Answer to Question 1

ANS: D
Carbon dioxide is able to form different compositions when dissolved in water. First, it creates
carbonic acid, a weak acid. The acid then disassociates into bicarbonate and carbonate. Information
can be found in the section The Ocean's Acid-Base Balance Varies with Dissolved Components and
Depth.

Answer to Question 2

ANS: B
The mixing time of the ocean is due to vigorous current activity. This activity allows constituent
materials to become evenly distributed throughout the ocean. Information can be found in the section
Seawater Consists of Water and Dissolved Solids.
