Which outcome occurs when glaciers pulverize bedrock upstream?

A)Loess deposits form downwind later
B)Oxbow lakes increase local biodiversity
C)Volcanic ash changes soil alkalinity
D)Sinkholes destabilize groundwater recharge

💡 Explanation

Loess deposits form due to glacial grinding producing fine silt (glacial flour) which is then transported by wind; therefore, downwind areas accumulate loess rather than the other options, because those involve different causes like meandering rivers or volcanic activity. This is aeolian deposition.
