Morphology

seamount = sea + mount (transparent) = sea + mount

A straightforward compound of 'sea' + 'mount' whose meaning (a mountain in the sea) follows directly from its parts.

Etymology

Seamount comes from the two parts sea and mount, where mount means 'mountain' or 'to rise', so a seamount is literally a mountain that rises from the ocean floor but does not reach the water's surface.
