Sedimentary Rock
Formation:
• Layers of sediment are deposited at the bottom of
bodies of water.
• The layers get compacted from the pressure of the
layers above.
• As the water is squeezed out, the salts present in
the layers of sediment begin to crystallize.
• These salts help act as glue to hold the particles
together.
Sedimentary Rock
Identification:
• Layers of sediment, easily scraped, and
often crumble easily
• Sedimentary rock often contains fossils
