What does a glacial erratic indicate?
Answer and explanation
Correct answer: Transport of a different rock from far away by a glacier
A glacial erratic is an isolated boulder or rock fragment whose lithology differs from the bedrock beneath it. Glacial ice can pluck and carry such material over considerable distances before depositing it when the ice melts or retreats. Its presence therefore provides evidence of former glacier movement and transport. Option A is correct; coral, dunes, and distributaries belong to marine, aeolian, and fluvial environments.
