Question

Outline the progression of hot spot related seamount formation.

a) A volcanic island forms over a hot spot.
b) The movement of the tectonic plate carries the volcano away from the hot-spot source, causing it to go extinct.
c) As the island ages, it cools and subsides.
d) The island erodes until it is no longer emergent, and it becomes an underwater seamount.

Answer 1

Hot spot related seamount formation involves the formation of a volcanic island over a hot spot, followed by its movement away from the hot-spot source, cooling and subsiding, until it becomes an underwater seamount.

Step-by-step explanation:

The progression of hot spot related seamount formation involves several steps:

1. A volcanic island forms over a hot spot.
2. The movement of the tectonic plate carries the volcano away from the hot-spot source, causing it to go extinct.
3. As the island ages, it cools and subsides.
4. The island erodes until it is no longer emergent, and it becomes an underwater seamount.
