2
Sedimentary rock formation in which dissolved
minerals precipitate or new minerals grow between
the sediment grains.
3
Cementation
4
Depositional feature of sedimentary rock that
forms as inclined layers of sediment are carried
forward across a horizontal surface.
5
Cross bedding
6
Examples include breccia, sandstone, and shale
formed by lithification of clastic sediments.
7
Clastic sedimentary rock
8
Occurs when sediments are laid down on the ground
or sink to the bottom of a body of water.
9
Deposition
10
Horizontal layering in sedimentary rock that can
range from a millimeter thick to several meters
thick.
11
Bedding
12
Solid particles deposited on Earth's surface that
can form sedimentary rocks by processes such as
weathering, erosion, deposition, and
lithification.
13
Sediments
14
Chemical sedimentary rock that forms mainly in
restricted ocean basins in areas with high
evaporation rates.
15
Evaporite
16
Describes rock and mineral fragments produced by
weathering and erosion and classified according
to particle size and shape.
17
Clastic
18
Transformation of sediments into rock through
compaction and cementation
19
Lithification
20
Percentage of open spaces between grains in a
rock.
21
Porosity
22
Depositional feature of sedimentary rock in which
particles are progressively heavier and coarser
toward the bottom layers of bedding.
23
Graded bedding
