Answer to Question 1

ANS: F
Siliceous oozes actually take much longer to dissolve into seawater than calcareous oozes. These two
types have different organisms that break down in seawater at different rates. Information can be found
in the section Pelagic Sediments Vary in Composition and Thickness.



Answer to Question 2

ANS: T
The process that compresses the biological particles into fecal pellets allows sediments that would
normally need 20 to 50 years to sink to the bottom in as little as two weeks. Information can be found
in the section Pelagic Sediments Vary in Composition and Thickness
