The journey of a river begins at its source, often a mountain or highland area. Starting as small streams, these tributaries join to form a larger, fast-flowing river in its youthful stage. As the river matures, it widens, meanders, and undergoes both erosion and deposition. In its old age, the flow slows, and the valley widens further. Finally, the river reaches its mouth, forming a delta as it deposits sediment into a larger body of water, such as an ocean or sea. Throughout its journey, a river shapes the landscape, sustains ecosystems, and provides resources for human activities. #rivers #geograpy #riverjourney
