Sedimentary rocks


  • Sedimentary rocks are formed because of the pressure as particles of sediment are deposited out of water as it flows carrying the particles in suspension.
  • As sediment deposition builds up, the pressure squeezes the sediment into layered solids.
  • This process is known as lithification.
  • The term diagenesis is used to describe all the chemical and physical changes.
  • Sedimentary rocks are laid down in layers called strata. This process is known as stratification.
