Do All Rivers Start at the Same Place? Understanding River Sources

Rivers originate from diverse sources: melting snow and glaciers in mountains (e.g., Nile, Colorado), hillside runoff (e.g., Thames), groundwater springs (e.g., San Marcos River), lake outlets (e.g., St. Marys River from Lake Superior), and glacial meltwater (e.g., Rhône). The exact starting point depends on local topography, climate, and geology.
