hello, i hate the feeling of chalk
Chalk is actually a rock that is soft, white, and porous.  It's made of calcite!
yeah, but it is weird in thinking it is a rock
It is!  It forms as calcite shells accumulate in deep marine conditions.
 so it came from living beings, interesting
Yes it does, and is a form of calcium carbonate.
so you can eat chalk if you have an upset stomach :)
Chalk can form steep cliffs, since it does not slump like the clay that it is usually associated with.
