Details About Which is the largest lake in the world:

In terms of surface area, the Caspian Sea is thought to be the biggest lake in the world. It is roughly 371,000 km² (143,243 mi²) in size. Though sometimes called a “sea,” it is more accurately described as a lake with freshwater and saltwater features. It is isolated from all oceans and is landlocked1. Its enormous area, which touches five nations (Russia, Kazakhstan, Turkmenistan, Iran, and Azerbaijan), influences regional geopolitics. On the other hand, Lake Baikal in Russia is the world’s largest freshwater lake when it comes to water volume. It holds roughly 20% of the fresh surface water on Earth or 23,013 cubic kilometers (5,521 cubic miles) of water. This amount of water is roughly equal to the combined volume of all five Great Lakes in North America.
