What type of glacier forms in a mountainous area?

• Alpine

• continental

• till

• moraine

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.
