Which of the following soil particle types is the largest?
a. sand b. silt c. clay d. potassium

The right answer is A. sand.

Sands are grains of rocks or minerals with a diameter between 0.0625 mm and 2 mm (or 4.75 mm and 5 mm, depending on the classification system used). We use here the unified soil classification system (A. S. T. M.), used in the field of geotechnics and civil engineering in North America. The following table shows the lower and upper grain diameter limits and the corresponding A. S. T. M. sieve numbers, for three sand grain size ranges: coarse sand, medium sand, and fine sand.
