Volcanic islands and island chains, like the Hawaiian Islands were created by hot spots, which may or may not occur on a plate's boundary.
Explanation:
Volcanic island and island chains were created by hot spots. Hot spots resulted in the formation of Hawaiian islands. Hot Spots are areas where the magma rises upwards till it erupts from the seafloor. Hot spots can be found in the middle or on the sides of tectonic plates.
The areas where tectonic plates come together to form volcanoes. Hot spots in the middle of the Pacific Ocean resulted in the formation of Hawaiian Islands. The hot spots do not move but the plates move which is why volcanic areas can be found in different regions.
