Question

Quizplus · Accepted Answer

The marks in the image are characteristic of abrasion, which is the process of glacial erosion that involves the scraping and scouring of the underlying rock surface by the abrasive action of the glacier's moving ice and debris. Plucking, quarrying, and jointing may also contribute to the overall erosion process, but they are not the dominant factors responsible for the marks in the image.
