The map on the left shows the present locations of South America and Africa. Remains of the
Mesosaurus, an extinct freshwater reptile, have been found in similarly aged bedrock formed
from the lake sediments at locations X and Y.
____29. Which statement represents the most logical conclusion to draw from this evidence?
A. Mesosaurus migrated across the ocean from location X to location Y.
B. Mesosaurus came into existence on several widely separated continents.
C. The continents of South America and Africa were connected when the Mesosaurus lived.
D. The present climates at location X and Y are similar.
Base your answer/s to the following question/s on the diagram on the left,
which shows a cutaway view of Earth in which the interior layers are visible.
The paths of the earthquake/seismic waves generated at point X are also
shown. A, B, C, and D are locations of seismic stations on Earth’s surface,
and Point E is located in Earth’s interior.
____30. Both P and S waves were received at seismic stations A and B ,
but only P waves were received at seismic stations C and D. Which
statement best explains why this occurred?
A. S waves are much weaker than P waves.
B. S waves travel faster that P waves.
C. The liquid outer core prevents the S waves from travelling to seismic
stations C and D.
D. The solid outer core prevents the S waves from travelling to seismic
stations C and D.
____31. Location X is the ________
A. focus B. seismic station C. epicenter
D. seismic wave
____ 32. Directly ______ the focus is the epicenter.
A. below
B. above
____ 33. Seismic waves ________ as they travel inside Earth.
A. refracts (refraction)
b. reflects ( reflection)
____ 34. Since P- waves were detected on seismic stations C and D, you can conclude that _____.
A. P waves can only travel in liquids and not in solids.
B P waves can only travel in solids and not in liquids.
C. P waves can travel in solids and liquids.
D. P waves are faster that S waves.
