Ever wondered what's the difference between a tsunami and a tidal wave? Both are powerful ocean phenomena, but they have distinct causes. Tidal waves are caused by the gravitational interaction between Earth and the moon, resulting in daily high and low tides. Tsunamis, on the other hand, are triggered by underwater earthquakes, landslides, volcanoes, or meteorites, which displace water and create massive waves.
