Ch 7: OAE Earth & Space Science: Historical Geology

About This Chapter

Passing the OAE Earth and Space Science examination will require your knowledge of topics related to historical geology. Discover what subjects you remember and what you need to review when you watch this chapter's online video lessons.

OAE Earth and Space Science - Historical Geology - Chapter Summary

Prepare to take the OAE Earth and Space Science examination. The video lessons in this chapter will allow you to reflect on historical geology and evolution. Recall explanations about the effects of photosynthesis on early Earth and re-examine some theories and hypotheses about our planet's origins. Other covered topics include the ozone layer, uniformitarianism, and geological and radiometric dating. Review this chapter's video lessons for help with:

  • Exploring the geologic time scale
  • Discussing theories about the stages of life and the atmosphere on ancient Earth
  • Understanding the theories of geological evolution
  • Explaining the law of superposition along with numerical and relative dating methods
  • Describing how index fossils are used to indicate the age of a rock
  • Discussing three kinds of radioactive decay
  • Learning more about fossil preservation

In addition to being led by professional educators, the brief video lessons are self-paced so that you can fit study time into your schedule. You may submit questions about historical geology, use the video tags to search for information and read over the written transcripts as you get ready to take the OAE Earth and Space Science examination. There are also self-assessment quizzes and a multiple-choice practice chapter examination to test your retention of the above subjects.

OAE Earth and Space Science - Historical Geology Objectives

The second domain of the five-part OAE Earth and Space Science examination is titled 'Geology.' It is during this section that you'll demonstrate your knowledge of the Earth's ancient history and other scientific topics as you work toward earning a science teaching endorsement. This domain accounts for 25% of the assessment score. There are 150 multiple-choice questions on the OAE Earth and Space Science examination. You'll have 180 minutes to complete the computer-administered assessment.

Geologic Time Scale: Major Eons, Eras, Periods and Epochs

1. Geologic Time Scale: Major Eons, Eras, Periods and Epochs

The geologic time scale is an essential tool for understanding the history of Earth and the evolution of life. In this lesson, explore the principal eons, eras, periods, and epochs that help us track major events in geologic history.

The Origin of Life on Earth: Theories and Explanations

2. The Origin of Life on Earth: Theories and Explanations

Ever wonder how living things came from non-living things? We will explore what conditions on early Earth may have created life from non-living items.

The Atmosphere on Earth

3. The Atmosphere on Earth

This lesson describes the evolution of the Earth's atmosphere, from its ancient past to the present day to how it's being changed by humans today. You'll learn about how outgassing, photosynthesis, and oceans all played a role in its formation, what air is composed of, and the real effect of human pollution on our changing atmosphere.

The Development of Earth's Hydrosphere

4. The Development of Earth's Hydrosphere

What is Earth's hydrosphere? And where did all that water come from? Learn how scientists answer these questions, and then take a quiz to test your knowledge.

Theories of Geological Evolution: Catastrophism vs Uniformitarianism

5. Theories of Geological Evolution: Catastrophism vs Uniformitarianism

Geologists haven't always agreed about the history of our planet. They have debated between catastrophism and uniformitarianism over the last few hundred years! Learn about the two main theories of geologic evolution and how scientists came to resolve the dispute.

Methods of Geological Dating: Numerical and Relative Dating

6. Methods of Geological Dating: Numerical and Relative Dating

Learn how scientists determine the ages of rocks and fossils. We'll explore both relative and numerical dating on our quest to understand the process of geological dating. Along the way, we'll learn how stratigraphic succession and radioactive decay contribute to the work of paleontologists.

What is Relative Dating? - Law of Superposition, Principles of Original Horizontality & Cross-Cutting Relationships

7. What is Relative Dating? - Law of Superposition, Principles of Original Horizontality & Cross-Cutting Relationships

Discover how geologists study the layers in sedimentary rock to establish relative age. Learn how inclusions and unconformities can tell us stories about the geologic past. We'll even visit the Grand Canyon to solve the mystery of the Great Unconformity!

Relative Dating with Fossils: Index Fossils as Indicators of Time

8. Relative Dating with Fossils: Index Fossils as Indicators of Time

You may already know how to date a fossil with a rock. But did you know that we can also date a rock with a fossil? Watch this video to find out how we use index fossils to establish the relative ages of rocks.

Principles of Radiometric Dating

9. Principles of Radiometric Dating

Radiometric dating is a method used to determine the age of rocks and other materials based on the rate of radioactive decay. Learn about three common types of radioactive decay: alpha decay, beta decay and gamma decay.

Conditions of Fossil Preservation: Rapid Burial, Hard Parts & the Elements

10. Conditions of Fossil Preservation: Rapid Burial, Hard Parts & the Elements

Learn how fossils are formed and how varying conditions affect the preservation of organisms. What is the best way for a dinosaur to become fossilized? Find out here!
