Tsunami
Tsunamis are huge volumes of moving water that become monstrous waves when they hit the coast. What causes them and how do they grow to be so dangerous? Earth Science - Geology - Learning Points. Tsunamis are massive volumes of moving water. Landslides, volcanic eruptions and meteorites can create tsunamis - but they are most commonly caused by undersea earthquakes. Displacement of water above fault lines creates ripples which race across the ocean at the speed of a jet plane. As tsunamis reach shallow water, faster-moving water catches the front wave, createing a wall of water. A Twig Context Film. Reinforce and extend the learning required by the curriculum.
