Mauna Kea is unusually topographically prominent for its height, with a wet prominence fifteenth in the world among mountains, and a dry prominence second in the world, after only Mount Everest. It is the highest peak on its island, so its wet prominence matches its height above sea level, at 4,207.3 m (13,803 ft).
The bases of mountain islands are below sea level, and given this consideration Mauna Kea (4,207 m (13,802 ft) above sea level) is the world's tallest mountain and volcano, rising about 10,203 m (33,474 ft) from the Pacific Ocean floor.
Several other mountains are sometimes claimed to be the "tallest mountains on Earth". Mauna Kea in Hawaii is tallest when measured from its base; [note 4] it rises over 10,200 m (33,464.6 ft) from its base on the mid-ocean floor, but only attains 4,205 m (13,796 ft) above sea level.
The highest and lowest points in China constitute the greatest elevation range within any single country at 9,002 metres (29,534 ft). The elevation ranges are also great in Nepal 8,789 metres (28,835 ft), Pakistan 8,611 metres (28,251 ft), and India 8,588 metres (28,176 ft). Monaco 's elevation range is among the greatest relative to surface ...
Topography of Oceania.

The Mid-Atlantic Ridge is a mid-ocean ridge (a divergent or constructive plate boundary) located along the floor of the Atlantic Ocean, and part of the longest mountain range in the world. In the North Atlantic, the ridge separates the North American from the Eurasian Plate and the African Plate, north and south of the Azores Triple Junction.
Undersea mountain range. Undersea mountain ranges are mountain ranges that are mostly or entirely underwater, and specifically under the surface of an ocean. If originated from current tectonic forces, they are often referred to as a mid-ocean ridge. In contrast, if formed by past above-water volcanism, they are known as a seamount chain.
Davidson Seamount is a seamount ( underwater volcano) located off the coast of Central California, 80 mi (129 km) southwest of Monterey and 75 mi (121 km) west of San Simeon. At 26 mi (42 km) long and 8 mi (13 km) wide, it is one of the largest known seamounts in the world. [4] From base to crest, the seamount is 7,480 ft (2,280 m) tall, yet ...
