermuda was formed on the ridge, but is now considerably west of it)

    5. Saint Peter and Paul Rocks (Southwest Rock, 22.5 m, at 00°55′08″N 29°20′35″W / 0.91889°N 29.34306°W / 0.91889; -29.34306)

    Southern Hemisphere (South Atlantic Ridge):

    1. Ascension Island (The Peak, Green Mountain, 859 m, at 7° 59' S, 14° 25' W)

    2. Tristan da Cunha (Queen Mary's Peak, 2062 m, at 37° 05' S, 12° 17' W)

    3. Gough Island (Edinburgh Peak, 909 m, at 40° 20' S, 10° 00' W)

    4. Bouvet Island (Olavtoppen, 780 m, at 54° 24' S, 03° 21' E)
