Objectives of the NES General Science: Historical Geology Chapter
Many states use the NES General Science assessment as a way to gauge the knowledge of educators seeking to secure or enhance their teaching certification or licensure. The exam is broken into four content domains that test your understanding of the nature of science, physical science, life science and earth and space science. Topics in this chapter are located in the earth and space science domain, which constitutes approximately 19% of the total test.
Simplify the process of studying for the exam by refreshing your knowledge of historical geology through the video lessons and video transcripts that feature helpful vocabulary words. Since the test is composed of all multiple-choice questions and is taken on computer, you can use the self-assessment quizzes in this chapter to test your knowledge of historical geology while giving yourself access to questions similar to the ones you'll see on the exam.
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. 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.
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!
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.
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.
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!
