Yes, Antigua is not a volcanic island. It is a low-lying island formed mainly from limestone and coral reefs. There are no active volcanoes on the island.
Hawaii is a volcanic island, formed by volcanic activity millions of years ago. It is part of a volcanic island chain in the Pacific Ocean.
Montserrat is a volcanic island because it was formed by the rising magma from the Earth's mantle through a weak spot in the Earth's crust, leading to the accumulation of layers of volcanic rock over time. This volcanic activity has resulted in the island's rugged topography and the presence of volcanic features such as lava domes and pyroclastic flows.
Fiji is primarily a volcanic island. It is part of the Ring of Fire and was formed through volcanic activity. However, there are also some coral atolls in Fiji, particularly in the Lau Group of islands.
Ocean trenches, volcanic arcs, and island arcs are examples of geologic features on the ocean floor formed by crustal plates moving together. Subduction zones are common in these areas, where one plate is forced beneath another, creating deep ocean trenches and leading to volcanic activity along the plate boundaries. Island arcs can also form as a result of subduction, with chains of volcanic islands aligning parallel to the trenches.

Volcanic islands are formed by volcanoes and are therefore composed of volcanic rock.

The island in Crater, called Wizard Island was formed by small volcanic eruptions that occurred after the Crater Lake caldera formed but before the volcano went extinct.
Yes, Hispaniola island was formed by volcanic activity in the past, but it is not currently an active volcanic area. The island is located in the Caribbean and is shared by the countries of Haiti and the Dominican Republic.
When it was formed by the movement of tectonic plates as a volcanic island.
