Lunar Landscape

Posted by Wickedpinto on August 17, 2010

What causes the boulders to be freed up and to roll around in the regolith?   There is no atmosphere, or vulcanism that we know of.  Is it just the tidal forces of the earth? Was there an impact that upset the crust?  The picture looks pretty cool Though.  also those boulders look remarkably round.

Other than being a cool picture, it’s also kinda fascinating.  What is the source of erosion? are they all ejecta from impacts? or celestial objects that remained whole?  And why are they moving and rolling, what looks to be a significant distance in the weak gravity of the moon.
