Answer: Determining color
Explanation:
A soil is an aggregate of solid, liquid and gases. It is formed by the weathering of the parent rock material. The features of the soil may vary due to the composition, texture, color and grain size. Color is the feature of the soil which is affected by the pH, presence of inorganic and organic content. The Munshell chart is a standard chart which includes all types of soil color. This can help in comparing and determining the color of the soil sample.
