Significance of weathering

  • Weathering is the first step in formation of soils.
  • Weathering of rocks and deposits helps in the enrichment and concentrations of certain valuable ores of iron, manganese, aluminium, copper etc.
  • Weathering helps in soil enrichment.
  • Without weathering, the concentration of the same valuable material may not be sufficient and economically viable to exploit, process and refine. This is what is called enrichment.
