Explanation:

A seamount is defined as an underwater (submerged) volcanic mountain, typically basaltic, that rises from the ocean floor but does not reach the water's surface. It is not limited to being extinct or active, nor does it have a flat top (that describes a guyot). The key trait is a submerged basaltic volcano over 1 km in height.

Answer:

a submerged basaltic volcano more than 1 km high
