- Step by step process of stratification
- Process of weathering: Rain, wind, water and plants began breaking down the igneous rock into smaller rock
- Process of erosion: Sediments are moved by wind, water and ice into low-lying areas
- This is the explanation of how sediment rock was formed.
- Deposition of sediments
- Eroded sediments end up in water and begin to settle(Sedimentation)
- Compaction
- Then, it gets moved to different places on the Earth's surface such as oceans, seas, dams, lakes and rivers.
- Cementation of the sediment to form rock
- Most sedimentary rocks form in water, where the weight of the water presses down on the sediment and form layers of sedimentary rock(Compaction)
- The sediment layers continue to form, with new layers forming on top of old layers. Sedimentary rocks continue to from all the time
- Compaction and heat help form the sedimentary rock. Earth's geothermal energy helps create heat to form glue rock with salt crystals found in the sediment that glue the layers together.
