Section 6.3Sedimentary Rock
Please write down the information that is in BLUE
Formation of Sedimentary Rock
Sedimentary rocks are formed by
weathering and erosion of other rock. Over
time that rock is deposited in new locations.
Those sediments are compacted and
cemented together.
3 types of sedimentary rock
1. Clastic rock
2. Chemical rock
3. Organic rock
Clastic rock
Rock that is formed from fragments of other
rock
Examples:
Sand and Gravel – Conglomerate
Sand – Sandstone
Silt and Clay – Shale
Quartz Conglomerate
Sandstone
Shale
Chemical rock
Dissolved minerals precipitate out of watersolutions and harden.Examples:Water evaporating – rock salt, gypsum, and
limestone
Minerals fall out of solution into the bottomof the ocean – limestone
Limestone
Organic rock
Sedimentary rock that consists plant and
animal remains.
Examples:
Limestone, coal, coral, and shell fragments
that have been glued together.
Coquina
Coral
Coal
Stratification
The layering of different sedimentary rock
types over time.
Minerals are usually deposited in low spots.
Over time the surrounding rock is weathered
away leaving the sedimentary rock behind.
Grand Canyon
Badlands
Fossils
The remains, impressions, or other evidence
of plant and animal life.
Examples:
The bones of an animal, leaf imprint, animal
tracks, and even fossilized fecal matter.
T Rex
Leaf
Ammonite
Mosquito
Amphibian Tracks
Dinosaur eggs
Fossil Poop
Ripple marks and Mud cracks
Ripple marks
patterns caused by the action of wind, water, and ocean currents
Mud cracks
When fossilized matter is left behind when mud dries and hardens into shale.

Nodules, Concretions, and Geodes
Nodules – lumps of fine grained silicate matter.
Concretions – round solid masses of calcium carbonate.
Geodes – hollowed out spheres containing crystallized limestone on the inside.
