sandstone

Place of Origin:
China
Sandstone is a sedimentary rock. It usually has quartz in it. Grains of sand are weathered, which means blown around by the wind, or pushed around by rain, water, or erosion. When it settles down in one place, it forms layers that are stuck together with the minerals that fall between the grains of sand.
Sandstone is used in countertops, tiles, concrete, play sand, glass filing, polishing metal, sandblasting, and in making buildings.
