All of these factors could contribute to the stream carving into the landscape. A drop in base level, such as sea level, would result in a steeper gradient for the stream to flow down and erode the landscape more quickly. Uplift of the land relative to the sea would also increase the stream's erosion potential. A change in climate could lead to more intense weathering and weakened rocks, making them more susceptible to erosion by the stream.
