Dear students. The work for today is:
Make a detailed drawing of the ocean floor, marking as many of the elements as you can. Send it to me by skoleplan or E-mail.
Answer the following questions, as detailed as you can, and send them to me in an E -mail or with skoleplan:
- Define the difference between divergent and convergent boundaries, and how the different type of boundaries affect the arcitecture of the sea floor.
- Describe how hot spots can form new islands
- How do we belive atolls are formed?
- How do particle size affect how fast sediments settle on the sea floor?
- Can you design an experiment that could help us show how fast sediments settle?
- On page 101 there is a figure of the Hjulstrøm diagram. Explain it in your own words?
- How are the different forms of biogenous sediments formed?
- Why are coastal marine sediments richer in terrigenous sediments than deep ocean sediments?
Homework for next week:
