Answer 2

Geologists study direct evidence of the earth's interior by (b) measuring seismic wave activity.

• The earth's interior is made up of a number of layers such as the crust, mantle, outer and inner cores.
• It is when earthquakes occur, the geologists try to record the seismic waves that are produced in these earthquakes which gives them a clear picture of the earth's interior.
• Each layer of the earth surrounds the one beneath it and this property of the earth's interior is very popularily compared to an onion.
