* Sea mounts are volcanic in origin. They are formed by eruptions of magma from the Earth's mantle, which builds up over time to create a mountain on the ocean floor.

* They are located on the ocean floor. Sea mounts are underwater mountains, rising from the seabed.

* Not all sea mounts are located on the ocean floor. Some sea mounts can rise above sea level, forming islands. For example, the Hawaiian Islands are a chain of volcanic sea mounts.

So, while the statement "Sea mountains are volcanic located on the ocean floor" is accurate for many sea mounts, it's important to remember that some can rise above sea level.
