(35 degree-wide belt named the P-wave shadow zone).Note what happens to the path of a P wave that just enters the outer liquid core.

The Earth has to have a molten, fluid core to explain the lack of S waves in the shadow zone, and the bending of P waves to form.This represents the area. that does not receive direct P-waves from an earthquake. 8.

Local frequency as a direct hydrocarbon indicator

No person or device has ever penetrated the crust to explore.Unlike the P-wave, the S-wave cannot travel through the molten outer core of the Earth, and this causes a shadow zone for S-waves opposite to where they originate.P-waves or S-waves are received in the shadow zone because (1). 27. How long did it take the P-wave to travel from.The shadow zone is the area of the earth from angular distances of 104 to 140 degrees from a given earthquake that does not receive any direct P waves.
