Best Answer

It can be rough or smooth. If it is more broad-grained (granular), it will feel rough to you, but it can be very fine-grained, such as when it is in the form we call alabaster, and that will feel very smooth. You can also smooth out a rough piece of gypsum by polishing it.

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!
