The identification of minerals
A naturally occurring, inorganic, solid with a crystal structure and a defined chemical composition
What is a mineral?
The processes by which atoms are arranged to form a material with a crystal structure.
What is crystallization?
A hard colorful mineral, that has a glassy luster.
What is a gemstone?
A valuable rock that contains metal or other minerals that can be mined and sold at a price.
What is an ore?
A process in which an ore is mixed with other substances then melted to separate the useful meters from the other elements the ore contains.
What is smelting?
Color, streak, luster, density, hardness, crystal systems, cleavedge, and fracture.
What are traits that identify minerals?
Magma, lava, evaporation, and hot water solutions
What are the four ways minerals form?
Minerals that are flattened into sheets, stretched into wire, hammered, or molded. They are used for many tools and machines.
What is a metal?
Looking for ore deposits. Many geologists map out ore deposits while doing this.
What is prospecting?
It makes the minerals pure and more useable. When the metals are separate they can be used for specific purposes.
What is the reason that smelting is done?
A scale used to measure hardness in a mineral.
What is Mohs hardness scale?
Underground it cools over years and years to form giant crystals
What is the way magma forms minerals?
Foods, medicines, fertilizers, and building materials.
What are some ways other minerals are used?
Strip mines, open mines, and shaft mines.
What are the three types of mines?
A small amount of carbon is added to make a stronger steel.
What is the processing done sometimes after smelting?
The color of a minerals powder.
What is a streak?
It erupts out of volcanoes, cools, and forms small crystals.
What is the way minerals form from lava?
They are beautiful and durable. They have a magnificent luster.
What is the reason people use gemstones in jewelery?
Shaft mines.
What is the type of mine that digs for minerals in veins?
A solid mixture of two or more elements, at least on of which is a metal. It is the result of adding carbon to minerals.
What is an alloy?
How light is reflected from a minerals surface
What is luster?
Minerals don't evaporate with a solution, or when hot water solutions cool.
What are the two ways minerals form a solution?
Give an explanation on which you think is better, gemstones or metals.
There is no correct answer.
Explain the type of mine you think is best, strip mines, open pit mines, or shaft mines.
There is no correct answer.
There can be alloys for specific purposes, so the right metal is used for the right purpose.
What is the reason for adding more minerals to alloys?
