Chalk is a type of limestone. Air and water don't wear chalk away easily, so when chalk is next to the sea, it often makes a large cliff. The "White Cliffs of Dover" in Kent, England are a good example of this. When chalk is near the top of the ground, it often makes chalk hills. Chalk holds water, so these chalk hills have a lot of water in them, and when the weather is very dry, water comes slowly from the chalk.
Blackboard chalk is not real chalk. It is really gypsum (calcium sulfate), but often people call it "chalk". People use it for drawing on hard things, because it is soft.

A chalk eraser or water can be used to clean the chalk marks away so the board is blank again. Shops usually sell blackboard chalk in sticks that are about 5 cm long.
