Answer:
Kettle lake
Step-by-step explanation:
A kettle lake forms when a receeding glaciers leaves glacier behind in a shallow depression called a kettle.
Kettles and kettle lakes are products of glacier deposition. They are mostly attributed to the receeding phase of a glacier. The mouth of a retreating glacier are usually laden with a mix of melt water and sediments. As the glacier continues to retreat, it leaves behind stagnant ice that must have been buried with the sediment. When the ice melts, a kettle which is an hollow depression forms and the water in it makes it a kettle lake.
