River valleys are formed by stream erosion.
V-valley refers to a type of valley on a topographic map that has a V-shaped profile, typically formed by erosion from a river or stream. U-valley refers to a valley with a U-shaped profile, typically formed by glacial erosion. V-valleys are more narrow and have steeper sides compared to U-valleys.
The different types of river valleys include V-shaped valleys, U-shaped valleys, and canyon valleys. V-shaped valleys are typically narrow with steep sides, carved by erosion from a river. U-shaped valleys are wider and have more gradual slopes, formed by glaciers. Canyon valleys are deep and narrow with steep sides, often formed by a combination of tectonic activity and erosion.
River valleys: V-shaped valleys created by the erosive action of flowing water. Meanders: Curving bends in a river formed by lateral erosion. Oxbow lakes: U-shaped bodies of water formed when a meander is cut off from the main river channel. River cliffs: Steep, exposed banks along the edge of a river created by erosion. River deltas: Triangular landforms at the mouth of a river formed by deposition of sediments carried by the river.
Most early civilizations were formed around river valleys.
The Harappan culture formed in two river valleys; the Indus in Pakistan, and the Sarasvati in north India.
Through erosion, a river creates valleys, waterfalls, flood plains, meanders, and oxbow lakes.
River valleys are primarily formed by the erosion caused by flowing water over a long period of time. The force of the water wears away the surrounding land, deepening and widening the valley over time. Additionally, other factors such as tectonic activity and glaciation can also contribute to the formation of river valleys.
Bored or U-shaped valleys in mountain river valleys are primarily formed by glacial erosion. As glaciers advance, they carve out the landscape, widening and deepening valleys through the process of abrasion and plucking. This results in the characteristic U-shape, contrasting with V-shaped valleys formed by river erosion. Over time, the immense weight and movement of the glacier reshape the terrain, leading to the distinctive valley profile.
Ruins of early civilizations were most commonly found in valleys formed by the flow of dried out rivers.

When running water erodes rock and soil, it can create landforms such as valleys, canyons, gorges, and river deltas. Valleys and canyons are formed by the gradual erosion of the surrounding landscape, while river deltas are formed when sediment carried by the river is deposited at its mouth. Gorges are narrow valleys with steep sides, often carved out by fast-moving rivers.
