Question

A mountain with pointed summits which rises from the sea floor but does not reach the surface of the ocean is called:

• A. submarine canyons
• B. seamount
• C. atoll
• D. guyots

Hint:

Seamounts are underwater volcanoes with pointed peaks that remain submerged below sea level.

Answer 1

The Correct Option is B

A mountain with pointed summits that rises from the sea floor but does not reach the surface of the ocean is called a "seamount". Here's why:

• Seamount: These are essentially underwater mountains formed by volcanic activity. They do not break through the ocean's surface, which distinguishes them from islands. Over time, some seamounts may reach above sea level, forming islands, but typically they remain submerged.
• Submarine canyons: These are deep, steep-sided valleys cut into the seabed of the continental slope, not rising structures.
• Atoll: An atoll is a ring-shaped coral reef, island, or series of islets, circling a lagoon. It is situated above sea level.
• Guyots: These are seamounts with flat tops. Unlike typical seamounts, guyots have been eroded by wave action, which is why they feature flattened summits.

Hence, the correct term for an underwater mountain that rises but does not reach the ocean surface is a "seamount".
