Geology 103: Oceanography Quiz

Geology is a science that involves the history of the earth, and its life, mainly as recorded in rocks. Oceanography is studying the ocean's physical, chemical, and biological features, including the ocean's history. As far as this quiz goes, you will be accountable for knowing things like a giant, fast-moving ocean wave generated by an earthquake or submarine landslide. You definitely should take this excellent quiz.
