Detalhes da Resposta

The plains formed when the slopes of mountains are worn back in arid and semi-arid regions by mechanical weathering is called "Pediplains". Pediplains are a type of plain that form as a result of the gradual erosion and weathering of mountains and hills. They typically occur in arid and semi-arid regions where there is little vegetation to protect the land from erosion. Over time, as the wind, rain, and other natural forces wear away at the mountain slopes, sediment is carried downhill and deposited on the surrounding plain. This sediment can be made up of rocks, sand, and soil, and can create a relatively flat and gently sloping plain that extends out from the base of the mountain. Unlike other types of plains, such as alluvial plains or outwash plains, which are formed by water deposition, pediplains are formed by the mechanical weathering and erosion of rock and soil. They are typically found in regions where there is little precipitation and where the climate is dry and hot, which can help to speed up the weathering process.
