Which outcome occurs when glaciers retreat in a cirque basin and leave behind meltwater?

💡 Explanation

When a glacier retreats, it leaves behind depressions scoured into the bedrock because differential erosion occurs based on the rock's resistance, creating a lake within the cirque basin. Therefore, a tarn forms rather than, a kettle lake which involves glacial sediment deposits, an oxbow lake due to meandering rivers, or a fjord because of glacial valleys meeting the sea.
