What is the name of the waves given off by an earthquake?
A
Seismic waves
B
Radiation waves
C
Sound waves
D
Compaction waves
Explanation: 

Detailed explanation-1: -There are two different types wave produced by an earthquake: body waves and surface waves. Body waves are seismic waves that travel through the body of the earth. Body waves are reflected and transmitted at interfaces where seismic velocity and/or density change, and they obey Snell’s law.

Detailed explanation-2: -Types of Seismic Waves The two main types of waves are body waves and surface waves. Body waves can travel through the Earth’s inner layers, but surface waves can only move along the surface of the planet like ripples on water. Earthquakes send out seismic energy as both body and surface waves.

Detailed explanation-3: -When an earthquake occurs, it releases energy waves, known as Seismic waves. It is like the ripples created in water if you throw a stone in it. Seismic waves are like ripples that can travel through the inside of the earth and on the surface.

Detailed explanation-4: -There are three major kinds of seismic waves: P, S, and surface waves. P and S waves together are sometimes called body waves because they can travel through the body of the earth, and are not trapped near the surface.

Detailed explanation-5: -The seismic waves travel inside the Earth in four different types which are P-waves, S-waves, Rayleigh waves and Love waves. P-waves (primary) and S-waves (secondary) are body waves which are the fastest waves and can travel inside and surface of the Earth.
