Här är varför:
* Basal Cleavage: This occurs when the mineral breaks along flat planes parallel to the base of the crystal. This is often seen in minerals with layered structures, where the bonds within the layers are strong but the bonds between layers are weaker.
* Exempel: Mica, a common mineral with basal cleavage, breaks into thin, flexible sheets due to its layered structure.
Other types of cleavage, such as prismatic and cubic , result in different shapes and forms.
