    EXPLANATION:

    • STATEMENT 2 IS INCORRECT. As the Tsunami approaches the coast wave shoaling effect takes place which increases amplitude (height) of the wave enormously.
    • The deeper the water; the faster the tsunami.
    • In the deep ocean tsunamis can move as fast as a jet plane over 500 mph and can cross entire oceans in less than a day. As the waves enter shallow water near land they slow to the speed of a car approximately 20 or 30 mph.
