1 like•606 views
Rocks are solid materials that make up the Earth's surface, composed of one or more minerals. Minerals are natural solids formed in the Earth's crust that are not composed of other minerals. There are over 3,000 known minerals on Earth but rocks are composed of less than 20 common minerals. Key differences are that rocks can have multiple colors while minerals have one color and minerals are shinier than rocks. Examples of rocks include limestone, marble and diorite while minerals include gold, diamond and silver.

1. Rocks are made up of minerals and can be found deep underground in mines or near the surface in quarries.
2. Minerals have unique properties like hardness, lustre, and color that allow them to be identified. They are used to make construction materials, obtain metals, and create jewelry.
3. Soil is formed over long periods of time as rocks are broken down by weathering and mixed with decaying matter. It is made up of layers with different materials and must be protected to support plant growth.
Properties of minerals
Minerals are naturally occurring inorganic solids with a crystal structure and definite chemical composition. They have specific identifying properties including hardness, color, streak, luster, and density. Minerals must be naturally occurring on Earth, inorganic, solid, and have a crystal structure with definite proportions of elements in their chemical composition.
Minerals
Rocks are natural solids made of one or more minerals or mineraloids. Minerals are naturally occurring crystalline chemical compounds not produced by living things. This document lists rocks and minerals, including gold, silver, and provides links for more information about minerals and polished stones.
Minerals - Identifying Minerals
Minerals can be identified through various physical properties including color, streak, hardness, luster, cleavage, fracture, specific gravity, magnetism, acid testing, smell, taste, double refraction, and fluorescence. Some key properties include hardness measured on Mohs scale, metallic or non-metallic luster, whether the mineral breaks along smooth planes of cleavage or irregularly fractures, and comparing the mineral's weight to an equal volume of water to determine specific gravity. Identifying the combination of physical characteristics can help determine what mineral one has.
Minerals
The document discusses the properties of rocks and minerals. It defines a mineral as having a definite chemical composition and naturally occurring inorganic formation. It notes that the two most abundant elements in the Earth's crust are silicon and oxygen, which combine to form silicate compounds. Minerals can be identified based on properties like crystal structure, color, streak, luster, hardness, cleavage, and fracture.
Rocks and Minerals
Rocks and minerals are found almost everywhere on Earth and in everyday objects. Minerals are natural solid elements or combinations of elements that make up rocks. There are many types of minerals including metallic minerals like gold and silver and non-metallic minerals like salt and sand. Rocks and minerals are used to make many things in our lives from houses and cars to pencils and computers. They are essential building blocks of modern civilization.
Minerals
Minerals are naturally occurring, crystalline solids that are nonliving. They are divided into two main groups: silicates and non-silicates. Silicates make up about 90% of minerals and contain silicon and oxygen, while non-silicates do not contain these elements. Common silicate minerals include quartz, mica, feldspar and olivine, and non-silicates include native elements, carbonates, halides, oxides, sulfates and sulfides.

Earth Science: Identify minerals
A mineral is a natural solid substance that was never living. Minerals can be identified by their unique properties, including color, streak, luster, cleavage or fracture pattern, and hardness. Key properties include a mineral's color, the powder color when rubbed called its streak, how it reflects light for its luster, whether it breaks into smooth flat sheets or irregular pieces, and its hardness rating on the Mohs scale.
Characteristics of minerals
Minerals have five key characteristics that determine if a rock is classified as a mineral: 1) they are solid, 2) they are formed through inorganic processes, 3) they occur naturally, 4) they have a definite chemical composition, and 5) they have a definite crystalline structure. For a rock to be considered a mineral, it must meet at least three of these five characteristics, as some minerals do not exhibit all characteristics.
Minerals - What are they?
Minerals are naturally occurring inorganic solids with a definite crystalline structure and chemical composition. They are made up of elements and compounds that combine in different ways to form various minerals. Minerals then combine to form rocks. There are over 4000 known mineral species on Earth that each have unique physical and chemical properties determined by their composition and crystalline structure.

