Here are three playful ways to say it for a 7-year-old:
- Ocean sneeze: A tsunami is like a huge ocean sneeze — when the ground under the sea wiggles, the water whooshes toward the beach super fast.
- Sea jump: Imagine the sea taking a giant jump: when the ocean floor shivers, a fast, tall wave runs all the way to the shore.
- Water train: A tsunami is a giant water train that zooms to the beach after the seafloor rumbles; it rushes really fast and carries lots of water.
