The three types of seismic waves produced by an earthquake are primary, secondary, and
a. atmospheric.
b. surface.
c. elastic.
d. sedimentary.

The answer is B. There are three sorts of seismic waves. These are grouped on the premise of their entrance in the world's surface and their entry to seismographs. To begin with are essential waves, which arrive first and enter the most profound. At that point are the auxiliary waves, which enter less and touch base after essential waves. At long last are the surface waves, which don't infiltrate the world's surface and arrive the most recent.

B. Surface waves. During an earthquake, seismic waves are transmitted along different layers of the earth. These waves are caused when rocks break within the crust of the earth. The two major types of waves that are produced are body waves (which are further categorized into primary and secondary waves & they travel within the inner earth's layers) and surface waves (which move along the surface of the earth).
