SPRING 2008---INTRODUCTION TO OCEANOGRAPHY--- GEOL 107 Study Guide #5---Prof. W. Berelson Note: these guides are designed to help you decide what’s important to know from the lecture and book material. They may not cover every single topic I might ask about on an exam, but they cover most topics. To study for exams, use this guide, use notes from class, use textbook. -The hydrologic cycle is called a ‘cycle’ --- why? -How does water leave the ocean? -Draw a picture of the H 2 O molecule, label the + and – sides. -Why does light of different wavelengths penetrate the ocean to different depths? -What color light penetrates the ocean to the greatest depth? -Name 6 major ions dissolved in sea water? -Chemicals are added to the ocean, chemicals are removed from the ocean, this also constitutes a ‘cycle’, T or F? Name major mechanisms that add and remove chemicals to the ocean. -Define residence time. -What does it mean to say the ocean has a good capacity for pH buffering?
