Question

1. what can the reader infer about the diagram at the bottom of page 2?

a. the diagram represents light waves moving through the ground.
b. the diagram represents sound waves moving through the ground.
c. the diagram represents seismic waves moving through the ground.
d. the diagram represents echolocation.

Explanation:

The question references seismic waves at the top, so the diagram on page 2 is tied to this topic. Seismic waves travel through the ground, while light waves do not move through ground effectively, sound waves here are not the focus (seismic is the specified wave type), and echolocation is for sound reflection, not ground-penetrating seismic waves.

Answer:

C. The diagram represents seismic waves moving through the ground.
