Question

Как образовалась озерная котловина байкала

Answer 1

Примерно 20-25 лет назад в этом районе существовали мелководные озера остатки древнего моря. Потом там начались движения и сопровождались разломы вулканическо вулканическо деятельностьями и землетрясения. И потом при появлении горных хребтов котлованы были заполнены водой Байкала. Вот и все спасибо!

Answer 2

Formation of the Baikal Rift Zone and Lake Baikal

Lake Baikal, located in Siberia, Russia, is the deepest and oldest freshwater lake in the world. The formation of the Baikal Rift Zone, where Lake Baikal is situated, is a result of tectonic activity and geological processes over millions of years.

Tectonic Activity and Rift Formation: The Baikal Rift Zone was formed due to the tectonic activity that led to the splitting of the Earth's crust, creating a rift valley. This rift valley eventually filled with water, forming Lake Baikal [[5]](https://cyberleninka.ru/article/n/modeli-evolyutsii-ozernyh-basseynov-vostochnoy-sibiri-v-pozdnem-pleystotsene-i-golotsene).

Geological and Geomorphological Processes: The geological and geomorphological materials in the region have been analyzed to understand the evolution of the lake basins in Eastern Siberia during the Late Pleistocene and Holocene periods [[5]](https://cyberleninka.ru/article/n/modeli-evolyutsii-ozernyh-basseynov-vostochnoy-sibiri-v-pozdnem-pleystotsene-i-golotsene).

Timeline of Formation: The formation of the Baikal Rift Zone and Lake Baikal occurred over an extensive period, with the rift zone being created millions of years ago and the lake basin evolving over subsequent geological epochs [[5]](https://cyberleninka.ru/article/n/modeli-evolyutsii-ozernyh-basseynov-vostochnoy-sibiri-v-pozdnem-pleystotsene-i-golotsene).

In summary, the Baikal Rift Zone, which encompasses Lake Baikal, was formed as a result of tectonic activity and geological processes over millions of years, leading to the creation of the world's deepest and oldest freshwater lake.
