why are p- waves received but S- waves are not received by seismic stations located on the opposite side of Earth from an earthquake epicenter?
a. S-waves travel slower than p - waves
b. S-waves travel faster than p-waves
c. earths inner core absorbs s-waves
d.earths outer core absorbs s-waves
Please help!!!!
Answer: D is the right answer
Explanation:
An S wave shadow is produced in the contrary direction of the earthquake because P waves can travel through all layers of the ground but S waves cannot due to the solid core.
What are body waves?Body waves from an earthquake arrive before their corresponding surface waves because they travel into the Earth's interior. More frequently occurring than surface waves are these waves.
The P wave, or main wave, is the initial type of body wave. It is the type of seismic wave that travels the fastest and arrives first at a seismic station. P waves can travel through both solid rock and fluids, such as water or the Earth's liquid layers.
Secondary waves, often known as S waves, are the second kind of body wave. Seismologists first believed that the outer core of the Earth is a liquid since S waves can only pass through solid objects. Rock particles are moved up and down or side to side by S waves, which are always parallel to the wave's direction of propagation.
