Chalk is a type of soft rock that in school settings is typically used for writing information on blackboards.
Peeves the poltergeist was known for regularly pelting chalk at unfortunate students of Hogwarts School of Witchcraft and Wizardry who were late for class. Early in the 1991-1992 school year, he was discovered by Professor Minerva McGonagall using chalk to write rude words on a blackboard. When she ordered him out of the classroom, he chucked the chalk in a bin.
