Which of the following is classified as boulders in soil grading?

Boulders in soil grading are classified as particles that are larger than 12 inches in diameter. This size classification is important in soil mechanics and construction applications, as it helps in understanding the physical characteristics of the soil and its suitability for various engineering purposes. Choosing this classification is related to the context of grading soils based on particle size, which significantly affects soil behavior, stability, and drainage qualities. When dealing with soil for construction or landscaping purposes, knowing the size of the components, such as boulders, helps in design decisions and material handling. The other size ranges provided do not fit the definition of boulders. For instance, the range of 0.075 mm to 2 mm refers to silt and fine sand, while 3" to 12" includes gravel-sized materials, neither of which can be classified as boulders. The size less than 0.002 mm pertains to clay particles, which are much smaller and again, do not fall into the boulder category. Thus, the correct answer identifies the appropriately sized particles in the context of soil grading.
