3. Sedimentary Rocks Parent rocks undergo weathering Parent rocks undergo weathering Weathering produces loose material Weathering produces loose material Loose material is Eroded (transported) Loose material is Eroded (transported) Sediment (transported material) is modified by sorting and rounding Sediment (transported material) is modified by sorting and rounding Sediment is deposited in layers Sediment is deposited in layers Layers of additional sediment bury sediments Layers of additional sediment bury sediments Ions dissolved in groundwater form crystals that glue the sediment grains together (Cementation) Ions dissolved in groundwater form crystals that glue the sediment grains together (Cementation)
