Flat-floored valleys, also known as "box canyons," are generally formed by the erosion of softer rock layers between more resistant layers. Over time, water flow and erosion gradually carve out these valleys, resulting in flat floors due to the differential erosion rates of the various rock layers. Additionally, tectonic forces and glacial activity can also contribute to the formation of flat-floored valleys.

Valleys can be formed by a combination of erosion and weathering. Erosion, which is the process of wearing away rock and soil, contributes to the shaping of valleys by moving sediment and carving out the land. Weathering breaks down rocks and contributes to the gradual formation of valleys over time.
Hanging valleys are formed when smaller glaciers flowing from tributary valleys join a larger glacier in a main valley. As the larger glacier is more powerful, it erodes the main valley deeper than the tributary valleys. This results in the tributary valleys being left at higher elevations once the glaciers retreat, creating the characteristic "hanging" appearance.
Yes, valleys are primarily formed by a combination of weathering and erosion processes over time. Weathering breaks down rocks into smaller particles, while erosion transports these particles away, often carving out valleys in the landscape. Factors such as water, wind, ice, and gravity all play a role in shaping valleys through weathering and erosion.
Valleys are typically considered landforms resulting from erosion, which is a destructive force. However, in some cases, valleys can also be formed through constructive processes such as faulting or volcanic activity. Overall, the formation of valleys involves a combination of both constructive and destructive forces.
There are plenty of valleys in Wales.V-shaped valleys are formed by water flow.U-shaped valleys are formed by glaciation.
River valleys are formed by stream erosion.
There are several types of valleys, including V-shaped valleys formed by erosion from rivers, U-shaped valleys carved by glaciers, rift valleys formed by tectonic activity, and hanging valleys created when smaller tributary valleys flow into larger main valleys.
rift valleys
V-shaped valleys are formed by rivers.

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.
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.
