Ch 46: General Science: Rocks & Minerals

About This Chapter

Review the stages of the rock cycle, types of rocks and minerals and their properties as you study for NES General Science exam. This chapter consists of video lessons, text transcripts and short self-assessment quizzes.

AEPA General Science: Rocks & Minerals - Chapter Summary

Use the lessons of this chapter to improve your understanding of different types of rocks and minerals. Each lesson video is taught by an expert instructor and will help you in your preparation for questions on the National Evaluation Series (NES) General Science exam about:

  • Differences between rocks and minerals
  • The rock cycle and the three major rock groups
  • Optical properties of minerals
  • Types of mineral crystals
  • Strength and density of minerals
  • Difference between silicate minerals and non-silicate minerals

Use these animated lessons to learn all you can about rocks and minerals before the day of the big exam. The videos can be navigated with video tags, and they can be paused or moved forward with ease. When your schedule permits, study with the help of your computer, tablet or smartphone.

AEPA General Science: Rocks & Minerals Chapter Objectives

In the state of Arizona, the 150 multiple-choice questions of the NES General Science exam are administered to future science teachers to measure their understanding of the general sciences before they are awarded certification. On test day, you will be asked to complete these questions in three hours or less. The Earth and Space Science content domain of the exam accounts for 19% of the exam, and it may include some questions about rocks and minerals. Completing the lessons and assessments of the of chapter should prepare you for these questions.

Rocks and Minerals: Definitions and Differences

1. 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.

Rock Cycle: Igneous, Sedimentary, and Metamorphic Rocks

2. 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.

Types of Rocks: The Three Major Rock Groups

3. 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.

Optical Properties of Minerals: Luster, Light Transmission, Color & Streak

4. 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.

Crystal Shape of Minerals: Forms and Types

5. 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.

Mineral Strength: Tenacity, Hardness, Cleavage & Fracture

6. 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.

Mineral Density & Specific Gravity: Definition and Properties

7. 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.

Silicate Minerals: Chemical Classifications & Examples

8. 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.

Non-silicate Minerals: Chemical Classifications & Examples

9. 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.
