Sediments are composed of weathered rock, and sometime organic material, that is deposited. These deposits are then covered by more sediment or debris. WebA rock that contains beds is stratified or displays stratification. Strata form during sediment deposition, that is, the laying down of sediment. Meanwhile, if a change in current speed or sediment grain size occurs or perhaps the sediment supply is cut off, a bedding plane forms. Bedding planes are surfaces that separate one stratum from another.
