Can you answer these please!?

Question

1. what are the two states that have been hit by tsunamis the most?

2. what is the difference between a tidal wave nd a tsunami?

3. why are tsunamis called seismic waves?

4.why does the amplitude of the wave go up in shallow water?

5. where will the energy of the wave go when it hits shore?

Answer 1

1.  Alaska and Hawaii

2. We used to call tsunamis tidal waves even after it was learned that they are not caused by tides.  We adopted the Japanese word in order to make the distinction. I have heard, though, that the English translation of tsunami is "tidal wave".  Anyway, when you say tsunami today everyone knows your're talking about the siesmically produced wave.

3. Tsunamis are seismic waves propagating in water.

4.  The increasing amplitude of the wave in shallow water is a phenomenon called hydraulic jump.  Water is incompressible, so as the sea bottom rises the volume of the water causes the wave to rise even higher.

5.The energy of the wave is finally absorbed by collisions with objects on land and friction.

Answer 2

I am sure of all the following answer, but the first one.  So you might want to research the first question a bit more.

1. Alaska and California are my guesses.  Hawaii is also a possibility.  Eathquakes in the Pacific Ocean are commonplace and these can cause tsunamis any time.

2. A tidal wave is caused by the tides, which are the natural result of gravitational pull from the Sun and the Moon.  Tsunamis are caused by under ocean earthquakes.  When the ocean floor shifts, the ocean rises and falls creating the waves we call tsunamis.

3. Seismic is simply another name for earthquake.  Tsunamis are waves caused by earthquake; therefore, they are seismic waves.

4. As the water shallows, the bottom part of the waves encounter relsistance with the ocean bottom.  The top part of the waves do not.  Thus the top part of the following wave action catches up with the slower bottom parts of the waves closer in to shore.  In a real sense, the increased amplitude is due to the following waves piling up on the earlier waves close in to shore.

5. Energy is converted.  What the kinetic energy of a wave converts to depends on what that wave encounters.  But a lot of energy is converted to heat due to friction as the wave flow over land and buildings and such.  Eventually the kinetic energy is sapped and the wave recedes.  A lot of energy is transferred to solids as the wave crashes into buildings, trees, and such and in that transfer these things are crushed.  It's like the front end of a car that crumples when running into something.
