Fluvial (River) ActionNone |
River valleys are landforms created by the erosive action of rivers over long periods of time. These valleys are carved into the Earth's surface as rivers flow through various landscapes, eroding the surrounding land and shaping the terrain. River valleys can vary in size, shape, and characteristics depending on the geology, climate, and tectonic activity of the region. River valleys are dynamic systems that change over time due to erosion and deposition. They play a critical role in shaping the landscape, providing habitats for diverse ecosystems, and influencing human settlement and development throughout history. |
