Mckay · Answer 1

D. Glacial striations

Explanation:

Glacial striations are marks and grooves carved on a rock surface as the materials carried by it abraded the surfaces of the earth.

Raquel Ortega · Answer 2

Answer: D. glacial striations

Explanation:

Glaciers striations are the features formed over the bedrock due to glacier erosion. This occurs due to glacier abrasion that happens during glacier erosion or retreating glacier. This results in the formation of striations into multiple straight parallel lines and scrape marks over the bedrock or ground. These striations appear as grooves.
