In this chapter, you'll learn the answers to questions including:
- What are the optical properties of minerals?
- What does the crystal habit mean in relation to minerals?
- What terms are used to describe mineral strength?
- How do silicate and non-silicate minerals differ?
- How do rocks and minerals differ?
- What are the three basic groups of rocks?
1. Optical Properties of Minerals: Luster, Light Transmission, Color & Streak
Minerals are conveniently identified based on their physical properties. These properties include luster, ability to transmit light, color and streak. This lesson will describe each of these properties and examples of each.
2. Crystal Shape of Minerals: Forms and Types
Did you know that the term crystal can have different meanings in addition to something pretty to look at? A crystal can refer to a regular pattern of molecules within a mineral or the shapes at a macroscopic level. This is also known as the crystal habit.
3. Mineral Strength: Tenacity, Hardness, Cleavage & Fracture
What does it mean to say that one mineral is stronger than another? This lesson will explore different minerals to identify and describe mineral strength in terms of tenacity, hardness, cleavage and fracture.
4. Mineral Density & Specific Gravity: Definition and Properties
Mineral density and specific gravity are similar properties used by mineralologists to identify minerals. This lesson describes a common practice used to determine density and specific gravity.
5. Silicate Minerals: Chemical Classifications & Examples
Silicate minerals make up the bulk of the earth's crust. All silicates are made of the same building block, the silicon-oxygen tetrahedron. This lesson describes the major silicate minerals including feldspars and quartz.
6. Non-silicate Minerals: Chemical Classifications & Examples
While most minerals are silicates, many non-silicate minerals are found in the earth's crust and are important as well. This lesson will use examples and describe the three major groups of non-silicate minerals, including carbonates, halides and sulfates.
7. Rocks and Minerals: Definitions and Differences
Can you tell the difference between a rock and a mineral? What makes a mineral so much different from a rock? Explore these questions in depth, and learn how we classify rocks and minerals.
8. Rock Cycle: Igneous, Sedimentary, and Metamorphic Rocks
In this lesson, we will discuss the three main types of rocks and how they are formed. The lesson also gives an introduction into how matter locked in rocks can be cycled through the earth.
9. Types of Rocks: The Three Major Rock Groups
Did you know that lava is molten rock that reaches the earth's surface? Furthermore, did you know that rocks exist in three general forms: igneous, sedimentary and metamorphic? This lesson describes these rock types and examples of each.
10. Mafic: Definition & Composition
Mafic is a term used by geologists to describe igneous rocks and minerals. This lesson will examine the definition of this term and how to relates to earth processes.
11. What is a Gem? - Definition, Types & Properties
Explore the beautiful and fascinating world of gems. Learn about their properties, classification methods, and what makes them unique from other types of rocks and minerals.
12. Leaching: Definition & Process
From its commercial applications to the environmental concerns surrounding it, leaching is a very well known chemical process. Discover what leaching is and how this process works. Then test your knowledge with a short quiz.
13. Aluminum Hydroxide: Formula & Side Effects
Have you ever had really bad heartburn or a sour stomach? If so, aluminum hydroxide can be used to treat it. Continue reading to learn about aluminum hydroxide and its formula. Understand the side effects from taking medications containing this compound.
14. What is Dolomitization? - Formation, Origin & Formula
What is dolomitization and how does it happen? In this lesson, you'll learn about the process of dolomitization, including how it's formed, its origins, and much more.
15. Soil Contamination: Treatment, Phytoremediation & Bioremediation
Soil is often contaminated with various pollutants such as petroleum products, heavy metals, pesticides and other toxins. This lesson is about the treatment of contaminated soil using bioremediation and phytoremediation.
16. Soil Contamination: Definition, Sources & Prevention
This lesson defines soil contamination and its important components. Then you'll learn about the numerous types and sources of contamination as well as ways by which soil contamination can be prevented.
