Answer to Question 1

ANS: B
Richard Oldham reasoned that a dense fluid within the Earth absorbed the S waves. He expanded his
theory to include the prediction of shadow zones where the S waves did not occur due to that dense
liquid. Information can be found in the section The Study of Earthquakes Provides Evidence of
Layering.



Answer to Question 2

ANS: C
The lithosphere includes continental and oceanic crust and the uppermost portion of the cool and rigid
mantle. The layer is 100 to 200 kilometers thick. Information can be found in the section Earth's Inner
Structure Was Gradually Revealed.
