The document discusses how various landforms created by rivers are formed: 1) V-shaped valleys form as the river cuts downward like a saw in the upper parts of the river, making the valley deeper. Rain erodes the edges, widening the top of the valley. 2) Waterfalls form where hard rock meets soft rock - the river cuts through the soft rock quickly, forming a cliff of hard rock above with the waterfall. 3) Students are challenged to draw a diagram within 3 minutes to explain how waterfalls form based on information provided in the text.

1. Landforms created by rivers LO To know how v-shaped valleys and, waterfalls form. Key words: Spurs, source, v-shaped valley, waterfall, gorge

2. Starter: Write down 3 facts that you learned last lesson Now compare your 3 facts with your friends Now write down what you think is the best fact that you learned last lesson is. Be prepared to be asked what you think this fact is.

3. Look closely at this photo; write in your books what you think it is. (River, hidden by rocks) It’s a V shaped valley. Did you get it?

4. Forming a V shaped Valley The river cuts downwards like a saw. This happens in the upper part of the river and makes the valley go deep. Rain erodes the edges to make it wider at the top. Vertical erosion is dominant

5. Make a neat copy of the diagram in your books – you only have 8 minutes so be quick. Interlocking spurs and a V-Shaped valley

6. What is this? How is it formed?

13. What have you just seen? How do you think it is formed?

14. So how do waterfalls form? Whole class spider diagram on board Ideas

15. Quick explanation Hopetoun Falls, Australia.

16. 60 second challenge!!! Look at the diagram. Your task is to remember as much as you can, because you will be tested on it very soon. (You can make rough notes in your book if you want)

18. Now comes the real test!!! Can you draw a large diagram of your own to explain how waterfalls form? Be accurate, neat and quick – you ONLY have 3 minutes to do this task.

19. The 3 minutes are up. Have you remembered how a waterfall forms? Hold your work up nice and high for everyone to see!!
