c-their size, shape and density.
19-currents can sort particles of rocks and sand :
a-when rocks erode slowly.
b-when rocks erode quickly.
20-there is a relationship between the average grain size and the
strength of the bottom currents at the time that sediment is deposited :
a- true.
b-false.
21-fine grained sediments denote : a-low energy environment.
b-high energy environment.
22-coarse sediments denote : a- low energy environments.
b-high energy environments.
23-on the basis of water depth :
a-the ocean can be subdivided into two major areas of sedimentation.
b-the ocean can be subdivided into three major areas of
sedimentation.
24-grain size varies systematically with water depth : a- true.
b-false.
25-shallow water consists of : a- coarse sediments.
b-fine sediments.
26-deep water contain : a- coarse sediments.
b-fine sediments.
27-carbonate shelves : a- are found away from rivers , where calcium
carbonate can accumulate.
b-are found near rivers , where calcium carbonate is abundant.
28- carbonate shelves : a- are found in the poles.
