Question

These Islands are Volcanic islands created by subduction or a hotspot. They often have a volcanic cone at the center with ridges and valleys radiating outward (often each valley was under a single chief). Most of Melanesia consists o high islands because it is along the Pacific Ring of Fire. Hawaii is a high island on a geologic hotspot.

Answer 1

The islands described in the question are high islands, which are volcanic in origin and mountainous with high elevations. Melanesia consists mostly of high islands, while Hawaii is a high island on a geologic hotspot.

Step-by-step explanation:

The islands described in the question are high islands, which are volcanic in origin and mountainous with high elevations. They are often created by subduction or a hotspot, and typically have a volcanic cone at the center with ridges and valleys radiating outward.

Melanesia, a region that includes Papua New Guinea to Fiji, consists mostly of high islands due to its location along the Pacific Ring of Fire. Hawaii, on the other hand, is a high island located on a geologic hotspot.
