What is the term used to describe the distance between 100 and 140 degrees where p waves decrease in size and disappear

Sagot :

Answer:

shadow zone

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. The shadow zone results from S waves being stopped entirely by the liquid core and P waves being bent (refracted) by the liquid core.
