Which sign may appear on rock surfaces due to glacial abrasion?
Answer and explanation
Correct answer: Long striations
The governing concept is abrasion by moving ice. Rock fragments frozen into the base of a glacier act like tools and scrape the underlying bedrock as the ice moves. This produces long, often parallel grooves or striations that may indicate the direction of glacial movement. Therefore option B is correct. Deltas and coastal bars are depositional features made mainly by water, while crescent sand dunes are shaped by wind.
