rock and mineral Flashcards
mineral
a mineral or mineral species is, broadly speaking, a solid chemical compound with a fairly well-defined chemical composition and a specific crystal structure that occurs naturally in pure form.
rock
rock, in geology, naturally occurring and coherent aggregate of one or more minerals. Such aggregates constitute the basic unit of which the solid Earth is composed and typically form recognizable and mappable volumes.
Element
an element is a pure substance consisting only of atoms that all have the same numbers of protons in their nuclei.
Compound
A chemical compound is a chemical substance composed of many identical molecules composed of atoms from more than one element held together by chemical bonds.
Crystal

A crystal or crystalline solid is a solid material whose constituents
Color
Color is the aspect of things that is caused by differing qualities of light being reflected or emitted by them.
Luster
Luster or luster is the way light interacts with the surface of a crystal, rock, or mineral. The word traces its origins back to the Latin lux, meaning “light”, and generally implies radiance, gloss, or brilliance. A range of terms are used to describe luster, such as earthy, metallic, greasy, and silky.
Streak
Streak is an American software company which is the developer of an eponymous customer relationship management platform for Gmail.
Cleavage

These flat breaks are termed “cleavage.” The classic example of cleavage is mica, which cleaves in a single direction along the basal pinnacle, making the layers seem like pages in a book. In fact mineralogists often refer to “books of mica.
Fracture
Causes of bone fractures include trauma, overuse, and diseases that weaken bones.
The main symptom is pain. There may also be loss of functionality depending on the area affected.
Density
Density is the mass per unit volume of any object. It is calculated by dividing the mass of an object by its volume. The volume of objects can be worked out by multiplying height by length by width.
Ore
Ore is natural rock or sediment that contains one or more valuable minerals, typically containing metals, that can be mined, treated and sold at a profit.
Metallic minerals
These deposits can consist of a variety of metallic minerals containing valuable metals such as nickel
Non-metallic minerals
Nonmetallic minerals are, for example, sand, gravel, limestone, clay, and marble. Such materials lack metallic characteristics like good electric and thermic conductivity, luster, rigor, and malleability; they are, however, essential for many industries.
Gemstones
A gemstone is a piece of mineral crystal which, in cut and polished form, is used to make jewelry or other adornments. However, certain rocks and occasionally organic materials that are not minerals are also used for jewelry and are therefore often considered to be gemstones as well.
