Based on the soil texture diagram, which percentages of sand, clay, and silt would result in sandy clay?
a. 60 percent sand, 10 percent clay, 30 percent silt
b. 80 percent sand, 10 percent clay, 10 percent silt
c. 50 percent sand, 40 percent clay, 10 percent silt
d. 20 percent sand, 60 percent clay, 20 percent silt

C.  50 percent sand, 40 percent clay,  10 percent silt

Explanation:

To read the soil texture triangle, remember the following:

1. Clay = horizontal        -

2. Sand = diagonal going up and to the left   \

3. Silt = diagonal going down and to the left  /

Refer to the picture attached so you can understand this better.

To get the percentage of the composition of your sample, just follow the lines that meet at the point in your soil texture triangle.  The number at the end of the line would be the percentage.
