Sedimentary Rock

1
Sedimentary Rock

• The rocks that form the Earths surface are
  broken down and washed away by mechanical and
  chemical weathering and erosion.
• But rocks are formed when the sediment is
  eventually deposited (deposition) and then
  squeezed (compacted) and cemented together
  (cementation).
• These rocks are called Sedimentary Rock.

Sedimentary Rock

• This deposition, compaction and cementation is
  called lithification.
