What minerals break along smooth flat surfaces?

Calcite has cleavage. It breaks along flat surfaces because the bonds between its atoms are less strong in some directions than in others.

Which mineral property explains why some minerals break along smooth flat surfaces?

The way in which a mineral breaks along smooth flat planes is called cleavage. These breaks occur along planes of weakness in the mineral’s structure.

When a mineral does not break along smooth flat surfaces this is called?

One reason gemstones are beautiful is that the cleavage planes make an attractive crystal shape with smooth faces. Fracture is a break in a mineral that is not along a cleavage plane. Fracture is not always the same in the same mineral because fracture is not determined by the structure of the mineral.

What occurs when minerals break unevenly along curved or irregular surfaces?

Fracture is the tendency of some minerals to break unevenly along curved or irregular surfaces.

What common mineral that breaks with rough or jagged edges?

Quartz
Quartz breaks unevenly along jagged edges because it has tightly bonded atoms.

What are mineral fractures?

fracture, in mineralogy, appearance of a surface broken in directions other than along cleavage planes. See also cleavage.

What property describes the sparkles of the mineral surfaces?

Luster
Luster is the relative differences in the opacity and transparency of a mineral as light is reflected on its surface. This describes the ‘sparkles’ of the mineral surfaces. The way that a mineral reflects light from its surface is called luster.

Why does Mica break in smooth flat surfaces?

The number and strength of bonds between the silica, aluminum, and hydroxide ions make those layers much stronger. Therefore, muscovite mica is much more likely to break along the layers that only contain the weakly bonded potassium ions. This results in 1 excellent cleavage plane of mica.

What is mineral breakage?

Definitions. Cleavage – The tendency of a mineral to break along flat planar surfaces as determined by the structure of its crystal lattice. These two-dimensional surfaces are known as cleavage planes and are caused by the alignment of weaker bonds between atoms in the crystal lattice.

When minerals break into pieces with jagged or rough edges or smooth and curvy edges it is called?

Which minerals have a fracture?

It often occurs in amorphous or fine-grained minerals such as flint, opal or obsidian, but may also occur in crystalline minerals such as quartz.

What is a mineral can be hammered flattened?

Malleable – If a mineral can be flattened by pounding with a hammer, it is malleable. All true metals are malleable. An example is Silver.
