Glacial lakes are bodies of water formed in a basin by melted ice sheets or glaciers. They are often found in high mountain regions and are known for their stunning beauty. Synonyms for glacial lake include tarn, cirque lake, moraine lake, kettle lake, and fjord lake. Tarns are small, shallow, and often circular glacial lakes found on mountain slopes. Cirque lakes, on the other hand, are typically larger and shaped like bowls. Moraine lakes are created by rocks and sediments deposited by a glacier, while kettle lakes form in depressions created by melted ice blocks. Lastly, fjord lakes are formed when glaciers carve out deep valleys that later fill with seawater.
