SEDIMENTARY ROCKS
w

sedimentary rock from a pre-existing rock.
w
Explain the terms weathering, erosion,
transport, deposition, compaction, cementation,
and lithification as they
apply to the formation of sedimentary rocks.
w
Differentiate between chemical sediments and
clastic (detrital) sediments.
w
List three kinds of clastic (detrital)
sediments, and four kinds of chemical sediments.
w
List and describe examples of mechanical
weathering and chemical weathering,
and describe the products of each.
w
List the major processes by which sediments are
transported.
w
Explain why sedimentary rocks often exhibit
layering, and why they may contain
fossils.
w
Describe the two most important processes by
which lithification occurs.
w
Using a mineral identification key, demonstrate
that you can recognize and describe the mineral
properties of hand samples of calcite, dolomite,
gypsum, halite, and quartz.
w
Using a rock key, demonstrate that you can
recognize, explain the formation of, and
describe the characteristics of hand samples of
