Features of the upper-course of a river (F4 Video Project)

In the second term form 4 have been studying rivers, including the upper course features. The upper course is an area of vertical erosion caused by abrasion. There is little horizontal erosion.

As part of their effort to create case studies for their exams, form 4 created video projects of major features found in the upper course, namely waterfalls, V-shaped valleys and potholes.

These were marked by using a marking rubric. Out of 60, these three groups received marks of 44, 36 and 32. Can you match the scores to the videos?
