1. Name and describe the layers of the Earth. How do these layers affect earthquake waves? How do earthquake waves help us to know what earth’s interior is like?

Crust, mantle and core are three layers of earth

Explanation:

The earth consists of three basic layers crust (uppermost), mental (middle layer), and the core as (bottom-most).  Due to the variation in the rates of energy that moves between the three layers i.e the earth waves knows as P, S, and L waves are known to occur at various points of time. These waves are called seismic waves and the P is called primary waves that can moves between the solids and liquids while the S layer moves to form solid objects and L long waves move.  All these moves through various velocities and on reaching the earth's surface tell about the depth, magnitude, and intensity which helps the earth scientists to determine the interior.

The correct answer should be brand c.
