Explanation: ALLUVIAL  soil  is  formed  when  a  soil-carrying  stream  gradually  loses  its  carrying capacity   with   decreasing   velocity.   In   slowing down,  a  river  does  not  have  sufficient  power  to keep the large particles of soil suspended; these particles settle to the riverbed. Further decrease in velocity causes smaller particles to settle. As the  river  becomes  slow  and  sluggish ,  it holds only the extremely fine particles in suspension. These particles are deposited, finally, at the mouth of the river, where they form DELTAS of fine-grained  soil.
