About This Chapter
OAE Earth and Space Science: Earth's Materials - Chapter Summary
Get ready for the OAE Earth and Space Science examination by brushing up on facts about the Earth's components. While watching this chapter's online video lessons, you could expand your knowledge of our planet's metals, precious rocks and inorganic minerals. More specifically, you could recall the differences between certain kinds of rocks and re-examine the ways in which rocks and minerals are classified. Review this chapter's videos in order to:
- Explore the composition of Earth's minerals, rocks, soil and water
- Compare Earth's ore and gemstones
- Discover how plant and animal life are sustained by Earth's materials
- Distinguish between rocks and minerals, and list the three main rock groups
- Discuss the texture, classification and composition of rocks as well as the differences between various kinds of rocks
- Understand the properties of minerals and the types of crystals
- Provide examples of silicate and non-silicate minerals
- Define soil and describe its composition
While you grow in knowledge of the Earth's materials, you'll increase your capacity to correctly answer related questions on the OAE Earth and Space Science examination. The video lessons are presented by subject experts whose conversational delivery make the review process fun and easy. You'll be able to choose when and where you study, and you can submit your questions about the Earth's materials to the instructors. Each of the lessons is followed by a self-assessment quiz.
OAE Earth and Space Science: Earth's Materials Objectives
Worth 25% of the overall assessment score, the Geology domain of the OAE Earth and Space Science examination includes questions about the Earth materials, structure and resources topics found in this chapter. The computer-administered examination lasts up to 180 minutes. It includes 150 multiple-choice questions.
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. How Earth Materials Sustain Animal and Plant Life
The earth can be a very complex system with many different interacting parts. But, at its base, it is made up of four main materials that make life on Earth possible for both plants and animals.
4. 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.
5. 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.
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. What is Soil? - Definition, Structure & Types
Soil is the material found on the surface of the earth that is composed of organic and inorganic material. Soil varies due to its structure and composition. Learn about the different types of soil and soil structures in this video lesson.
14. The Formation and Composition of Soil: Definition and Factors
In this video lesson you will learn how soil is formed and what it is made of. You will also learn about how soil is classified and distributed in layers underground.
