How is the deep interior of the earth mapped

ANSWER:

The study of the seismic waves and how these are bent, reflected, sped up or delayed in the various interior layers of the earth is used to map the interior layers of the earth and get information on them.

EXPLANATION:

The deep interior of the earth cannot be drilled in with holes to study about it. All 'layers of the earth' except the crust cannot be drilled into to study about them. Scientists study these deep interior layers of the earth by watching seismic waves that are caused by earthquakes.
