Volcanoes happen at 2 out of 4 plate boundaries: Constructive plate boundaries and destructive plate boundaries.
In a constructive plate boundary, the plates move apart, causing earthquakes, and letting magma pass through, creating volcanoes.
In a destructive plate boundary, the plates push together. This creates a subduction zone. The rock jolts and grinds its way down causing earthquakes and volcanoes.

What are groups of volcanoes called?
If it is a single island, it is simply known as a volcanic island! If however it is a chain or string of separate islands then it may be a volcanic island arc (these form parallel to trenches at subduction zones) or a volcanic island chain (these form where a mantle plume creates a hotspot and may be in the centre of a tectonic plate. A good example would be the Hawaiian island chain). They can also form a cluster of islands (an archipelago) such as the Canary Islands (again formed by hotspot volcanism) in the Atlantic of the coast of Morocco.
What American islands are actually an underwater chain of volcanoes?
The American islands that are actually an underwater chain of volcanoes are the Hawaiian Islands. These islands were formed by volcanic activity from the Hawaiian-Emperor seamount chain. The islands of Hawaii, Maui, Oahu, Kauai, and others are all part of this volcanic chain.
Were there volcanoes in Haiti?
Haiti does not have active volcanoes. The most recent volcanic activity occurred on the neighboring island of Martinique, which is part of the Lesser Antilles volcanic arc. Haiti is situated on a different tectonic plate boundary, which does not have volcanic activity.
What would happen if volcanic eruptions continued to occur on the sea floor?
There are volcanoes along the floor of the ocean that form a trench. When these volcanoes erupt, it can cause tectonic movements.
How many volcanoes do the Bahamas have?
None. The Bahamas are not volcanic. They are reef islands.
Is a volcanic island transform?
No. Volcanoes do not form at transform boundaries. Volcanic islands can form at convergent boundaries and at hot spots.
Volcanoes can form on the ocean floor.?
They can and do. Many small rocky islands in the pacific are volcanic in origin.
Why did the Volcanic Marianas Islands form west of the Marianas Trench?
The Volcanic Marianas Islands form west of the Marianas trench because plates are formed by underwater volcanoes which will move gently to the west.

Do volcanoes form from barrier islands?
No. Volcanoes form either as a result of tectonic plates colliding or pulling apart, or from plumes of hot material in the mantle. Barrier islands are usually sedimentary features and are not related to volcanic activity.

How volcanic islands formed?
By volcanoes under the sea that get bigger and bigger - and become islands..
Why would you find a volcanic rock on a volcanic island?
Volcanic islands are formed by volcanoes and are therefore composed of volcanic rock.
How many volcanic islands does Hawaii have?
All of the Hawaiian Islands are volcanic, but only Hawaii, the Big Island, has active volcanoes at this time.
What is the definition of volcanic islands?
A Volcanic Island is an island that was made from volcanoes erupting from the ocean floor.
How many islands have volcanoes?
There are approximately 1500 active volcanoes in the world, and many of them are located on islands. It is estimated that there are hundreds of volcanic islands globally, but the exact number can vary as new volcanic activity can create or alter islands over time.
