Which outcome occurs when glacial advance into periglacial lakes?

💡 Explanation

Kettle lake formation arises from glacial retreat. Deposition of till by the melting glacier leaves behind sediment enclosing ice blocks. These form depressions that fill kettle lakes because of melting, rather than the opposite, therefore its a strengthening outcome.
