1. What is a periglacial lake?A periglacial lake is a lake that forms in very cold areas near old or current glaciers. It usually sits in a basin made by glaciers and is fed by meltwater and snow.
2. How do periglacial lakes form?They form when glaciers carve out or pile up land, creating a basin. Meltwater, snowmelt, or groundwater then fills that basin to become a lake.

Quaternary Period: The most recent geological period, spanning from about 2.6 million years ago to the present, characterized by repeated glaciations.
Proglacial Zone: The area immediately in front of a retreating glacier, often characterized by meltwater streams, outwash plains, and proglacial lakes.
