=====
Oddly, abrasion isn’t included in the many definitions of ablation. Abrasion is removal of material, as sandpaper removes wood fibers from a rough plank. That doesn’t seem much different from wind-carried sand ablating rock formations like the ones in Garden of the Gods in Colorado Springs, Colorado.
There must be some technical difference, I suppose.
