(5)Complete sentences by crossing out wrong answers.
1-rivers near their source flow down gentle/STEEP slopes creating V-/u- shaped valleys. 2-Nearer the mouth the gradient is GENTLE/steep creating v-/U- shaped valleys. 3-the river channel near the mouth is WIDER/narrower & DEEPER/shallower..FASTER/s
1. Waterfalls are often formed where a layer of harder rock overlays a layer of softer rock. 2. As the river passes over the softer rock, it is able to erode it at a faster rate, forming a step in the river bed.

(8)Formation of waterfalls(p2)
3.Forces of hydraulic action causes further erosion which makes the plunge pool & notch bigger overtime.4.As the notch grows,there isn't enough support under the hard rock & it collapse the plunge pool.

5.This adds rocks & boulders to the plunge pool,& the process of corrasion with hydraulic action further erodes plunge pool & notch.5.As it retreats,it leaves behind a steep sided gorge.
