How Do Volcanoes Shape Island Formation?

Volcanoes are like nature's lava factories. When molten rock from deep inside the Earth pushes up through cracks in the ocean floor, it can pile up until a new island forms. Think of it like building sandcastles, one layer at a time. Over thousands of years, this process creates islands such as Hawaii or Iceland.
