How can tsunamis shape the Earth?

Answer 1

Tsunamis are such rare events that they have little effect on the shaping of land. Most are small and cause very little damage.

The extremely rare events like the 2004 Sumatra-Andaman earthquake and resulting tsunami at first sight cause devastating damage. There is a high cost in lives and many buildings and businesses collapse so it all looks terrible. In terms of shaping though the effects are almost inconsequential.

Collapsed buildings are removed. Areas are rebuilt. The shoreline suffers very little in the way of changing it's shape. A few years of weathering and the return of normal life erases virtually every trace it ever happened.

The effects of only a few years of natural weather - sun, wind and rain have far more effect and it causes lasting changes.

Answer 2

when tsunamis strike they erode things and change them quikly instead of the gradual prosess of erosion happening over thousands of years erosion is the prosess in which water or a natural force wears away rock or such

Answer 3

tsunamis cause erosion (wearing down of the land), it cause also kill many inhabitants of the land leaving no one to tend it, or huge slabs and land could be swallowed up by the ocean (tee hee the last one i made up, it never actually occured, but hey you never know)

water also loosens up the soil on the land causing mud slides and such.

Answer 4

the giant wave washes away the land and relocates it
