So It Basically Depends On You, Whether You Want To Call Caspian Sea, A Sea Or A Lake.



The Caspian Sea, Like The Aral Sea, Black Sea, And Lake Urmia, Was A Part Of The Ancient Paratethys Sea. It Got Landlocked 5.5 Million Years Ago As A Result Of Tectonic Uplift And Sea-level Fall. Hence, The Seafloor Of The Caspian Sea Is Composed Of Oceanic Basalt And Not Continental Granite.
