Wind

Erosion is a natural phenomena in which the surface or subsurface layers of the soil is removed and displaced to other locations by the action of an agent like water, air and others. In the given situation wind is the agent of erosion because it is already mentioned that it was a windy day, therefore, wind carried away the sediments from a hilltop to the ground at the bottom of the hill.

a time line cause it goes from 685 to 978

one would be wind another would be water density
