soil taxonomy

There are 11 orders of soils (histosols, entisols, inceptisols,
andisols, mollisols, ultisols, alfisols, spodosols, oxisols,vertisols,
& aridisols). Choose 3 of the mentioned orders. List down the mineral
contents in percentage(%) of each chosen orders. Then, discuss which
factors (terrain,climate,biological weathering,time,parentmaterial)of
soil formation were involved in forming these 3 soils and the relative
strengths of the factors.
