Which of the following ocean relief features has pointed summits that rise from the seafloor but do not reach the ocean’s surface, often attaining heights of 3,000–4,500 metres?
Seamount
A seamount is a mountain with a pointed summit rising from the seafloor that does not reach the surface of the ocean. Seamounts are of volcanic origin and may be 3,000–4,500 metres tall; the Emperor Seamount in the Pacific is an example.
A guyot is a flat-topped seamount, its top levelled by erosion, so it does not have a pointed summit.
The continental shelf is the gently sloping, shallow extension of the continent, and a mid-oceanic ridge is a long chain of underwater mountains along plate boundaries, not a single peaked summit.
Hence, the answer is Seamount.
