About This Chapter
CEOE Earth Science: Geologic History - Chapter Summary
When studying for a certification test like the CEOE Earth Science exam, it's good to feel that you know what to expect. This chapter gives you insight into what you will see on exam day by exploring geologic history topics. Review the lessons to prepare for questions about:
- The geologic time scale and theories of geological evolution
- Interpreting events from natural phenomena
- Paleontological and stratigraphic information
- Geological, relative and radiometric dating
- Fossil preservation conditions
- The human fossil record
You can explore the lessons in any sequence, and visit them as often as needed until you feel that you fully comprehend the material. Use the Timeline to pinpoint key video segments that you'd like to revisit.
CEOE Earth Science: Geologic History Chapter Objectives
The CEOE Earth Science test needs to be taken in order to be certified to teach earth science classes in the state of Oklahoma. The test examines your knowledge across various subareas, including the foundations of scientific inquiry, space systems, atmospheric systems, geological systems and water systems. Topics in this chapter are found in the geological systems subarea, which constitutes about 16% of the total test.
The test consists of 80 selected-response questions and 1 constructed-response assignment. You can prepare for these questions by taking self-assessment quizzes in this chapter that are similar in terms of their format and content. A chapter exam also is available to aid you in your preparation.
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.
2. 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.
3. How to Interpret Events from Natural Phenomena
This lesson will explain what scientists can determine from looking at Earth's rock layers. It will cover terms used to describe parts within the layers of rock and how layers can change over time. Relative dating will also be discussed.
4. Analyzing Stratigraphic & Paleontological Information
There is a lot of information in the geological record, but how do we get it out? In this lesson, we will explore the concept of stratigraphy, and see how it can be used to study Earth's history.
5. 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.
6. 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!
7. 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.
8. 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.
9. 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!
10. Fossil Evidence for Biological Diversity, Speciation, & Mass Extinction
One of the best sources of evidence we have for evolution is the fossil record. Fossils provide a wealth of information on how species change over time and for exciting events like mass extinctions and new species formation.
11. The Human Fossil Record & Human Evolution
Fossils can help tell the story of how we evolved. This lesson sheds light on our closest relatives from the past and what traits human beings have developed over time. You'll learn about those species that are extinct but who live on in our genes.
