Microchips in lieu of labels

We have so much discussion on various forums over what is sand or grit or gravel; but rock mulch! How large is that and what shape? or is it just another name for some of the 3 above.

Pea gravel. What I believe is called shingle in the U.K. Years of applying the “annual approved topdressing” (I read a lot of Graham Stuart Thomas), the raised beds have become mostly gravel, with some clay.
Here, we mulch with shingle, but only after a hailstorm.
