 MARINE BIOLOGY EXAM #1 STUDY GUIDE 


Identify 4 major ocean basins?



Oceanography 

1. Identify 4 major ocean Basins?

2. How do the major ocean basins compare in size & depth?

3. Describe Earth’s surface:

5. Difference between continental crust & oceanic crust:

6. Identify the different boundaries and what happens to each of the boundaries: 7. What is created at mid­ocean ridges & what type of plate boundaries are they? 8. What are hypothermal vents? 

9. How do hypothermal vents & chimneys form?

12. What is the cause of magnetic stripe patterns on the seafloor?


How do the major ocean basins compare in size & depth?



13. How do magnetic stripes show evidence of seafloor spreading?

14. Explain the geological provinces: continental shelf, continental slope, continental rise,  deep ocean basin, etc.

15. Differences between active and passive margins?

16. What happens at each margin (active & passive)? We also discuss several other topics like What technique uses an injection?

17. What features define each kind of margin?

18. How do hotspots create island chains?

Properties of Seawater 

1. Describe the structure of water molecule:

2. What is hydrogen bonding? Don't forget about the age old question of What kind of effects does paying salaries have on the current period?

3. Describe the following properties and their importance:

• Boiling Point/ freezing point:

• Specific Heat Capacity: Don't forget about the age old question of Thomas jefferson had hypocritical views of human rights, but supported what?

• Heat of Vaporization:


What is the lithosphere & asthenosphere?



• Dissolving Power:

• Transparency:

• Pressure:

4. Why do we see a latitudinal gradient of sea surface temperature?

5. Where is the warmest & the coldest surface water?

6. What is salinity & how is it measured?

7. What unit describes salinity?

8. What is the salinity range for the open ocean?

9. What is the rule of constant proportions?

10. How is salinity increased or decreased?

11. What is the main cause of salinity changes in the ocean­ is it changes in amount of solute  or change in the amount of water?

12. Identify 2 factors that have greatest influence on seawater density:

13. How does each factor influence density (how can you increase/decrease)?

 MARINE BIOLOGY EXAM #1 STUDY GUIDE 

14. What are thermoclines & how are they formed?

15. What are pycnoclines & how are they formed?

16. How does the formation of thermoclines affect the mixing & exchange of materials  between layers of water above and below the thermocline? Don't forget about the age old question of How does the hydrophobic effect work?

17. What are seasonal thermoclines & why do they form ONLY seasonally? 18. Which regions are seasonal thermoclines found?

19. Do gasses dissolve better in warm or cold water?

20. Is oxygen soluble in seawater?

21. How does oxygen enter the ocean and how is it removed?

22. How do levels of oxygen vary by depth?

23. Why is carbon dioxide more soluble than oxygen in seawater?

24. How are nutrients like nitrates & phosphates distributed in the water column… are there  more near the surface or deeper?

25. What is POM?

26. What is DOM?

27. Identify the 2 factors of light loss in the water column?

28. Which colors are absorbed near the surface?

29. Which colors of light penetrate more deeply?
