C and D are the right answer. I hope this helps (please give me brainliest)
D. The waves encounter entirely different mediums.
<h3>Why does the amplitude of a seismic wave decrease as the wave moves away from the epicenter?</h3>
At farther distances, the amplitude of the seismic waves decreases as the energy released by the earthquake spreads throughout a larger volume and different mediums of Earth.
So we can conclude that option D is the right answer.
