The photograph shows scratched and grooved
bedrock with boulders on its surface. The scratches and grooves were most likely created when
alternating thawing and freezing of water cracked the bedrock
flooding from a nearby lake covered the bedrock
a glacier dragged rocks over the bedrock
rocks from a landslide slid along the bedrock
- 21. Multiple Choice
Base your answer to the following question on the map. Arrows on the map show the location and orientation of glacial striations on the surface bedrock. Dark shading shows the location of large moraines (glacial deposits). How were the striations made?
Frost action cracked the bedrock during the ice age.
Rocks at the bottom of the glaciers were dragged over the bedrock.
Particles carried by winds scratched the bedrock during the ice age.
Particles carried by glacial meltwater eroded the bedrock.

The glacier will decrease in size, and the ice front will advance.
The glacier will increase in size, and the ice front will retreat.
The glacier will increase in size, and the ice front will advance.
