SEDIMENTARY ROCKS
• Sedimentary Rock – Rocks formed from
sediment that is compacted and cemented
• Stratification – the process in which
sedimentary rocks are arranged in layers
• Strata – layers of rock
• Clastic Sedimentary Rock – rock made of
fragments of rocks cemented together
• Chemical Sedimentary Rock – rock that
forms from solutions of dissolved minerals
and water
• Organic Sedimentary Rock – rocks that
form from the remains of organisms that
were once living
Types of Sedimentary Rocks
Limestone:
•Made of calcium carbonate or calcite. The most
common sources are the shells of marine organisms.
•These type of rocks can be found in ancient sea beds.
Types of Sedimentary Rocks
Conglomerate:
•Made of rounded pebbles cemented
together. These pebbles have been
rounded by the action of moving
water.
•These can be found near rivers,
streams, or long ago beaches.
Types of Sedimentary Rocks
Coal:
•Made of fossilized peat or dead plant
material
•Found at the bottom of ancient swamps
Types of Sedimentary Rocks
Sandstone:
•Made from sediment formed from weathering of rock
into sand grains that are then cemented together into
solid stone over time
•Found in areas where ancient seafloors, dunes,
deserts, or beaches once occurred
