Here are three playful ways to say it:
- A tsunami is a giant ocean wave that races to the shore after the seafloor gives a big shake — like a water superhero zooming to the beach!
- When the ground under the sea does a big wiggle, a huge wave jumps up and sprints toward the sand — that’s a tsunami!
- Imagine the ocean sneezing after the floor under it shakes — the big rush of water that rushes to the beach is a tsunami!
