Question

Quizplus · Accepted Answer

The gritty feel between the fingers is the best way to distinguish sand grains from silt grains as sand grains are larger and coarser than silt grains, and thus can be felt as gritty between the fingers. Seeing individual grains and composition may not always be a reliable way to differentiate between the two. A microscope can be used for detailed examination, but it's not necessary for general differentiation.
