How's this for a deep crater

in #science6 years ago (edited)

Takes quite a different collision to produce one of these.

And a unique set of underlying geology, this one is imposed on the wall of a much more ancient crater.

Nice find. That got me curious about what is known about lunar strata.

Our moon was molten internally in the past and was very active volcanically. The dark patches that make up the Man in the moon are actually massive solidified flood volcanics not too dissimilar from our very own flood basalts here on earth.

As far as the surface strata go; check out this post:

thank you for sharing this interest photo

Why are craters round? Do impactors only strike at right angles.
