The Caspian Sea is the largest lake on Earth by both area and volume. It has a surface area of 371,000 square kilometres (143,000 square miles). Its volume is 78,200 cubic kilometres (18,800 cubic miles). The Caspian has for 40 to 44% of the total lake waters of the world.[2]

The Caspian sea is an endorheic body of water. It is bordered by Russia, Azerbaijan, Iran, Turkmenistan and Kazakhstan. It has a maximum depth of about 1,025 metres (3,363 ft). It is called a sea because when the Romans first arrived there, they tasted the water and found it to be salty. It has a salinity of approximately 1.2%, about a third the salinity of sea water.
