what do we understand by the term 'shadow zone'? Mention the shadow zone created by the P and S waves. |
Answer» tion: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. |
