WebIf minerals break smoothly, along predetermined planes, the minerals are said to have cleavage. If a mineral does not have any degree of cleavage, it is said to have an irregular breakage pattern called fracture. Before starting the actual testing part of the activity, students should copy the cleavage chart into their notebook. WebWhat are the physical properties used to identify minerals group of answer choices?

WebIf the mineral has one or more good cleavages, they will be indicated by sets of similarly oriented planes called cleavage planes. The orientation of cleavage planes is determined by the crystal structure of a mineral and form preferentially through planes along which the weakest bonds lie, thus the orientation of cleavage planes can be used in optical … If a mineral has cleavage in three directions, then every side of the mineral has cleavage (i.e. length, width, and height). If a mineral occurs in modified crystals with more than six sides (i.e. an octahedron ) and exhibits cleavage on all the sides, than it has cleavage in " all directions ".
