Are undersea mountain ranges called seamounts?

Answer 1

No, individual mountains underwater are called seamounts, but although the ranges are underwater, they are still referred to as mountain ranges, or oceanic ridges.

The largest and longest mountain range on earth is formed from mid-ocean ridges and stretches 70,000 kilometers around the planet.

Answer 2

Pl. read the different definitions:
1.An underwater mountain rising from the ocean floor and having a peaked or flat-topped summit below the surface of the sea.
2.Large submarine volcanic mountain rising at least 3,000 ft (1,000 m) above the surrounding seafloor; smaller submarine volcanoes are called sea knolls, and flat-topped seamounts are called guyots. Seamounts are abundant and occur in all major ocean basins. By the late 1970s more than 10,000 seamounts had been reported in the Pacific Ocean basin alone. Virtually every oceanographic expedition discovers new seamounts, and it is estimated that about 20,000 exist worldwide.
3.an underwater mountain rising above the ocean floor.
4.A seamount is a mountain rising from the ocean seafloor that does not reach to the water's surface (sea level), and thus is not an island. These are typically formed from extinct volcanos, that rise abruptly and are usually found rising from a seafloor of 1,000 4,000 metres depth. They are defined by oceanographers as independent features that rise to at least 1,000 metres above the seafloor. The peaks are often found hundreds to thousands of metres below the surface, and are therefore considered to be within the deep sea. An estimated 30,000 seamounts occur across the globe, with only a few having been studied.

(Seamounts are often found in groupings or submerged archipelagos, a classic example being the Emperor Seamounts, which are an extension of the Hawaiian Islands, which were formed millions of years ago by volcanism, and have since subsided to below sea level. The long chain of islands and seamounts, extending thousands of kilometres northwest from the Big Island demonstrates the movement of a plate over a volcanic hotspot.

Isolated seamounts and those without clear volcanic origins appear to be less common. In recent years, geologists have confirmed that a number of seamounts are active undersea volcanoes: Lo‘ihi in the Hawaiian Islands and Vailu‘ulu‘u in the Manu‘a Group (Samoa) are examples.)

Answer 3

No, the undersea mountain range (there is only one) is called the Mid-oceanic Ridge, and it is the largest and longest mountain chain on the planet.

true. a seamount is a mountain rising from the ocean seafloor that does not reach to the water's surface (sea level), and thus is not an island. These are typically formed from extinct volcanoes, that rise abruptly and are usually found rising from a seafloor of 1,000–4,000 metres depth

Answer 6

Ranges are not sea mounts, only individual sea mountains are called sea mounts because sea mountain sounds like a oxymoron.
