Detailed explanation-2: -A seamount is an underwater mountain formed by volcanic activity.
Detailed explanation-3: -If a volcano does not reach the surface of the ocean, it is called a seamount. If a volcano grows in height and volume enough to reach the ocean’s surface, it becomes a volcanic island (like the islands of Hawaii).
