A tsunami happens when something really big moves a lot of water. Like when an earthquake under the sea suddenly shifts the ground, and that pushes up a huge wave. It starts small in the ocean but grows bigger as it gets closer to land, just like how waves get taller near the shore.
Examples
- A big earthquake under the ocean pushes up the sea and makes a wave that hits the beach.
- Like when you jump into a pool, it creates ripples that spread out across the water.
- A landslide on the seashore sends waves rolling toward the city.
