The Elbe River was formed through a combination of geological processes over millions of years. It originated from the confluence of two smaller rivers, the White Elster and the Black Elster, in the Czech Republic. The river then flowed northward, carving its path through the landscape through erosion and sediment deposition. Glacial activity during the Ice Age also played a significant role in shaping the course of the Elbe River, creating the diverse landscapes that it flows through today. **
