Gully Erosion
Plateau. Valley. Dune.
It depends on which valley you're talking about, but most were created by erosion. Either that or they're the space between two hills/mountains.
A valley typically is created by erosion, either by water or a glacier. I suppose a valley could also be created as two tectonic plates separate, such as the Great Rift Valley.
The entire valley is from erosion and glaciers.
Erosion played a crucial role in shaping Death Valley through a combination of weathering, water runoff, and the movement of ice and wind. Over millions of years, rainwater and meltwater from surrounding mountains eroded the rock and soil, carrying sediment into the valley. Additionally, wind erosion helped to sculpt the landscape, creating the valley's iconic features such as dunes and salt flats. Tectonic activity also contributed by lowering the valley floor while raising the surrounding mountains, intensifying the erosive processes.

Erosion!
A 'U' shaped valley indicates glacial erosion.
No, the Ohio Valley is not a rift valley. It is primarily a river valley formed by the erosion of the Ohio River and its tributaries. Rift valleys are created by tectonic processes, where tectonic plates move apart, leading to the formation of low-lying areas. The Ohio Valley, on the other hand, is shaped by sedimentary processes and river erosion rather than tectonic activity.
Water erosion
glacier erosion
Jiuzhaigou Valley was created by the geological movement of the Earth's crust around 2-3 million years ago. The valley's distinctive landscape features, including its deep gorges, colorful lakes, and waterfalls, are the result of glacial erosion and tectonic activity over time.
