Halite and Calcite. Halite has what is known as cubiccleavage, where there is cleavage in three directions at 90 degree angles. Calcite has what is known as rhombohedral cleavage, where there is cleavage in three directions but at 120 and 60 degree angles.

Examples of minerals with perfect cleavage are calcite, biotite and mica.

Why do some minerals break by fracturing?
Minerals can have a cleavage plane, multiple cleavage planes, or no cleavage plane. A cleavage plane is an area of weakness in the crystalline structure where the mineral is prone to splitting.
What is the physical property denoting a minerals tendency to crack along parallel planar surfaces?
cleavage. cleavage.
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.
Do all minerals have cleavage?
Yes,Halite has cubic cleavage. This means it can break along planes in three directions.
A mineral that has uneven surfaces when broken is said to have?
That is referred to as fracturing.
What are two types of minerals that have cleavage?
mica and something else
Which two minerals have cleavage planes at right angles?
halite and pyroxene
Which two minerals have cleavage planes right angles?
halite and pyroxene
Does a mineral have crystal form but no cleavage?
All minerals have a crystal form, but not all have cleavage.
What should you do if two rocks contain yellow minerals but you know they are different minerals?
You can look at the streak, specific gravity, and if it have cleavage or not.
What 2 ways can minerals break?
Minerals break in the main two ways cleavage and fracture. Cleavage is breaking in flat planes but fracture is more uneven even unpredictable. The hardest mineral to break would be the diamond, which is placed at a ten on Moh's hardness scale.
What minerals have only one direction of cleavage?
Mica minerals have only one direction of cleavage. Examples are Muscovite and Biotite.
What type of minerals have cleavage?
all different types of minerals
How is cleavage related to atomic structure?
Cleavage is related to the minerals atomic structure because minerals are arranged in crystal lattices . It's the shape of these lattices that determine the mineral's cleavage.
What is the cleavage of bauxite?
Because bauxite is a rock, a mixture of minerals, it has no cleavage of its own.
What is the tendency of minerals to break?
Cleavage
How is cleavage related to a mineral's atomic structure?
Cleavage is related to the minerals atomic structure because minerals are arranged in crystal lattices . It's the shape of these lattices that determine the mineral's cleavage.
