Question

What can you infer about the composition of Earth’s surface from the activity? ​

Answer 1

Answer:

Much of what we know about the world beneath our feet comes from seismic studies. Seismic studies give us indirect evidence of the composition of the layers of the Earth by studying how waves of energy produced by earthquakes travel through the Earth. These energy waves are called seismic waves.
