Evidence to support the fact that Earth's central core is solid can be attributed to
 
  A) a decrease in S-wave velocity as they encounter and move through the inner core.
  B) an increase in P-wave velocity as they encounter and move through the inner core.
  C) a decrease in P-wave velocity as they encounter and move through the inner core.
  D) an increase in S-wave velocity as they encounter and move through the inner core.

Question 2

The primary evidence that the outer core is molten is an abrupt
 
  A) increase in the velocity of P-waves, but no increase in S-waves.
  B) increase in the velocity of L-waves.
  C) stop of S-wave propagation, and a decrease in P-wave velocity.
  D) stop of P-wave propagation, and a decrease in S-wave velocity.
