How Does a Volcano Erupt Under the Sea?

Imagine you're in a bathtub filled with water, and you pour hot soup into it. The soup pushes the water up, just like underwater volcanoes erupt when molten rock pushes seawater upward. Volcanoes under the sea are like this: when magma from deep inside Earth rises and breaks through the ocean floor, it pushes the seawater up, creating a powerful eruption that can form new islands or even mountains.
