What causes tsunamis, and why are they so destructive? What will be an ideal response?
Many tsunamis are caused by the displacement of ocean water caused by crustal movement or
slumping as the result of faulting. They are very destructive because they are incredibly fast-moving
waves with long wavelengths. These waves reach large sizes only where they enter water shallow
enough for them to touch bottom (1/2 wave length), and thus the wave amplitude increases.
