what are the first two criteria for something to be a mineral? The first two criteria are; be formed from natural processes and to be an inorganic substance . This means it occurs naturally in earth and is not made up of living organisms.
What are the criteria of minerals?
Most minerals can be characterized and classified by their unique physical properties: hardness, luster, color, streak, specific gravity, cleavage, fracture, and tenacity .
What are the first three criteria for something to be a mineral?
Minerals can be identified by their characteristic physical properties. They include crystalline structure, hardness, density, breakage, and color .
What are the two of the five criteria for something to be a mineral?
Though minerals vary in shape, color, luster (the way a mineral reflects light) and hardness , all minerals are a solid at a given temperature.
What are the 2 main categories of minerals?
There are two kinds of minerals: macrominerals and trace minerals .
What are the 5 mineral requirements?
A mineral has 5 characteristics, naturally occurring, solid, inorganic, crystalline structure, and the same chemical composition throughout So repeat after me A mineral is Naturally occurring-naturally occurring Inorganic solid-inorganic solid Crystalline structure The same chemical composition throughout.
What 4 criteria must be met in order to be a mineral?
A mineral is an inorganic, crystalline solid. A mineral is formed through natural processes and has a definite chemical composition. Minerals can be identified by their characteristic physical properties, such as crystalline structure, hardness, density, breakage, and color .
What are examples of minerals?
Minerals are those elements on the earth and in foods that our bodies need to develop and function normally. Those essential for health include calcium, phosphorus, potassium, sodium, chloride, magnesium, iron, zinc, iodine, chromium, copper, fluoride, molybdenum, manganese, and selenium .
What are types of minerals?
- Native elements. eg. Gold, Silver, Mercury, graphite, diamond.
- Oxides. eg corundum (incl. sapphire), hematite, spinel.
- Hydroxides. eg. Goethite, brucite.
- Sulfides. eg. Pyrite, galena, sphalerite.

What are minerals Short answer?
Minerals are substances that are formed naturally in the Earth . Rocks are made of minerals. Minerals are usually solid, inorganic, have a crystal structure, and form naturally by geological processes.
Is rain water a mineral?
Rain water is relatively low in mineral content . In practice, people drink rainwater from streams and wells, where it has had ample opportunity to pick up minerals from soil and rock. Rain water contains very low amounts of salts and other nitrates but it takes in any gas present in air.
Is Salt a mineral?
Salt is a crystalline mineral made of two elements , sodium (Na) and chlorine (Cl). ... Most of the world’s salt is harvested from salt mines or by evaporating seawater and other mineral-rich waters. Salt has various purposes, the most common being to flavor foods.
What are the five characteristics of a rock?
Rocks are classified according to characteristics such as mineral and chemical composition, permeability, texture of the constituent particles, and particle size . These physical properties are the result of the processes that formed the rocks.
What are the 3 categories of minerals?
The major classes of minerals are: silicates . sulfides . carbonates .
What are the 7 classes of minerals?
The broadest divisions of the classification used in the present discussion are (1) native elements, (2) sulfides, (3) sulfosalts, (4) oxides and hydroxides, (5) halides, (6) carbonates, (7) nitrates , (8) borates, (9) sulfates, (10) phosphates, and (11) silicates.
What are the 13 essential minerals?
Minerals include calcium, phosphorus, sodium, potassium, magnesium, manganese, sulfur, chloride, iron, iodine, fluoride, zinc, copper, selenium, chromium and cobalt (which is part of the vitamin B12/cobalamine).
