Answer to Question 1

ANS: T
The distribution of sediments is dependent upon currents and marine processes rather than on the
productivity. There are less terrigenous sediments in the pelagic areas due to their larger size.
Information can be found in the section Pelagic Sediments Vary in Composition and Thickness.

Answer to Question 2

ANS: T
Lithification occurs when neritic sediments are compacted into sedimentary rock. The process is often
induced by pressure or cementation. Information can be found in the section Neritic Sediments Overlie
Continental Margins.
