A valley is a depression on earth’s surface that is usually occupied by any water body either a river or a stream.
Due to running water and sometimes even wind, there occurs gradual wearing of land mass which ultimately leads to formation of valleys. The shape and size of the valleys is very much defined by the force which is causing its erosion, the rock characteristics and the slope of the land.
Hence, there are three types of valleys – a) U-shaped valleys b) V-shaped valleys and c) flat-floored valleys.
In which class of elements is there a greater range of properties, the metals or the nonmetals? Give an example to support your answer. Non-metals have greater range of properties given that they exist as solids, liquids and gases. And also that they can polymerize, crystallize and form organic compounds.
