QUESTION 18 2.56 points Save A What is the P wave shadow zone? It is an area on the surface that absorbs P waves On a seismograph chart, it is the area after a large earthquake deflects the pen so much that the pen can not return to its base position to record subsequent vibrations. O It is an area on the surface of the Earth that does not receive direct P waves from an earthquake It is an area in which multiple reflections of P waves create numerous lines on a seismograph. These lines merge to make a large dark area on the chart.Explanation / Answer
18) it is an area on the surface of the earth that does not receive direct P waves from an earthquake
Shadow zone is the area of the earth 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 by the liquid core.
19) it is theorized that it is liquid based on temp, pressure, and the composition of the rocks in that area
