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. Crystal: Definition, Types, Structure & Properties
This lesson is on crystals. Here, we'll review what the four types of crystals are and the different physical structures possible. We will also go over the properties of the different types of crystals and give examples.
11. What is a Diamond? - Definition, Types & Properties
Diamonds are forever, right? Have you ever wondered from what those shiny, long-lasting jewels were made? At first glance, you might think glass, but in this lesson, we will discover that diamond is made from something you might never expect.
12. What is Sulfate? - Definition, Structure & Formula
From drinking water to those rain showers on a cloudy day, sulfate is abundant in our environment. In this lesson, we'll explore more about this compound, its structure and formula.
13. Common Minerals & Their Uses
Minerals are used in everything from batteries to clocks. After completing this lesson, you'll have a better understanding of some common minerals and their uses in everyday life.
14. What is Dolomite? - Definition, Structure & Uses
Dolomite is a mineral that you may not have heard of, but it is still an important part of your life. Check out this lesson to learn about the structure, properties, and uses of this interesting natural resource.
