What property describes how a mineral breaks?
The property is referred to as cleavage or fracture, the tendency, or lack of tendency, of a mineral to break along planes of weakness. Some minerals have multiple planes of cleavage. Some have none, and are said to exhibit fracture.Cleavage is the tendency of a mineral to break along flat surfaces. The way in which a mineral breaks depends on how its atoms are bonded, or joined together. In a mineral that displays cleavage, the bonds of the crystal structure are weaker in the directions in which the mineral breaks.fracture is the tendency of a mineral to break into irregular pieces. Some minerals such as quartz break into pieces with curved surfaces. Other minerals may break differently-perhaps into splinters or into rough or jagged pieces. In a mineral that displays fracture, the bonds that join the atoms are fairly equal in strength in all directions. The mineral does not break along flat surfaces because there are no particular directions ofweakness in its crystal structure.
What role do chemical bonds play in minerals?
Chemical bonds are made to form each and every mineral.
What happens when a mineral splits apart easily along flat surfaces?
You could say it had plane cleavages. What happens is that bonds between the molecular planes are much weaker than those in the plane of the cleavage. Graphite and mica would be good examples.
Why do you need minerals?
They form bonds with certain proteins in your body. The best known is hemoglobin and iron in red blood cells.
How can a mineral be formed naturally?
All minerals are crystalline, and form by crystallization from a liquid medium. This may be molten rock or a solution in hot water. As these cool, atoms become locked in chemical bonds in a repeating pattern which is low in energy. This forms the repeating structure of a crystalline mineral.
Minerals may break across planes due to their atomic arrangements What is the term used for this type of break?
When minerals break along certain planes, it is known as cleavage. Typically, the pieces will be the same form and be bounded by smooth, flat surfaces. Cleavage is determined by the number of cleavage directions and the angle(s) between them.If the mineral breaks in an irregular, jagged or splintered edge, it is said to have a fracture.
Minerals that do not have weak bonds along specific planes will what?
Minerals that do not have weak bonds along specific planes will tend to have a higher resistance to breakage and fracturing. This is because weak bonds along specific planes create areas of weakness where the mineral is more likely to break or split. Without these weak bonds, the mineral will have a more cohesive structure and be less prone to breaking.
Tendency to break along smooth flat surfaces?
Many minerals have "cleavage" that causes them to split on flat cleavage planes. Such minerals include micas (muscovite, biotite. phlogopite), calcite, gypsum, and feldspars. Cleavage is the result of the minerals' crystal structure that has weaker chemical bonds aligned in planes.
When a mineral breaks along a weekly bonds plane it is called?
cleavage.
What does the presence of cleavage planes within a mineral tell you about the chemical bonds that hold a mineral together?
minerals with cleavage break along smooth, flat surfaces in one or more directions.
What determines whether a mineral will show cleavage or break irregular fractures?
It means that the chemical bonds of the mineral aren't too strong along the lines and that when you break the mineral it'll break along those lines. please go to www.freewebs.com/mccniu (minerals aren't on it)
Why do minerals cleave only in specific directions?
Cleavage depends on the arrangement and bonding of molecules. Minerals tend to split among the planes of weak bonds between their atoms. In specifying the cleavage properties of a mineral, scientists count the number of nonparallel planes of cleavage, and the angle between those cleavage planes.
Think critically what does the presence of cleavage planes within a mineral tell you about the chemical bonds that hold the mineral together?
It tells you that that mineral is smooth and flat ,and so are the chemical bonds. Because if it didn't it would be a fracture which means it is jagged and not smooth. I am sure of this answer because cleavage means physical property of some minerals that cause them to break along smooth, flat surfaces.

What is it called when a mineral breaks along weakly-bonded plane?
Cleavage is the tendency of materials to split along definite structural planes, yielding smooth surfaces. An example is shales or shists.
How a mineral breaks apart when it does not split evenly?
The two way by which minerals break are called cleavage and fracture. Cleavage is when a mineral breaks along a plane whose atomic bonds are weaker than in the rest of the mineral. Fracture is when a mineral is forced to be broken in an unnatural direction.
Having a weakness along a specific plane will allow a mineral to?
cleave
