The life cycle of a river helps explain how it acts as an agent of erosion.. It should be obvious that the force of running water will create erosion in the first place. Running water will physically move objects and “carve” or erode rock formations if the motion and volume of water is continual. In the “youth” stage of river cycle, a river does just this: It carves out a path to it’s final destination over rock formations, wearing away the land as it does so. . Objectives. Learn basic concepts of sediment transport and fluvial geomorphology. Understand sediment budgets (sources, sinks, pathways for sediment). Discuss infrastructure and ecosystem response. 1.

A stream carves a channel through soil rock by removing a few small particles of rock at a time. The stream water slows down when it enters a pond, allowing the rock particles to settle at the bottom of the pond. Pressure combines these particles into a solid rock. What is the new rock called?.
