Sandstone is made of tiny pieces of sand you can see and feel. You can actually scratch away grains of sand from a piece of sandstone. It forms when wind, ice, and water carry away grains of sand and drop them someplace new—usually at the bottom and along sides of rivers, lakes, and coastlines.

At the most basic level, sandstone is literally sand that has been turned to stone. It is made up of bits and pieces of other rocks and minerals that have been compacted and cemented together.
