Here are the solutions to Question 7.4: 7.4.1 The type of river at A is a consequent river. It flows in the direction of the general slope of the land. 7.4.2 The human-made feature at B is a pass (likely a mountain pass or a winding road). Its purpose is to provide a route for transportation (e.g., a road or trail) through the mountainous terrain, connecting areas on either side of the steep slope. 7.4.3 Drainage pattern C: Radial pattern Drainage pattern D: Dendritic pattern 7.4.4 Drainage pattern C (Radial): This pattern develops on a dome-shaped structure or an isolated conical hill/mountain. The streams flow outwards in all directions from a central high point, following the steepest gradient. Drainage pattern D (Dendritic): This pattern develops on homogeneous rock (rock with uniform resistance to erosion) or unconsolidated sediments. The topography typically has a gentle, uniform slope, allowing streams to branch out in a tree-like fashion without strong structural control. 7.4.5 The location of the Blyderivierspoort Dam is ideal for several reasons: It is situated in a narrow gorge or poort, which means a shorter and less expensive dam wall is required to block the river. The steep valley sides provide a strong and stable foundation for the dam wall and efficiently contain a large volume of water. The dam is located downstream of a large catchment area (the Blyde River Canyon), ensuring a reliable and sufficient supply of water to fill the reservoir. The presence of a canyon suggests the underlying rock is hard and resistant, providing a stable geological base for the dam structure and minimizing seepage. 3 done, 2 left today.
