Sedimentary Rocks Flashcards
solid
fragments or particles
that are transported
and deposited by
wind, water, or ice.
Sediment
solid rock
that is connected
continuously down
into Earth’s crust,
rather than existing
as separate pieces or
masses surrounded by
loose materials.
Bedrock
a rock, usually layered,
that results from
the consolidation
or lithification
of sediment, for
example a clastic rock,
such as sandstone, a
chemical rock, such
as rock salt, or an
organic rock, such as
coal.
Sedimentary Rock
layers
of rock, visually
separable from other
layers above and
below.
Strata
the reduction in bulk
volume or thickness
of fine-grained
sediments due to
increasing weight of
overlying material that
is continually being
deposited.
Compaction
the process by which
sediments are
converted into rock
by the precipitation
of a mineral “cement”
among the grains of
sediment.
Cementation
a sedimentary
rock made up mostly
of fragments derived
from preexisting
rocks and transported
mechanically to their
places of deposition.
Clastic Sedimentary Rock
an individual
fragment of sediment
produced by the
physical disintegration
of a larger rock mass.
Clast
the process of forming
solid mineral
constituents from
a solution by
evaporation.
Precipitation
a sedimentary
rock formed by direct
chemical precipitation
of minerals from a
solution.
Chemical Sedimentary Rock
a state
of physical balance.
Stability occurs when
opposing forces cancel
each other out.
Equilibrium
a sedimentary
rock consisting mainly
of the remains of
organisms.
Organic Sedimentary Rock
