Why does a ribbon lake form in a glacial valley?
Answer and explanation
Correct answer: Water fills uneven overdeepened hollows and barriers in the valley floor
A ribbon lake is a long, narrow lake occupying a glacial valley. Moving ice erodes some sections of the valley floor more deeply than others, often where the bedrock is weaker or where ice pressure is concentrated. Rock thresholds or deposits can retain water in the overdeepened basin after deglaciation. Option A is correct; the alternatives describe coastal, aeolian, and karst processes.
