Minerals and Their Properties
Grade 6 · Science · Earth Processes · Utah, USA
Lesson Summary
Minerals are naturally occurring solids with a crystal structure, and they can be identified by properties like hardness, color, and luster.
Explanation
A mineral is a naturally occurring, inorganic solid with a specific chemical formula and crystal structure. Scientists identify minerals by testing their properties: hardness (how easily it scratches), luster (how it reflects light), color, streak (the color of its powder), and cleavage or fracture (how it breaks). The Mohs hardness scale ranks minerals from 1 (talc, very soft) to 10 (diamond, very hard). Minerals are the building blocks of rocks and are used in everything from electronics to construction.
Practice Questions
Q1: Name three properties used to identify minerals.

Q2: What is the hardest mineral on the Mohs scale?
Answer: Diamond, with a hardness of 10.
Q3: What is the difference between a mineral and a rock?
Answer: A mineral is a single substance with a specific chemical formula, while a rock is made of one or more minerals combined together.
