Is the Caspian Sea bigger than the Great Lakes combined?
By definition, a lake is a single body of water surrounded by land, so the quintet really should be called “the Great Lake.” That vast Eurasian pool called the Caspian Sea is bigger (143,244 square miles), but it's not fresh water.

The Caspian Sea is larger than the Lake Superior by surface area. The surface area of the Caspian Sea measures approximately 371, 000 square kilometers while the surface area of Lake Superior measures approximately 82,000 square kilometers.
Hydrology. The Caspian has characteristics common to both seas and lakes. It is often listed as the world's largest lake, although it is not freshwater: the 1.2% salinity classes it with brackish water bodies. It contains about 3.5 times as much water, by volume, as all five of North America's Great Lakes combined.
For some who study the Great Lakes, relative size is a defining factor, particularly with Lake Superior, which is the world's largest lake by surface area (aside from the much larger Caspian Sea—if you're willing to call it a lake).
Lake Ladoga, Russian Ladozhskoye Ozero or Ladozhskoe Ozero, largest lake in Europe, located in northwestern Russia about 25 miles (40 km) east of St. Petersburg.

Forming c. 12 million years ago, the largest lake ever known to have existed on Earth is Megalake Paratethys, which extended from the eastern Alps of Europe to what is now Kazakhstan in central Asia.
However, it is unique not only because of its size. As distinct from other lakes, the water of the Caspian is not fresh, but brackish. Each liter of Caspian water contains 10-13 grams of salt making this water unsuitable for drinking or irrigation.
3. Can you swim in the Caspian Sea? Most parts of the sea are perfect for swimming and relaxing. It has a fantastic climate, and not to forget that the sands in the Absheron peninsula, near Baku and other villages, are rich in minerals and salts with healing properties.
Geology of Lake InferiorLake Inferior is an underground lake that is located beneath Lake Superior. It is believed to be formed by a process known as karstification, which is the dissolution of limestone and dolomite rock. This process creates sinkholes, caves, and underground rivers and lakes.
While there have been past “sightings,” most have turned out to be pranks or misidentifications. The reality is that the largest of the Great Lakes (Lake Superior and Michigan) are extremely deep lakes that are too cold for sharks.
The United States Environmental Protection Agency, for example, describes them as “vast inland freshwater seas.” A seminal 2017 paper in Limnology and Oceanography, authored by some of the most influential researchers studying the lakes, also refers to them as 'inland seas.
