The four Siberian rivers—Lena, Yenisei, Ob, and Amur—are unusual due to their extreme lengths and the unique environments they traverse, flowing through some of the coldest regions on Earth. They experience significant seasonal variations, with freezing in winter and rapid thawing in spring, leading to dramatic flooding. Additionally, these rivers play a crucial role in the local ecosystem and economy, supporting diverse wildlife and communities despite the harsh climate.
