A chalkboard is tough and scrapes the chalk which leaves chalk behind so you can write. Glass is smooth and doesn't scrape the chalk, so it leaves no marks.
It is pretty much the same. Chalk and limestone are made of the same elements, but to to make chalk they change the limestone a bit. First they change the shape and then make it smooth. I hope that helps!
It always makes some kind of sound. The more smooth, dry or shiny the surfaces of chalk and board, the more squeaky it becomes.

It is easy to write on a rough blackboard. The friction between the chalk and the rough surface is what allows the chalk to leave behind the chalk dust that we see. Actually it would impossible to write on a theoretically smooth blackboard. Without the friction, the chalk would not leave any residue!
Chalk can be used to write on any hard dark surface that is slightly abrasive (not polished smooth).
look like a cylinder, cirgarette, stick. feel powdery, smooth, and hard
A chalk is used to ready a leather cue tip - the substance is not chalk but an abrasive of the type used in sandpaper. In addition, a cloth or leather may be used to rub the taper to be sure it is clean and smooth.
SANDie Well it will be like sand, or it could be a powder. If it is a blue kind of chalk, when you crush the blue chalk, it will be blue. Sometimes, it could be a nice smooth powder. Sometimes, it could be into pieces instead. You have to crush it more to make it like sand or powder. But sand has rocks and hard ones. So this might be powder.
