Photo 1 - from the Earth Science World Image Bank

Photo 2 - from the Earth Science World Image Bank

Photo 3 - a gallery of 11 photos showing erosion and weathering from National Geographic

Arrange the landforms due to erosion by size, from smallest erosion channel to largest. Which do you think might form in a very short time? Which do you think took the longest to form?
Hint: Use other objects in the picture to determine the size of the channels.
