Explain the difference between a river system and a tributary. (25R) 16. Describe the factors that affect how fast the rate of erosion is (erosive energy) of a river. (26R) 16. Describe the factors that affect how fast the rate of erosion is (erosive energy) of a river. (26R) 17. Describe a river with a lot of erosive energy. Where is it located? What does it carry? What does it look like? Then describe a river with much less erosive energy. (26R) 17. Describe a river with a lot of erosive energy. Where is it located? What does it carry? What does it look like?
