Now, I don't know HOW to read that picture of fish scales, but it seems to me a gravitational pull 2/3 less than ours couldn't cause that erosion ... but what do I know ... I drive a truck.
It won’t do it as fast as on earth, but the process is the same.
Funny you should say that. I've had several good friends who were truckers, and every one of them had above average I.Q.s and educations. Some of those guys were scary brilliant.
One in particular used to post about advanced physics to a biker forum I belonged to. Most of the time, he seemed like any other Joe, but when he got started on scientific topics, he held the floor.
You're in good company, bud.
