When a mineral splits easily along flat surfaces the mineral has this property?
Cleavage – The tendency of a mineral to break along flat planar surfaces as determined by the structure of its crystal lattice. These two-dimensional surfaces are known as cleavage planes and are caused by the alignment of weaker bonds between atoms in the crystal lattice.
What is the property of a mineral splitting evenly along a flat surface?
Cleavage is the property of splitting evenly along flat surfaces.
What is cleavage mineral?
Cleavage refers to the way some minerals break along certain lines of weakness in their structure. Cleavages are described in terms of their quality – how smoothly the mineral breaks – and their difficulty – how easy, or how hard, it is to produce the cleavage.
How a mineral splits apart when it does not break evenly?
A mineral that splits easily along flat surfaces has the property called cleavage. Most minerals do not split apart evenly. Instead, they have a characteristic type of fracture, which describes how a mineral looks when it breaks apart in an irregular way.
How a mineral breaks apart unevenly is known as?
A mineral that splits easily along flat surfaces has the property called CLEAVAGE. How a mineral looks when it breaks apart in an irregular way is called FRACTURE. (8) Special Properties – some minerals can be identified by special physical properties.
What are cracks in rocks called?
A fracture is any separation in a geologic formation, such as a joint or a fault that divides the rock into two or more pieces. A fracture will sometimes form a deep fissure or crevice in the rock.
What is Luster property?
Ans: Luster is a property that defines how light is reflected on a mineral’s surface. It is one of the properties that mineralogists consider when determining the identity of a mineral. Metallic, glassy, pearly, silky, greasy, and dull are some common terms for lustre.
