4. This is a diagram of a sol texture triangle. Farmers can use this chart to identify the type of soil found on their land and determine the likelihood of erosion and other important factors. What type of soil does a farmer have if the soil contains 40% sand, 40 silt, and 20% clay?

Type of soil : Loam

A mixture is a combination of two or more single substances. The properties of the mixture component are not lost / unchanged as in compounds.

The mixture can be divided into a homogeneous mixture if the composition/ ratio of each substance in the mixture is the same and a heterogeneous mixture if the ratio of the composition of the substances is not the same (can be varied) in each place.

Soil is part of a mixture that has a different composition

To find the type of soil, we just need to draw a line of intersection between the 3 compositions shown

So the soil contains 40% sand, 40 silt, and 20% clay : Loam
