When minerals do not display cleavage, they are said to have a fracture. Fracture describes the way a mineral breaks when it does not have cleavage planes. This can result in irregular or random patterns of breakage.
A mineral that splits evenly along flat surfaces is said to have a cleavage fracture. Cleavage occurs when a mineral breaks along weak atomic planes due to the internal atomic structure and bonding of the mineral.
This may be due to the overburden load, which is essentially the weight of all the material above the layer of minerals in question squashing them flat. Or it may be due to deformation caused by the movements of tectonic plates which often causes a form of deformation known as shearing where two things slide past each other. When this occurs in ductile rock masses, it acts to flatten and rotate mineral grains so that their long axis is parallel to the shear plane.
The parallel alignment of platy grains in a rock is called foliation. Foliation is commonly seen in metamorphic rocks where minerals align in a preferred orientation due to pressure and temperature changes during deformation.
Something that reflects the heat, like a mirror (something light or shiny) - materials that reflect a large proportion of the incident radiation are said to have a high albedo (or reflection coefficient).The material that has the highest specific heat (hydrogen)The material that is in thermal contact with cooler surroundings or that is not isolated from the surroundings)The material that has the most compact shape (a solid block will heat up slower than a thin sheet)

A material is considered ductile if it can be stretched or deformed without breaking. Ductility is the ability of a material to exhibit plastic deformation under tensile stress before fracture occurs. Materials like metals, such as gold and copper, are known for their ductile properties.

Two forces are said to be equivalent when they produce the same effect on an object, such as acceleration or deformation. This means that the forces have the same magnitude, direction, and line of action.
Fracture. When it breaks apart cleanly, that is called Cleavage.
