Study Guide Material (Stacey’s Guide) :

1) How does river salinity compare to sea water salinity?

2) Know the primary sources of salts.

3) Understand what is meant by the “salt balance.”

4) How are salts removed from the oceans to maintain the “salt balance?”

5) Which salts have the greatest “residence times” in the oceans?

6) What is meant by the “principles of constant proportion?”

7) Know the percentage of the primary gases (N₂, O₂, CO₂) in the atmosphere,

as compared to that in surface seawater and in the total oceans.

8) What is meant by the “saturation value” of a gas?

9) How does the “saturation value” change with temperature, salinity and pressure?
