The exact shape will depend on the characteristics of the stream flowing through it. Continuously flowing glaciers – especially in the ice age – and large-sized glaciers carve wide, deep incised valleys, sometimes with valley steps that reflect differing erosion rates. Rivers with steep gradients, as in mountain ranges, produce steep walls and a bottom. When the ice recedes or thaws, the valley remains, often littered with small boulders that were transported within the ice. In the Alps – e.g. They also have broad, flat valley floors.

As the ice melts and retreats, the valley is left with very steep sides and a wide, flat floor. Dades River. U-shaped valleys are formed by glacial erosion as massive mountain glaciers moved slowly down mountain slopes during the last glaciation. Shallower slopes may produce broader and gentler valleys. They are characterized by steep sides that curve in at the base of the valley wall. Whereas a stream only occupies the floor (or a main portion of it) in a V-shaped valley, a valley glacier occupies the entire valley, eroding both the sides and the floor as it moves, deepening and widening the … They flow down pre-existing V-shaped valleys created by streams to form U-shaped valleys. Valley of Heart’s Delight. Death Valley, also located in America is so known because of the extreme hot temperatures it experiences. A hollow is a small valley or dry stream bed. Their cross-sections exhibit steep-sided flanks similar to fjord walls, and their flat bottoms are typical of subglacial glacial erosion. Many villages are located here (esp. A valley in its broadest geographic sense is also known as a dale. When the glacier melts, the landscape is transformed and the U-shaped valleys are clearly visible. Silicon Valley also accounts for one-third of all of the venture capital investment in the United States, which has helped it to become a leading hub and startup ecosystem for high-tech innovation.

Porsmork Valley, Iceland. It typically ranges from about one to ten kilometers in width and is commonly filled with mountain sediments.

Side valleys are rather V than U-shaped; near the mouth waterfalls are possible if it is a hanging valley. To determine the direction water is flowing, look at the contour lines. The terms U-shaped and V-shaped are descriptive terms of geography to characterize the form of valleys. Glacier movement is driven by gravity. The shape of valleys varies but they are typically steep-sided canyons or broad plains, however their form depends on what is eroding it, the slope of the land, the type of rock or soil and the amount of time the land has been eroded. The Barossa Valley wine region is one of Australia's oldest and most premier wine regions. The mouth of Ikjefjord is only 50 meters deep while the main fjord is around 1300 meters at the same point.
