Rock vs. stone: what’s the difference?
The short answer
Rock is the general and scientific word for the hard mineral material of the earth, and for large masses of it (a rock face). Stone is used for the material as something to build with (a stone wall) and for small pieces. In American English, rock is also common for small pieces (He threw a rock), where British speakers usually say stone.
What they have in common
Both rock and stone refer to naturally occurring solid mineral materials that are found on Earth. They are often used interchangeably in casual language to describe hard, solid pieces of earth’s crust.
