2. Describe how hot spots can form new islands
3. How do we belive atolls are formed?
4. How do particle size affect how fast sediments settle on the sea floor?
5. Can you design an experiment that could help us show how fast sediments settle?
6. On page 101 there is a figure of the Hjulstrøm diagram. Explain it in your own words?
7. How are the different forms of biogenous sediments formed?
