    Question

    Which landscape feature is typically formed during a

    river's middle course?
    A Waterfalls Correct Answer Incorrect Answer
    B A delta Correct Answer Incorrect Answer
    C V-shaped valley Correct Answer Incorrect Answer
    D A meander Correct Answer Incorrect Answer

    Solution

    In the middle course of a river, the gradient becomes less steep, and the river begins to erode laterally rather than vertically. This lateral erosion creates meanders—distinctive bends and curves in the river's path. As the water flows more slowly in the middle course, the river widens and forms these characteristic winding patterns. In contrast, waterfalls and V-shaped valleys typically form in the upper course where the gradient is steep and vertical erosion dominates, while deltas form at the river mouth where it meets a larger body of water like an ocean or lake.
