What is cleavage?
Mineral Cleavage: Cleavage is one characteristic of minerals that refers to the tendency to split along planes of weakness. Female Cleavage: The space between a woman'…s breasts is her cleavage. When women wear low-cut clothing, their cleavage shows. For example, a low-cut wedding dress shows cleavage Plumber's Cleavage: Plumbers often exhibit their cleavage when they squat to fix your sink. It is best to look away. A word about the word: "Cleave" is one of the few words in the English language that is its own antonym. "To cleave" can mean "to hold fast to" and "to break or cut away from". Cleavage describes the break in a mineral. It is one of the physical properties that people test to identify minerals. Cleavage means that a mineral breaks cleanly, with no jagged edges. If it does have jagged edges than it is a fracture. When a mineral has cleavage then that means the it has a cubic structure, and therefore, will break cleanly and smoothly. Let's say that you smash a rock and it breaks everywhere, and has rough, jagged edges. It has fractured. It also has no cleavage. If you break another one and it's sides when broken are smooth and straight, it has cleavage. Cleavage usually refers to the exposure or partial exposure of the separation, or lack of, between a woman's breasts. It can also refer to a division between two groups of people or things. (MORE)
