Question

When a glacier moves, rocks and sediments in the bottom of the glacier scrape against the ground. This creates grooves known as

A. lateral moraines.
B. glacial till.
C. truncated spurs.
D. glacial striations

Answer 1

Answer: D. glacial striations

Step-by-step 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.

Answer 2

D. Glacial striations
