What property causes the mineral galena to break into tiny cubes?
The property that causes galena to break into tiny cubes is its cleavage. Galena exhibits perfect cubic cleavage, meaning that when struck or broken, it tends to break along smooth, flat planes that are parallel to the cube faces of the crystal structure.
What makes minerals sparkle?
The sparkle in minerals is usually caused by their crystal structure and the way they interact with light. When light enters the crystal lattice of a mineral, it can be reflected and refracted, creating a sparkling effect due to the reflection and dispersion of light off the crystal faces. The presence of impurities or inclusions in the mineral can also contribute to its sparkle.
Why do halite crystals always break into smaller crystals of the same shape?
Halite crystals break into smaller crystals of the same shape due to the crystal structure and cleavage of the mineral. Halite has a cubic crystal structure and perfect cubic cleavage, which means it breaks along planes that are parallel to the faces of the cube, resulting in smaller crystals with the same cubic shape.
What is the cleavage of fluorite?
Fluorite has four perfect cleavage planes that are parallel to the faces of an octahedron. This results in the mineral breaking into octahedral fragments when cleaved.
What mineral property observer number and angle of crystal faces?
sorry i do not know
What are parallel lines seen on either cleavage planes or crystal faces?
Parallel lines seen on cleavage planes or crystal faces are usually caused by twinning, where two crystals grow together with a specific orientation relationship. This twinning can result in repeated patterns of parallel lines that are visible on the surface of the crystal.
What are the parallel lines seen on crystal faces or cleavage planes?
Parallel lines seen on crystal faces or cleavage planes are called growth striations. They are caused by variations in the crystal's growth rate or conditions during formation, resulting in alternating layers of different densities or compositions. These striations can provide valuable information about the crystal's growth history and conditions.
How rapidly does Quartz vibrate?
Quartz vibrates when a voltage is applied between opposite faces of a crystal. The frequency of the vibration depends on the thickness of the crystal, and on the direction of the faces compared to the natural planes in the crystal structure.

What are crystal facets?
the faces on a crystal...
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 difference between flat faces and sides?
Faces are sides but sides (as in sides of a square) need not be faces.
What are the flat sides of crystal called?
Faces
How do crystal systems differ?
In the angles between faces and the number of edges of equal length
What a the word for observe number and angle of crystal faces?
Crystal Systems is the word for "observe number and angle of crystal faces."
