What Causes a ‘Tsunami’ and How Is It Different from a ‘Wave’?

A tsunami is like a giant wave caused by something big happening under the sea, like an earthquake or a volcano. Regular waves are smaller and come from wind, but tsunamis can be super fast and really strong when they reach the shore.

Imagine you're in a pool and someone jumps in, ripples spread out. A tsunami is like that, but on a much bigger scale. It starts with a big shake under the ocean, which pushes water up suddenly. This creates a wave that travels across the sea until it hits land, sometimes causing huge damage.
