Munsell chart is used to study :

  • A.Density of soil
  • B.Refractive index of soil
  • C.Particle size of soil
  • D.Colour of soil

Answer: D

The Munsell chart is used to study the colour of soil.

The Munsell soil colour charts describe colour by hue, value (lightness) and chroma (intensity), with a notation such as 10YR 4/3. Forensic scientists compare questioned and known soil samples, dry and moist, against the charts so that colour is recorded in a standard way rather than by subjective names.

Density is measured with a density gradient column, refractive index of mineral grains under the microscope, and particle size by sieving or sedimentation. None uses the Munsell chart.
