Consider the following differences between dry deposition and wet deposition:

  1. While in case of wet deposition the inputs enter the atmosphere in the form of gases, for dry deposition the input enters the air usually as dust from industrial area
  2. While wet deposition occurs through rainfall, dry deposition occurs through dust foil
