What is true about the formation of seamounts?

The formation of seamounts involves various geological processes, and the correct assertion highlights their potential to exist both submerged and above the water surface. Seamounts are typically formed by volcanic activity, where magma from the ocean floor builds up over time to create underwater mountains.

When tectonic forces push these volcanic formations above sea level, they can become islands. However, many seamounts remain completely submerged beneath the ocean's surface, making them noticeable only through sonar and other underwater surveying techniques. Therefore, seamounts can indeed exist in different states: either rising above the water or lying entirely beneath it, which is why this option accurately reflects their characteristics and formation processes.
