Tsunami waves are caused by earthquakes in the ocean floor. as the waves approach the shore, they usually grow in height. when this occurs, which aspect of the wave is changing? amplitude direction frequency speed wavelength

the answer would be a.) amplitude, because the height of the wave is changing

The correct answer is option A, Amplitude

Explanation:

The height of a wave depend on the energy per square meter and is given by the relationship as given below:

E∝H2

Energy of the wave depends on the amplitude of the wavelength. The greater the wavelength, the higher shall be the energy.  

For two waves of equal wavelengths, a wave with greater amplitude will release more energy than a wave of lesser amplitude and thus height of wave with greater amplitude will be high.

those characteristics are cellular organization, reproduction, metabolism, homeostasis, heredity, response to stimuli, growth and development, and adaptation through evolution. some things, such as a virus, demonstrate only a few of these characteristics and are, therefore, not alive
