How Does [Why series] Earth Science Episode 2 - Volcanoes, Earthquakes Work?

Earth’s crust is like a puzzle made of big, moving pieces, and when those pieces shift or crash together, they cause volcanoes and earthquakes.

Imagine the Earth has a skin made up of huge plates, kind of like giant floor tiles in your living room. These plates are always slowly moving, sometimes just a little bit, like when you shift your feet while sitting on the couch.

When these plates move, they can push into each other or pull apart. If they crash together, it’s like two kids bumping into each other in a hallway, that bump can cause an earthquake, which feels like the floor is shaking under your feet.

When plates pull apart, it creates cracks deep inside the Earth. Melted rock, or lava, flows up through these cracks and erupts out of the ground, that’s a volcano! It's like when you open a soda bottle really fast: pressure builds up, and then whoosh, fizzy liquid sprays everywhere.

Sometimes, plates can also push together so hard that they melt into lava, which then flows out in a big eruption. That’s how mountains and volcanoes are born, just like how your blocks stack up when you build a tower!
