Which of the following features is found in the upper course of a river?
Answer Details
One feature that is found in the upper course of a river is a gorge. The upper course of a river is where it begins, typically in upland or mountainous areas, and is characterized by steep gradients, high energy, and narrow channels. Gorges are deep, narrow valleys with steep sides that are formed by the erosive power of the river as it cuts down into the landscape. They are a common feature in the upper course of a river where the water is moving quickly and eroding the surrounding rocks and soil. Levees, ox-bow lakes, and deltas are features that are typically found in the middle and lower courses of a river where the water is moving more slowly and has less erosive power.