Minerals
Rocks and Minerals
A mineral is a naturally occurring inorganic compound with a unique chemical structure and physical properties.
A rock is a solid, stony mass composed of a combination of minerals or other organic compounds.
For example, quartz and feldspars are minerals, but when formed together, they make a rock, granite”
To determine if an Earth rock is a mineral, it should exhibit the following characteristics
Naturally occurring
Inorganic
Can be represented by a chemical formula
Crystalline structure
Solid
Most minerals form by inorganic processes but some, identical in all respects to inorganically formed minerals, are produced by organic processes
Transparency describes how well light passes through a mineral sample
There are three degrees of transparency: transparent, translucent, and opaque.
Habit of a mineral may be define as the size and shape of the crystal, and the structure of form shown by the crystal.
1. Accicular minerals showing needle like crystal. E.g. natrolite
2. Fibrous minerals showing an aggregate of long thin fibers. E.g. Asbestos
3. Tabular minerals showing bladed habit occur as small knife blades. E.g. Kyanite
4. Granular minerals which occur as aggregate of equidimensional grains. E.g. chromites
5. Pisolitic minerals which occur as aggregate of rounded grains of a pea size. E.g. oolite
6. Columnar minerals showing columnar crystal. E.g. tourmaline
Minerals strength determines how easy the mineral breaks or deforms when exposed to stress.
Reaction with Acid. Some minerals, especially carbonate minerals, react visibly with acid. (Usually, a dilute hydrochloric acid [HCl] is used.)
When a drop of dilute hydrochloric acid is placed on calcite, it readily bubbles or effervesces, releasing carbon dioxide
Minerals lecture grade 7
This document discusses minerals, their composition, properties, and classification. It states that minerals are naturally occurring inorganic solids with a definite chemical composition and crystalline structure. Most minerals are compounds made up of two or more elements, with oxygen and silicon being the most common. Minerals are classified based on their chemical structure and physical properties such as hardness, crystal structure, cleavage, fracture characteristics, luster, color, streak, fluorescence, and reaction to acid. The properties of minerals provide information about their internal atomic structure and composition.
8. rocks & minerals
Granite is an igneous rock composed of quartz, feldspar, mica, and usually hornblende. These minerals slowly crystallized as magma cooled below Earth's surface. Rocks are made up of minerals, which are natural solids composed of elements like oxygen and silicon bonded together. The character of a rock depends on the atomic structures and bonding of its minerals. Atoms are the basic building blocks of elements and can bond through ionic or covalent bonds to form minerals, rocks, and the continuous rock cycle.
Sedimentary rocks
This document provides information on the physical properties and occurrence of various sedimentary rock types. It describes the chemical composition, mineral composition, and locations where shale, sandstone, limestone, breccia, dolomite, conglomerate, greywacke, agate, travertine, flint, chert, coal, marlstone, jaspillite, sylvinite, taconite, mudstone, coquina, and halite are commonly found worldwide. The document is intended as a reference for students studying engineering geology and the characteristics of major sedimentary rocks.
Chapter 5 minerals
This document provides information about minerals, including their formation, composition, properties, and crystal structures. It discusses how minerals are the building blocks of rocks and are made up of arrangements of atoms. There are over 2,500 known mineral types that are classified based on their chemical composition and crystalline structure. Common properties described for identifying minerals include color, streak, luster, hardness, cleavage, and crystal shape.
Minerals
The document provides information about minerals, including their classification and identification. It defines what qualifies something as a mineral and lists the five criteria. Key points include: minerals have distinct chemical compositions and physical structures; they are classified based on their chemical makeup and crystal structure; silicate minerals are the most common and are made of silica tetrahedrons; physical properties like habit, luster, cleavage, hardness, color, and streak are used to identify unknown minerals. Mafic and felsic silicates are contrasted and different silicate mineral structures are described. Common non-silicate minerals are also named.
Minerals
This document discusses minerals and their properties. It notes that only a few minerals occur naturally as pure elements, while most are found as chemical compounds. Rocks are mixtures of minerals and elements. It then discusses various mineral properties like color, hardness, cleavage, specific gravity, and crystals. Key minerals mentioned include gold, silver, copper, quartz, calcite, and beryl. It also discusses ores, which are rocks containing valuable minerals, giving examples like hematite, malachite, and galena.
Minerals and rocks
Minerals and rocks are natural, non-living materials. Minerals are the building blocks of rocks and give rocks their properties. There are three main types of rocks: igneous, sedimentary, and metamorphic. Igneous rocks form from cooled lava or magma underground or at the Earth's surface. Sedimentary rocks form from compressed and cemented sediments over millions of years. Metamorphic rocks were originally igneous or sedimentary rocks that were changed by heat and pressure within the Earth.
the different Rock forming minerals
This document discusses rock-forming minerals and mineral resources. It defines minerals as naturally occurring inorganic solids with crystalline structures and fixed or varying chemical compositions. Minerals are the building blocks of rocks and undergo geological processes to form rocks. Some rocks contain useful mineral resources like metals that are extracted. Metallic mineral resources include ferrous minerals like iron ore and non-ferrous minerals like gold and copper. Non-metallic mineral resources like coal, clay and salt are associated with sedimentary rocks. Examples of common rock-forming minerals discussed are quartz, pyrite and talc.
Mineral identification
The document discusses how mineral identification can be done using various properties. It outlines several key properties including hardness, color, streak, luster, density, cleavage, fracture, chemical activity, and special properties. Minerals can be identified by comparing these observable properties to known mineral samples. The properties allow minerals to be distinguished from one another.
