"Largest lake" sounds like one question, but this deck answers at least five: largest by area, by depth, by volume, by altitude, and by salinity. Lake Baikal is not the biggest lake, but it is the deepest and the fullest. The Caspian is the biggest, but it may not be a lake at all. If you learn the 50 cards as one list, the superlatives will blur together. Sort them by criterion and they stay separate.

What the deck covers
Caspian Sea, Lake Superior, Lake Victoria, Michigan-Huron and the Straits of Mackinac, Manitoulin Island, Lake Tanganyika, Lake Baikal, Great Bear Lake, Great Slave Lake (deepest in North America, 614 m), Lake Erie (smallest Great Lakes volume), Lake Ontario (lowest lying), Lake Ladoga and Lake Onega, Lake Turkana (largest permanent desert lake), Lake Winnipeg and Glacial Lake Agassiz, Lake Balkhash (fresh in the west, salty in the east), Titicaca and Issyk-Kul (mountain lakes), Lake Nicaragua and its bull sharks, Vänern (largest in the EU), Lake Tana (source of the Blue Nile), Taymyr, Peipus, the Aral Sea, Qinghai and Poyang, Lake Van, Lake of the Woods (~15,000 islands), Dubawnt, Uvs, Lake Melville and Lake Bangweulu.
Study tip 1: tag every card with its yardstick
Before your first review, add a tag to each card: area, depth, volume, altitude, salinity or record of its own kind (islands, fish species, frozen months). Then review one tag at a time. The area cards form a ranking you can repeat: Caspian, Superior, Victoria, Huron, Michigan, Tanganyika, Baikal, Great Bear, Malawi, Great Slave. Card 46 (Victoria 3rd, Tanganyika 6th, Malawi 9th) fits straight into that list.
Study tip 2: fix the cards that contradict each other
- Card 2 vs card 17. Card 2 calls Superior the second-largest lake. Card 17 says Michigan-Huron, counted as one lake (117,620 km²), is larger. Both are standard answers under different conventions, so add "if Michigan and Huron are counted separately" to card 2.
- Card 31. Before it shrank, the Aral Sea was the fourth-largest lake, not the third. Rewrite this card.
- Card 1. The Caspian's area changes with its water level. Most references give about 371,000 km², so treat 389,000 as an upper figure. Poyang (card 43) changes even more between the wet and dry seasons.
- Duplicates: 9/47 (Baikal volume), 7/38 (Tanganyika) and 21/48 (Balkhash). Merge each pair into a single card.
Pair it with rivers and mountains
Lakes, rivers and peaks all come down to rankings and superlatives. The same tagging method works on our major rivers guide and on the eight-thousanders deck.
