What are volcano chains?

Volcano chains are like long lines of volcanoes that pop up one after another, kind of like a row of cookies in a bakery.

Imagine you have a big pile of playdough, and every time you press your finger into it, a little hill pops up. If you keep pressing your finger along the same path, you’ll make a line of hills, just like volcanoes forming a chain.

Think about a plate in the Earth’s crust moving slowly, kind of like a conveyor belt. When it moves over a hot spot, which is like a melted lava lamp deep inside the Earth, volcanoes can pop up where the plate passes over the hot spot.

Each time the plate moves forward, a new volcano forms, making a long line, just like how you get a row of cookies when you press your finger along the playdough. That’s why we call them volcano chains!

Some famous examples are the Hawaiian Islands, where each island is a volcano that formed as the plate moved over the hot spot. It's like the Earth is baking a long row of cookies, one after another!
