Grains are simply the hard, edible seeds of grass-like plants. There are many varieties and the most common are wheat, corn, oats and rice. They are one of the most-consumed foods worldwide and the primary source of nutrition and energy for many populations around the world.
Sand is a naturally occurring granular material composed of finely divided rock and mineral particles. It is defined by size, being finer than gravel and coarser than silt. Sand can also refer to a textural class of soil or soil type; i.e., a soil containing more than 85 percent sand-sized particles by mass. The composition of sand varies, depending on the local rock sources and conditions, but the most common constituent of sand in inland continental settings and non-tropical coastal settings is silica (silicon dioxide, or SiO 2), usually in the form of quartz.
