Answer for screen readers
Sand is a solid that behaves like a liquid under certain conditions, but each grain of sand maintains its solid structure.
More Information
Sand consists of solid grains of SiO2 (silicon dioxide) crystals. Although it can be poured and take the shape of its container, each individual grain remains a solid.
Tips
A common mistake is to assume that sand is a liquid because it flows. However, the individual grains do not change shape, which classifies them as solids.
