All of the given options can cause a stream to begin carving into the landscape. If the base level is lowered, the stream will have more energy to flow downhill and cut into the landscape. If the land is uplifted relative to the sea, streams will begin to flow more quickly and develop a steeper slope to cut into the landscape. Finally, if a change in climate causes weathering and weakening of rocks, the stream will be able to more easily carve through the landscape.
