Answer 2

Formation of Lake Baikal's Basin

Lake Baikal, located in Siberia, Russia, is the world's deepest and oldest freshwater lake, and it holds around 20% of the world's unfrozen surface freshwater. The formation of the lake and its basin is a result of various geological processes over millions of years.

Geological Activity: The formation of Lake Baikal's basin is primarily attributed to the process of tectonic rifting, which began around 25-30 million years ago. This rift zone is where the Earth's crust is being pulled apart, leading to the gradual formation of a basin and the eventual creation of the lake.

Tectonic Rifting: Tectonic rifting is a process where the Earth's lithosphere is being pulled apart, leading to the formation of a rift valley. In the case of Lake Baikal, this process resulted in the creation of a deep, elongated basin, which eventually became filled with water, forming the lake.

Geological Features: The lake's basin is characterized by its unique geological features, including its depth, which reaches a maximum of 1,642 meters, making it the world's deepest lake, and its age, estimated to be around 25-30 million years old.

Conclusion

The formation of Lake Baikal's basin is a result of tectonic rifting, a geological process that occurred over millions of years, leading to the creation of a deep and ancient freshwater lake.
