Question

Why don't S shock waves get recorded on seismographs all over the globe after an earthquake?

A. S shock waves fade out as they travel through the earth.
B. All shock waves overlap so much that S waves can't be seen on the seismograph
C. S waves travel in the opposite direction, so they are never recorded.
D. S waves are stopped by the outer core of the earth.

Answer 1

A. S shock waves fade out as they travel through the earth.

Step-by-step explanation:

Seismic waves lose a great number of their energy when they travel over long distances so after an earthquake, they are not recorded on the seismograph.

S waves don't get recorded on seismographs all over the globe after an earthquake because they fade out as they travel through the earth.
