GEOL 1001 Lecture Notes - Lecture 7: Braided River, Dune, Weathering
Document Summary
Deposition: occurs when the wind/water/ice slows down and the sediments fall out of the method of transportation, could occur in lakes and rivers and deltas. If they don"t move far and don"t have anything to erode them they will stay angular: glacier. Can carry a rock of any size. Over time will wear the rock into smaller particles: stream. Wears the rocks down to rounded rocks: dunes. Deposits the fine particles around the same area and creates dunes: delta. Where river empties into a larger body of water. River looses velocity so it deposits the sediment in that location: lake. Coal is formed from the plant material. Just like dune environment but in a more arid place, only sand: reef. Like a small lake but along a beach: tidal flat. When tide is high the water is covering it but when tide is low it is exposed. Where sediment from the river is deposited into the oceans.
