Select the correct answer.
Disturbances inside Earth’s core cause earthquakes. The starting point of the disturbance is called the epicenter. Why does the amplitude of a seismic wave usually decrease as the wave moves away from the epicenter?
A) The waves lose energy in the form of heat.
B) The frequency of the waves continues to increase.
C) The wavelength of the waves continues to decrease.
D) The waves encounter entirely different mediums.

Respuesta :

When a wave travels through a material, it loses a small amount of energy as heat. Eventually, the wave will stop when it loses all of its energy.

I think the answer is A.

The amplitude of a seismic wave usually decrease as the wave moves away from the epicenter because  the waves lose energy in the form of heat. The correct option is A.

What is an Amplitude of wave?

It is the maximum distance from the mean position of the wave.

The amplitude of the seismic waves continues to decrease with distance because waves keeps on spreading in the larger portion of area and dissipates heat.

Therefore, the amplitude of a seismic wave usually decreases when the wave moves away from the epicenter because the waves lose energy in the form of heat.  The correct option is A.
