The Arctic Ocean has a D- shaped form with an average depth of 3,500m and an area equal to 1/12 of the Pacific Ocean. The Arctic Ocean is mostly frozen and a 15 feet permanent thick ice is found due to which there are difficulties of sounding the bottom.

The Indian ocean is the only ocean named after a country. It is smaller than Pacific and Atlantic Ocean in areal extent. It has Asia in the north, Africa in the west, Asia in the east, Australia in the south east and Antarctica in the south. The Indian subcontinent in the north divided Indian Ocean into Arabian Sea and Bay of Bengal.The average depth of the ocean is 4,000 meters. Major part of the coastal lands of Indian Ocean formed by the block mountain of Gondoanaland are compact and solid. 

Mid -Atlantic is a submerged mountain range, representing the zone of divergent or constructive plate margins. It is S shaped extends for 14,450 km from Iceland in the north and the Bouvet Iceland in the south. The ridge is known as Dolphin Rise to the north and Challenger Rise to the south of equator. It is known as Wyville Thompson Ridge between Iceland and Scotland. The ridge becomes quite extensive to the south of Greenland and Iceland and called Telegraphic Plateau.
