How Tsunamis Work: The Science Behind the Waves?

A tsunami is like when a big wave starts because something shakes up the ocean, just like when you splash in a puddle and make ripples.

Imagine the ocean as a giant bathtub. When an earthquake happens underwater, it’s like someone bumped the side of the tub really hard. That bump sends out waves that travel across the whole bath, or even all the way around the world!

How the Wave Travels

Tsunamis can be super fast, faster than a running cheetah! They might not look big when they start, but as they get closer to the shore, they grow taller, like a sneeze that turns into a huge laugh.

What Happens When It Reaches Shore

When the wave gets to land, it's like a giant wall of water crashing in, maybe even flooding the streets! That’s why people near the ocean need to know about tsunamis so they can run to safety when one comes.
