IF YOU GET GOOD GRADES ON SCIENCE TEST HELP ME PLEASE!!!!
they know that tsunamis,or ocean waves with a very large wave amplitude, happens after anther event, such as an earthquake or landslide has dramatically shifted the earths crust and therefore the water above that crust.while difficult to see the amplitude and wavelength of the individual waves while they are far out at sea, we can see how large they are as they get into shallower areas as they approach the shoreline. based on the model and explanation, how does an earthquake cause tsunamis?
A. an earthquake seismic wave provides mechanical energy to the ocean. as energy is added the amplitude of the wave is increased.
B. as the earthquake vibrates more waves are created. more waves means that there is less space between them decreasing the wavelength. because amplitude is inversely related to wavelength, this that the waves must be less energetic.
C. as the earthquake creates more waves the frequency is increased. because amplitude is directly related to frequency, the amplitude is also increased.
D. an earthquake seismic waves overlap and build upon each other as the earth continues to shake. as the earth shakes more, the amplitude of the wave increases.
