Answer to Question 1

ANS: B
Well-sorted sediments are those composed of mostly one size of particle and are common in the deep
ocean. Sorting is a function of the energy in an environment. Well-sorted sediments are found in areas
with limited energy. Poorly formed sediments are found in areas where there is a lot of energy in the
form of waves, tides, and currents. Information can be found in the section Sediments May Be
Classified by Particle Size.

Answer to Question 2

ANS: C
Diatomaceous earth has many uses to humans. It is mined for use in flat paints, pool filters, and
polishes to name a few. Information can be found in the section Pelagic Sediments Vary in
Composition and Thickness
