Negev Desert has lowest rate of erosion

Research suggests that the Negev Desert has the slowing rate of erosion in the world.

A research team calculated he speed of erosion by measuring the concentration of a radioactive isotype called berryllium-10 in chert stones collected from sites in the Negev,this isotype is formed when cosmic rays hit rock and soil,the concentrations of this isotype can indicate how long an object has been exposed to the sky.
