Explain how mountain rock can end up in a river delta.
Answer (3)
Mountain rock can end up in the delta of a river because the river delta is where sediment that flows from up river (potentially from a mountain) ends up before the river empties into an ocean or sea. Mountain rock can flow down river with other sediments and materials that are picked up along the way.
Mountain rock can end up in a river delta through erosion. Glaciers erode the surrounding rock and carry the rocks with them. When the glacier melts, the rocks are deposited in the river delta. ;
Mountain rocks reach river deltas through erosion by glaciers and rivers, followed by transportation and eventual deposition when the river flow slows down as it enters a larger body of water. This sediment accumulation forms the delta over time. Factors like the energy of the river and sediment size influence the delta's formation.
