87: 31: 79: 66:, if the sediment is preserved in the rock record. In most cases, the environments associated with particular rock types or associations of rock types can be matched to existing analogues. However, the further back in geological time sediments were deposited, the more likely that direct modern analogues are not available (e.g. 148: – Rise and fall of the sea level under astronomical gravitational influences – processes due to tidal currents, creates tidal flats (fine-grained, ripple marks, cross-beds). Common sediments are silt and clay 164: – Area of loose particles at the edge of the sea or other body of water. Caused by waves and longshore currents. Creates beaches, spits, and sandbars with the common sediments of gravel and sand. 209: – Shoal of rock, coral, or other material lying beneath the surface of water caused by waves and tidal currents. Also creates adjacent basins. Common sediments are carbonates. 183:– processes due to waves and tidal currents, creates shelves and slopes, lagoons. Common sediments are carbonates (in tropical climates) or sand, silt, and clay (elsewhere) 154: – Shallow body of water separated from a larger one by a narrow landform. Little transportation, creates lagoon bottom environment. Common sediments are 268: 477: 107:– type of Fluvial deposit. Caused by moving water in a fan shape (Alluvial Fan) and containing mostly impermeable and nonporous sediments well sorted. 203: – Flat area on the deep ocean floor (abyssal plains) caused by ocean currents. Common sediments are clay, carbonate mud, silica mud. 142: – Silt deposition landform at the mouth of a river (possible cross beds, ripple marks) Common sediments are sand, silt, and clay. 17: 369: 129: – Sediment deposited by a lake – processes due to moving water, mainly lakes. Common sediments are sand, silt, and clay. 82:
