Ch 6: Holt McDougal Earth Science Chapter 6 - The Rock and Fossil Record

About This Chapter

The Rock and Fossil Record chapter of this Holt McDougal Earth Science Online Textbook Help Course helps students learn essential earth science lessons on the rock and fossil record. Each of these simple and fun video lessons is about five minutes long and is sequenced to align with the Rock and Fossil Record textbook chapter.

How it works:

  • Identify the lessons in the Holt McDougal Rock and Fossil Record chapter with which you need help.
  • Find the corresponding video lessons with this companion course chapter.
  • Watch fun videos that cover the rock and fossil record topics you need to learn or review.
  • Complete the quizzes to test your understanding.
  • If you need additional help, rewatch the videos until you've mastered the material or submit a question for one of our instructors.

Students will learn:

  • Geological evolution theories
  • Paleontology and archaeology facts
  • Methods of geological dating
  • Relative dating concepts
  • Radiometric dating principles
  • Half-life significance
  • Fossil preservation conditions
  • Relative dating using fossils
  • Geologic time scale

Theories of Geological Evolution: Catastrophism vs Uniformitarianism

1. 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.

What Are Paleontology & Archaeology? - Definition, History & Facts

2. What Are Paleontology & Archaeology? - Definition, History & Facts

While they do have similarities, paleontology and archaeology are two fields with different goals. In this lesson, you'll learn about these unique sciences, as well as some of the sub-disciplines that fall under each.

Methods of Geological Dating: Numerical and Relative Dating

3. 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

4. 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

5. 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

6. 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.

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

7. 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!

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.

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

9. 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.
