The Formation of Sedimentary Rocks

November2

Wind and water erodes and deposits sediments

Sediments fall to the bottom of oceans and lakes

Sediments areĀ  pressed and squeezed together through a process called compaction

Over millions of years, layers continue to build-up

The sediments become stuck together forming the rocks that eventually become layered

The layers become cemented due to extreme pressure and heat

Heat and pressure changes or transforms the compressed sediments into sedimentary rock
