Which one is not true for minerals?
Solid: Liquids and gases are not considered minerals, in large part because their structure is constantly changing, which means they do not have a characteristic crystal structure. A true mineral must be solid.
Which of the following is true about a mineral?
To be classified as a “true” mineral, a substance must be a solid and have a crystal structure. It must also be an inorganic, naturally-occurring, homogeneous substance with a defined chemical composition. The chemical composition may vary between end members of a mineral system.

What is true about minerals quizlet?
The five characteristics necessary for a substance to be a mineral are Naturally Occurring, Inorganic, Solid, crystal structure and Definite Chemical Composition. … Each mineral has its own properties because all minerals are compounds. A mineral always contain certain elements in definite proportions.
What is not mineral?
Glasses such as obsidian, which are disordered solids, liquids (e.g., water, mercury), and gases (e.g., air) do not have a crystalline structure and are therefore not minerals.
Which of the following is true about a mineral compared to a rock?
A mineral is a naturally occurring inorganic element or compound having an orderly internal structure and characteristic chemical composition, crystal form, and physical properties. … A rock is an aggregate of one or more minerals, or a body of undifferentiated mineral matter.
Which of the following is not a class of minerals?
Which of the following is not the category of mineral? Solution: Precious metals are not minerals . Precious metals are rare, naturally occurring metallic chemical element of high economic value. Chemically, the precious metals tend to be less reactive than most elements.

What is true about the density of a mineral?
The density of a mineral is the ratio of its mass to its volume. It is a measure of how much “stuff” is squeezed into the amount of space the mineral occupies.
