For question 13 the answer should be in the lower stretch of a river as there is a higher kinetic energy.

Question 13 has the wrong answer, it should be in the lower stretch of the river, because there is the least potential energy to erode downwards, as the lower course isn't that high above base level but the most kinetic energy to erode outwards. Question 8 is also really oddly worded. Apart from that this is a good quiz, thanks :)
