Re: Rock erosion
Yes, lots of weathering.
I spent a good while searching the NASA photos for a lunar rock with a sharp edge - didn't find one. All edges, on top or underneath are rounded off - clear signs of weathering.
Apollo 16 and 17 have some great photos of this BTW. Astronauts even lent against them - no danger of a suit rip or a dust stain, even the photos of them collecting them for samples show lovely rounded edges.
They even had geologist Schmitt examine the weathering patterns - Apollo 17 IIRC. NASA says the dust is sharp but their photos show the rocks are smooth - maybe there is a connection?
