How Does Volcanoes & Earthquakes: How Tectonic Plates Shape Our Planet Work?

The Earth is like a giant puzzle made of big, moving pieces called tectonic plates, and when they move, they cause volcanoes and earthquakes.

Imagine your toy box is full of different blocks. Each block is a tectonic plate, and the floor beneath them is like the Earth’s inside, hot and squishy. When you shake the toy box, the blocks bump into each other or slide past one another. That's what happens when tectonic plates move.

• If two plates push together, it can make mountains or cause a volcano to erupt, like when you press your hands together and a ball of playdough pops out.
• If they slide past each other, the ground can shake suddenly, just like when you pull your blanket quickly and everything on top moves too. That's an earthquake.

Sometimes, these big moving pieces make loud noises or even create new land, like islands popping up in the ocean, it’s all part of how our planet is always changing, like a giant, slow-moving puzzle!
