select the correct answer.\nthe epicenter of an earthquake is located in a sandy desert region. seismic waves move outward from the epicenter. a rocky region is located a few hundred miles from the desert. the particles of matter are more closely packed in rock than they are in sand. which statement correctly describes the change in seismic waves as they move from sand to rock?\na. the waves change from transverse to longitudinal.\nb. the waves change from longitudinal to transverse.\nc. the waves speed up.\nd. the waves slow down.\ne. the wave speed is unchanged.

Answer

Brief Explanations:

Seismic wave speed depends on the medium's properties. In a medium where particles are more closely - packed like rock compared to sand, the wave speed increases. Seismic waves do not change from transverse to longitudinal or vice - versa just due to a change from sand to rock.

Answer:

C. The waves speed up.
