How Are Rivers Formed?

Rivers are crucial for human life and ecosystems, providing resources like food, energy, and transportation. They typically form in mountains, where glaciers and precipitation create tributaries that join to form larger rivers. Erosion shapes the landscape, creating features like waterfalls. Rivers may end in deltas, where they meet the ocean. The Amazon River, the largest on Earth, is fed by a vast drainage basin. Rivers are vital for the Earth's water cycle and ecological balance.
