The contrasting properties of these two substances, from their physical characteristics to their uses, perfectly illustrate the meaning of the idiom.

Chalk, a sedimentary rock, is formed over millions of years from the accumulation of the fossilized remains of marine organisms, primarily coccolithophores. Its soft, powdery texture and white color make it easily recognizable. Chalk is commonly used in classrooms for writing on blackboards, as a component in some paints and cosmetics, and as a soil amendment. Cheese, on the other hand, is a food product made from the curds of milk. The process of cheesemaking involves separating the solid curds from the liquid whey, followed by various aging and processing techniques. The resulting cheese can vary widely in texture, flavor, and appearance depending on the type of milk used, the aging process, and the addition of other ingredients.
