What is the cleavage to barium?
Barium is an element which does not occur in pure (native) form on Earth. The two most common minerals in which barium occurs are Barite (BaSO4) and Witherite (BaCO3). According to its entry on wikipedia, Barite has Perfect cleavage parallel to base and prism faces: {001} Perfect, {210} Perfect, {010} Imperfect. I am unsure what sort of cleavage Witherite has.
What kind of faces are found in mineral crystals?
Mineral crystal faces of varying luster and geometric shapes.
What do atoms accumulate on during mineral growth?
crystal faces
What is a large mineral that is chrystal with brilliant color?
The sparkle is the reflection of light off the mineral crystal faces or cleavage surfaces.
What is a solid material with atoms arranged in a repeating pattern?
A crystal is a solid. But it is a solid with a natural geometrically regular form that has plane faces that are arranged symmetrically.
What is the difference between the crystal faces and cleavage faces?
cleavage surface are smooth and shiny as the fracture is due to weakness in the bonds between the atoms rather than a breakage. Crystal face is where the crystal development such as twinning take place.
Does a tetrahedron have parrallel faces?
No. The faces of a tetrahedron are equilateral triangles, but none of the faces is parallel to another one of the faces -- they could not be parallel, since by the definition of a tetrahedron, all the faces intersect(!) and parallel planes do not intersect.
Are Two planes parallel to a line parallel?
No. Consider two adjacent faces on a cuboid. Both planes are parallel to the edge at which the intersect. But the fact that they do intersect illustrates that they are not parallel.
What makes minerals sparkle?
The sparkle is the reflection of light off the mineral crystal faces or cleavage surfaces.
Can planes be parallel?
Yes. The opposite ends of any right prism consists of two congruent and parallel faces. Two planes are parallel if the vertical distance between them is always the same.
What are pairs parallel faces?
In a polyhedron - a 3-dimensional object - a pair of parallel faces are two faces which lie in planes that are parallel to each other.Parallel faces need not be congruent. For example, consider a pyramid whose top is sliced off by a plane parallel to it base. The flat top and the base will be parallel faces but will not be congruent.
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.
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.
How many parallel planes are in a triangular prism?
One pair because opposite cross-section faces are parallel to each other.
What is the break pattern of diamond?
Not sure what you mean by break pattern but diamond will cleave relatively easily with what is described as perfect cleavage in 4 directions. Which means it break relatively easily parallel to its crystal faces. Diamond cutters often take advantage of this property.
What geometric solids has two congruent circular faces and no vertices?
A sphere intersected by two parallel planes equidistant from its centre, An ellipsoid intersected by two parallel planes equidistant from its centre, A uniform hyperboloid intersected by two parallel planes equidistant from its centre, A torus with a wedge removed, A cylinder.
What has 2 identical circular faces and one more curved faces?
A doughnut with a [radial] slice cut out of it. A sphere sliced by two parallel planes.
