The most well known would be the Hawaiian island mountain range caused by underwater volcanic activity.
Underwater.
The place exposed peaks of an underwater moutain range is the Carribean Sea.
Divergent bruh ;*
a range of underwater mountains and valleys is an
Mid Oceanianic Ridge
The longest mountain chain is the Mid-Oceanic Ridge, which runs under all 7 oceans and spans from around California to North of Greenland. It is estimated to be 49,700 miles long. The longest above seal level mountain range is the Andes Mountain Range, which runs down the west border of South America. It is estimated to be 4,300 miles long. The tallest mountain range is the Himalayas with 16 peaks above 26,000 ft, the highest of which is Mt. Everest at 29,035ft.

The Gotthard Base Tunnel goes under the Swiss Alps, specifically the Saint-Gotthard Massif, which is part of the Lepontine Alps. It is the longest and deepest railway tunnel in the world, passing through the heart of the Swiss mountain range.
The longest underwater mountain range is the Mid-Atlantic Ridge. It stretches for over 16,000 miles (25,000 kilometers) and bisects the Atlantic Ocean from the Arctic Ocean to the southern tip of Africa.
The Andes - over 4,000 miles! There are longer ones if you include mountain ranges under water...
A mountain range that is completely under water is a mid-ocean ridge.
The Pacific Rise is the mountain range under the Pacific Ocean. It parallels the coast of North and South America.
It is the thickest under mountains ranges.
