Answer to Question 1

ANS: B
The erosion would produce many sizes of sediments. Poorly sorted sediments form in environments
where energy fluctuates especially due to wave and current actions. Information can be found in the
section Sediments May Be Classified by Particle Size.



Answer to Question 2

ANS: C
Diatom oozes occur at high latitudes in areas with seasonal upwelling. Although diatom and
radiolarian oozes are both siliceous, radiolarian ooze tends to form in equatorial waters. Information
can be found in the section Pelagic Sediments Vary in Composition and Thickness.
