First of all there are different kinds of sea mounts, in reference to your question it would have to be a volcanic sea mount to begin with. It would become a volcanic island by continuing to erupt until it broke the surface of the ocean. Some excellent examples of volcanic sea mounts that became volcanic islands are the Hawaiian Islands
By volcanoes under the sea that get bigger and bigger - and become islands..
Mountains on the ocean floor that rise above sea level and form volcanic islands are called seamounts. These seamounts are formed by volcanic activity and can eventually emerge from the water to become volcanic islands.
That's correct! Steep-sided islands, such as volcanic islands, can form from the gradual or abrupt emergence of seamounts due to volcanic activity on the ocean floor. As the seamount grows and breaches the ocean surface, it can eventually develop into an island with steep sides due to the accumulation of volcanic materials.

Many, they are called volcanic undersea mounts.

The Aleutian Islands.
Aleutian Islands
The Aleutian Islands.
They are volcanic in origin, conical in shape and at least 1000 metres above the ocean floor
Volcanic islands have black sand beaches whilst Limestone (coral) islands have white sand beaches.Volcanic islands have fertile soil and in Limestone islands' is not as fertile as Volcanic islands.Volcanic islands tend to be tall whilst Limestone tend to be flat.Volcanic islands have many sulphur springs whilst Limestone islands have little or no sulpher springs.Limestone islands are formed from 'Secretions'of the sea and Volcanic islands are formed from igneous rock and lava.THANK YOUHOPE YOU LEARNED FROM IT!
Due to volcanic eruptions forming islands along a weakness in a long line of the sea bed, the Hawaiian Island chains was formed.
