most common type of valley in the world
Valley A valley formed by flowing water, or river valley, is usually V-shaped. The exact shape will depend on the characteristics of the stream flowing through it. Rivers with steep gradients, as in mountain ranges, produce steep walls and a bottom. Shallower slopes may produce broader and gentler valleys. However, in the lowest stretch of a river, where it approaches its base level, it begins to deposit sediment and the valley bottom becomes a floodplain.
Valley of the Kings The Valley of the Kings (Arabic: وادي الملوك‎ Wādī al Mulūk, Coptic: ϫⲏⲙⲉ[1]), the Valley of the Gates of the Kings (Arabic: وادي ابواب الملوك‎ Wādī Abwāb al Mulūk),[2] is a valley in Egypt where, for a period of nearly 500 years from the 16th to 11th century BC, rock cut tombs were excavated for the Pharaohs and powerful nobles of the New Kingdom (the Eighteenth to the Twentieth Dynasties of Ancient Egypt).[3][4]
