4. North America – Lake Michigan-Huron/Lake Superior
The combined waters of the Lake Michigan and Lake Huron is sometimes regarded as one single body of water. The fact that the lakes are connected to each other via the Straits of Mackinac and their water levels are in near-equilibrium allows the classification of these lakes as one single entity. In this case, the Lake Michigan-Huron is the largest lake in North America. It occupies an area of 117,300 square km and the waters are shared by Canada and the US. However, if the lakes are treated as separate lakes, then Lake Superior replaces the position as North America’s biggest lake. Lake Superior occupies a surface area of 117,300 square km.

Lake Eyre is the largest lake in Oceania and also has the lowest elevation point in Australia. The lake occupies an area of 9,500 square km. The endorheic lake is quite shallow with an average depth of only 5 ft. The volume of the lake varies considerably throughout the year and so does the salinity level of its waters. Lake Eyre is named after the first European who discovered it, Edward John Eyre.
1. Antarctica – Lake Vostok

The presence of the lake was first suggested by Andrey Kapitsa, a Russian geographer. Its presence was confirmed in 1993.
