Answer to Question 1

ANS: D
The geologists use sound waves because it reflects off these structures in particular signatures. These
distinctive signatures give them an idea where to drill. This is very useful because the cost of drilling
in the ocean is quite expensive. Information can be found in the section Physical Resources.
