Answer to Question 1

By understanding the geologic history of a region, geologists can predict whether it will be a
worthwhile place to search for petroleum or ore deposits.

Answer to Question 2

When a material is heated, it expands. Its density decreases, so it rises. After having risen some
distance, it begins to cool, contract, and become denser. Thus, the material sinks and returns to the
original level, where it will eventually be heated and rise again.
