About This Chapter
CEOE Earth Science: Rocks & Minerals - Chapter Summary
Studying for the CEOE Earth Science test might require you to revisit concepts you haven't explored in weeks, months or years. To make sure you're prepared to tackle rocks and minerals on the test, this chapter offers lessons that help you:
- Identify Earth's materials, including minerals, rocks, soil, metals and precious rocks
- Define and differentiate between rocks and minerals
- Explain the rock cycle and classification of igneous rocks
- Understand the differences between detrital and chemical sedimentary rocks
- Classify metamorphic rocks and describe the optical properties of minerals
- Describe different forms and types of crystal shapes
- Identify different methods used in identifying common rock-forming minerals
- List the chemical classifications of silicate and non-silicate minerals
You can review the lessons in any sequence that best suits your studies. The online delivery of these lessons allows you to review the videos on your smartphone, laptop or tablet. Ask instructors any questions you may have through the Dashboard.
CEOE Earth Science: Rocks & Minerals Chapter Objectives
The CEOE Earth Science test examines individuals' knowledge of earth science and ensures they're ready for the certification needed to teach the subject in Oklahoma classrooms. The topics in this chapter prepare you for questions from the geological systems subarea, which constitutes about 16% of the total test. All questions out of the respective subarea will have a multiple-choice format. You have 4 hours to take the test and must dedicate an additional 15 minutes to a computer-based test (CBT) tutorial. A score of 240 or higher is required to pass the test.
1. Earth's Materials: Minerals, Rocks, Soil & Water
Although the earth is a very complex system, there are only four main components of Earth that are the building blocks of life. These components are referred to as Earth's materials and include minerals, rocks, soil and water.
2. Other Earth Materials: Metals and Precious Rocks
Our planet contains a variety of natural resources that we rely on to survive. Some of these resources, including metals and precious rocks, are less common than others and serve unique functions.
3. 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.
4. 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.
5. 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.
6. Classification of Igneous Rocks: Textures and Composition
Igneous rocks can be classified by their texture and composition. Learn how texture is influenced by the cooling rate of magma and how different mineral compositions lead to different igneous rock classifications in this video lesson.
7. Detrital & Chemical Sedimentary Rocks: Definition & Differences
Detrital or clastic sedimentary rocks are composed of rock fragments. They are different than chemical sedimentary rocks, which are composed of mineral crystals. Learn how these sedimentary rocks differ in their formation and composition.
8. Classification of Metamorphic Rocks: Texture & Parent
Metamorphic rocks are classified by their texture, which is either foliated or non-foliated, and according to their parent rock. Learn about the different textures and parent rocks of metamorphic rocks.
9. 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.
10. 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.
11. 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.
12. 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.
13. Methods for Identifying Common Rock-Forming Minerals
Minerals are inorganic materials that make up rocks. This lesson will go through the various methods that are used to identify common rock-forming minerals.
