Explanation;
-Striations are scratches formed on a rock surface by rock fragments frozen into the bottom of a moving glacier.Rocks embedded in the bottom of the glacier scrape along the newly exposed bedrock and leave behind line-shaped scratch marks called glacial striations. The direction of the scratch marks tells us the direction that the glacier flowed
