Why Do Volcanoes Sometimes Erupt In Chains?

Sometimes, volcanoes erupt in a line, like when you knock over a row of dominoes. Imagine the Earth is like a big cake, and when it gets hot inside, it pushes up molten rock from deep below. This molten rock can cause several volcanoes to form right next to each other. When one volcano explodes, it might wake up its neighbors and cause them to erupt too, like a volcanic domino effect!
