Answer 2

The factors that decide the soil color are:

Origin and Age

• Soil color mainly depends on the material it originated from.
• The color of the soil becomes lighter as it gets aged, as the organic matter gets broken down due to weathering.

Organic matter

• The type of organic matter present in the soil determines its color.
• Humus gives the soil a dark color.

Iron content

• The presence of iron and its difference in concentration gives the soil a wide range of colors.
• Iron oxide reacts with the soil moisture to give it a yellow color.

It is difficult to make mud balls using sand because;

• Sand does not contain any clay content.
• It is the presence of clay that allows soil particles to stick together.
