Is the shape and direction of a flow formed by weathering?

The shape and direction of a flow are not formed by weathering. Instead, the shape and direction of a flow are governed by various factors such as the nature of the topography, prevailing wind patterns, vegetation cover, soil characteristics, and human-made structures. However, weathering processes can alter the composition of the landscape, influencing the flow dynamics over time. Weathering, which generally involves chemical and physical breakdown of rocks and minerals at the Earth's surface, influences sediment yield and shape of the topography, which in turn can impact flow patterns. Nevertheless, direct control over the shape and direction of a flow is outside the scope of weathering processes.
