High School Earth Science/Identification of Minerals High School Earth Science/Identification of Minerals - Hardness. 1  Hardness is a mineral's ability to resist being scratched. Minerals that are not easily scratched are hard. 2  As you can see, diamond is a 10 on Mohs Scale. Diamond is the hardest mineral, which means that no other mineral can scratch a diamond. Quartz is a 7, so it can be scratched by topaz, corundum, and diamond. Quartz will scratch minerals, such as fluorite, that have a lower number on the scale. Suppose you tested a piece of pure gold for hardness. Calcite would scratch the gold, but gypsum would not because gypsum is a 2 and calcite is a 3.

You fill one backpack with books so you can study later. 2  Density describes how much matter is in a certain amount of space. Substances that have more matter packed into a given space have higher densities.

- 1 A mineral is an element or chemical compound that is normally crystalline and that has been formed as a result of geological processes (Nickel, E. H., 1995).  2 Minerals are naturally-occurring inorganic substances with a definite and predictable chemical composition and physical properties.. ( 3 O' Donoghue, 1990).

Streak (mineralogy) Unlike the apparent color of a mineral, which for most minerals can vary considerably, the trail of finely ground powder generally has a more consistent characteristic color, and is thus an important diagnostic tool in mineral identification. If no streak seems to be made, the mineral's streak is said to be white or colorless. Streak is particularly important as a diagnostic for opaque and colored materials. It is less useful for silicate minerals, most of which have a white streak or are too hard to powder easily. The apparent color of a mineral can vary widely because of trace impurities or a disturbed macroscopic crystal structure.

- A mineral is a naturally occurring substance, representable by a chemical formula, that is usually solid and inorganic, and has a crystal structure.It is different from a rock, which can be an aggregate of minerals or non-minerals and does not have a specific chemical composition.inerals are not equivalent to rocks. A rock is either an aggregate of one or more minerals, or not composed of minerals at all. Rocks like limestone or quartzite are composed primarily of one mineral— calcite or aragonite in the case of limestone, and quartz in the latter case.

What are Minerals? Definite chemical composition means that all occurrences of that mineral have a chemical composition that varies within a specific limited range. For example: the mineral halite (known as  rock salt  when it is mined) has a chemical composition of NaCl.

Mineral A mineral is a naturally occurring substance, representable by a chemical formula, that is usually solid and inorganic, and has a crystal structure. It is different from a rock, which can be an aggregate of minerals or non-minerals and does not have a specific chemical composition.ommon distinguishing characteristics include crystal structure and habit, hardness, lustre, diaphaneity, colour, streak, tenacity, cleavage, fracture, parting, and specific gravity. More specific tests for minerals include magnetism, taste or smell, radioactivity and reaction to acid.

Mineral There have been several recent proposals to classify biogenic or amorphous substances as minerals. The formal definition of a mineral approved by the IMA in 1995: A mineral is an element or chemical compound that is normally crystalline and that has been formed as a result of geological processes.

What is the hardest nature substance? Pure diamond is the hardest known natural mineral substance and will scratch any other natural material. Diamond is therefore used to cut other diamonds; in particular, higher-grade diamonds are used to cut lower-grade diamonds. But after billions of bucks in research, times have moved on.

High School Earth Science/Identification of Minerals 1 You can identify a mineral by its appearance and other properties. 2  The color and luster describe the appearance of a mineral, and streak describes the color of the powdered mineral. 3  A mineral has a characteristic density. 4  Mohs hardness scale is used to compare the hardness of minerals.he scale lists common minerals in order of their relative hardness. You can use the minerals in the scale to test the hardness of an unknown mineral. As you can see, diamond is a 10 on Mohs Scale. Diamond is the hardest mineral, which means that no other mineral can scratch a diamond.

What Are Minerals? 1 Minerals Are Solid: substances that don't droop or melt or evaporate. 2  Minerals Are Inorganic: substances that aren't carbon compounds like those found in living things. 3  Minerals Are Crystalline: substances that have a distinct recipe and arrangement of atoms.rganic Minerals. The rule that minerals must be inorganic may be the strictest one. The substances that make up coal, for instance, are different kinds of hydrocarbon compounds derived from cell walls, wood, pollen and so on. These are called macerals instead of minerals (for more see Coal in a Nutshell).
