Answer to Question 1

ANS: D
There are large ranges of sizes in sediments. Most marine sediments are comprised of finer particles
like clay, silt, and sand. These particles are easily transported throughout the ocean. Information can be
found in the section Sediments May Be Classified by Particle Size.

Answer to Question 2

ANS: C
There were two main factors in the creation of paleoceanography. Stratigraphy and the advent of deep
sea drilling allowed scientists to interpret changes in ocean and atmospheric circulations. Information
can be found in the section Sediments Are Historical Records of Ocean Processes.
