The Baikal Rift Zone is a geological feature located in Siberia, Russia. It is characterized by a series of faults and fissures that have formed as the Earth's crust is pulled apart. This rift zone is home to Lake Baikal, the world's deepest and oldest freshwater lake, which is a significant geological and ecological site. The rift zone is an active area of tectonic activity, where the movement of the Earth's plates continues to shape the landscape. It is also known for its unique biodiversity, including species like the Baikal seal and various endemic fish, making it an important area for scientific research and conservation efforts.
