Rivers Shape Everything

From the moment a raindrop hits the ground, rivers become agents of transformation:

• Erosion — rivers carve canyons over millions of years; the Colorado River cut the Grand Canyon over 5-6 million years
• Deposition — sediment builds deltas, floodplains, and the fertile valleys where civilizations take root
• Transport — before roads existed, rivers were the main way to move goods and people over long distances

Rivers do not just flow through terrain. They create worlds, shaping every valley, gorge, and fertile plain you see.
