Ch 48: CEOE Middle Level Science: Radiometric Dating

About This Chapter

We will help you prepare for your Certification Examinations for Oklahoma Educators (CEOE) for Middle Level Science. These video lessons discuss the topic of radiometric dating.

CEOE Middle Level Science: Radiometric Dating - Chapter Summary

Our subject matter experts take you through principles and methods used for dating events in Earth's history. Information covered in this review for the CEOE Middle Level Science exam includes:

  • Numerical and relative geological dating methods
  • Principle of original horizontality
  • Principle of cross-cutting relationships
  • Law of superposition
  • Principles of radiometric dating
  • Significance and uses of half-life

These short video lessons each have an accompanying transcript for you to use in following along. There is a short quiz at the end of each lesson, and if you have need to return to a section of the lesson… no problem. We include an easy-to-navigate timeline that is marked with keywords so you can go right to the spot that discusses the information you need. This study is fun, and, with our help, you will have nothing but nice things to say about your certification preparation experience.

Methods of Geological Dating: Numerical and Relative Dating

1. 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

2. 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!

Principles of Radiometric Dating

3. 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.

Radiometric Dating: Methods, Uses & the Significance of Half-Life

4. Radiometric Dating: Methods, Uses & the Significance of Half-Life

Radiometric dating is used to estimate the age of rocks and other objects based on the fixed decay rate of radioactive isotopes. Learn about half-life and how it is used in different dating methods, such as uranium-lead dating and radiocarbon dating, in this video lesson.
