Judy used the following soil triangle to identify a sample of soil as silty clay.

Soil texture triangle. Clay soil is approximately 45 percent or less sand, 50 percent or more clay, and 40 percent or less silt. Silty loam soil is approximately 50 percent or less sand, 30 percent or less clay, and 50 percent or more silt. Sandy clay soil is approximately 45 to 65 percent sand, 35 to 55 percent clay, and 25 percent or less silt. Sandy clay loam soil is approximately 45 to 80 percent sand, 20 to 35 percent clay, and 35 percent or less silt.

Which description of soil likely allowed Judy to make this identification? (2 points)

a
Mostly large particles, with a gritty texture, 75% clay, 15% sand, and 10% silt

b
Mostly large particles, with a sticky texture, 65% clay, 10% sand, and 25% silt

c
Mostly small particles, with a sticky texture, 50% clay and 5% sand, and 45% silt

d
Mostly small particles, with a smooth texture, 30% clay, and 25% sand, 45% silt

Explanation: I worked it our w/ the triangle and this seemed the most logical answer. plus had the same question on a test ~5min before this post so I know for sure its right.

Soil texture or Soil profiling is referred to as the proportion of primarily three different types of particles, clay, sand, and silt.

The description that is similar to Judy's soil triangle is that most small particles, with a smooth texture, are 10% sand, 50% clay, and 40% silt.

The soil profiling can be explained as:

1. Clay is one of the smoothest and fine particles of the soil. It has a diameter of fewer than 0.2 millimeters. Clay soil is 40% or more is clay, less than 40% is silt, and 45% or less is sand.

2. Sand is a coarse particle and is the largest mineral in the soil. The particle is gritty and has a diameter of 0.05 to 0.02 mm.

3. Silt is found in a high percentage of the soil and gives a smooth texture to the soil.

Thus, the correct answer is Option C.
