Need Help Asap How do islands form

Explanation:

An island is formed when magma builds up and breaks the ocean's surface. In some cases, like the island of Hawaii, land masses merge together. ... For many volcanoes, formation can take thousands of years, though some volcanic islands can sometimes appear quite suddenly
