Review Minerals-5

When you break the mineral calcite, it breaks into shapes with flat, smooth sides. This is an example of:

  1. Cleavage

    Yes! A mineral has cleavage when it breaks to form flat, smooth surfaces.
  2. Fracture

    No. There are different kinds of fractures, but none of them form flat, smooth surfaces.
  3. Conchoidal

    No. A conchoidal fracture is the shell-shaped break that is commonly seen when glass breaks. A conchoidal fracture is not flat.
  4. Hardness

    No. Hardness tells us how easily a mineral can be scratched, not how it breaks.
