Sandstone is generally more resistant to erosion than shale due to its higher hardness and better ability to withstand weathering and fracturing. As a result, it is more likely to form steep cliffs or overhangs, which can create the necessary conditions for waterfalls to form. While shale can also form cliffs, it is typically more prone to erosion and tends to weather more easily, which can lead to a smoother or more sloping terrain.
