19. Running Water I: Rivers, Erosion and Deposition Rivers are the most common land feature on Earth and play a vital role in the sculpting of land. This program shows landscapes formed by rivers, the various types of rivers, the basic parts of a river, and how characteristics of rivers — their slope, channel, and discharge — erode and build the surrounding terrain. Aspects of flooding are also discussed. Episode 19: Running Water -
Erosion and Deposition
Describe the hydrologic Cycle. What is sheet erosion? What 3 things do all streams do? What is one important factor in how rivers shape the land? What is a divide? What factors can cause a river's velocity to increase? What is discharge? What are the 3 erosional processes of rivers? What is the stream Load? What factors affect sediment transport? What are river bars? Describe a river that has meanders. How does an oxbow form? Describe a braided river. How often do most streams flood? What is a floodplain, and what does a river store there? What is a levee? How do streams work to maintain equilibrium? How is a delta different from an alluvial fan? What happens at "Red Eye Crossing" when water levels fluctuate? What geologic factors contribute to the evolution of river systems? |
