The answer depends on a variety of variables, but the simplest is that barring further action on the pencil mark (rubbing, wear, etc), it will last as long as the paper.
Mark-making is the process of applying pencil to paper. I would broaden this to include applying anything to anything! (scratching marks in plaster, using pen and ink, paint on canvas, anything that leaves a mark on the page could be considered mark making that's what is so nice about it:o)
pencil
It allows you to mark on glass to label something during a lab and then later wash off the grease.
THe rubber absorbs the pen or pencil mark - hence, the mark is gone! think of blotting a stain from a carpet - the rag or sponge absorbs the stain ...same principle for pens and pencils
The 'h' and 'b' rating combined with a number refer to the hardness of the graphite in a pencil. h-hard and b-soft. So the higher the number the more hard or soft it is. Hard graphite imparts much lighter marks to paper, while softer graphite makes a much darker mark. So a 6b pencil is very soft and draws quite dark while a 6h pencil is very hard and draws very light marks.
When a pencil is rubbed on paper fiction causes a small amount of the graphite from the core of the pencil to be left on the paper. This leaves a visible mark.
Yes, better than ink!
It is the part of the pencil that makes the mark on the paper. Pencils used to use lead for this but the lead has been replaced with graphite.
Hold and press the pencil down and drag it across the paper to create friction between the lead and the paper and the lead will produce a mark on the paper which can be rubbed out. You should already know this when you were 5 years old
No, because graphite is structured in such a way that the layers glide. Whilst drawing with a pencil the layers are gliding which is leaving a mark on the paper, because the substances inside the pencil are being rubbed off. Hence, this is a physical change rather than a chemical change. The graphite remains graphite, the paper remains paper.

The mineral graphite is soft enough to leave a mark on paper. We use graphite, which is a form of carbon, as pencil lead. And it works pretty darn well at leaving marks on paper.

About 3 seconds ago. "Lead" pencils are the graphite ones we use all the time, those yellow things that you sharpen in a pencil sharpener. Lead is dark gray and leaves such a mark on paper. It isn't really lead in the pencil, we just say that.

It depends on the size of the paper and the size of the tally marks. A standard 8 1/2 x 11 sheet wouldn't hold them if you used a pencil to mark them. But paper comes in rolls thousands of feet long, and you could pencil them all in on one of those. Additionally, with the contemporary automated printing techniques, a laser could be programmed to "burn" a million marks on a sheet of paper small enough that you could fold it up and carry it in a file folder with no difficulty.
