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 a record of the planet's history told through layers in rocks, known as strata. Discover the use of strata in the concept of timeline divisions and learn about eons, eras, periods, and epochs.
2. Theories of Geological Evolution: Catastrophism vs Uniformitarianism
Catastrophism, a theory of the Earth's development posited by the naturalist Georges Cuvier, proposed that Earth's history was the result of frequent geological catastrophes. Later, the geologist James Hutton proposed instead that the Earth was formed by gradual change over long periods of time, a theory called uniformitarianism. Explore the origins of these two geological theories, and how they affected our modern understanding of the Earth.
3. Methods of Geological Dating: Numerical and Relative Dating
Scientists use a combination of relative and numerical dating to establish the age of rocks and fossils. Explore these two methods and learn how each one works.
4. What is Relative Dating? - Law of Superposition, Principles of Original Horizontality & Cross-Cutting Relationships
Unlike its cousin numerical dating, relative dating cannot identify the actual age of a rock, but it can determine if a rock is older or younger than another rock. Explore the nuances of relative dating, and discover related concepts, such as the principle of original horizontality, the law of superposition, cross-cutting relationships, inclusions, and uniformities.
5. Principles of Radiometric Dating
Radiometric dating is a process used to determine the age of the Earth's rocks and other geological materials, such as carbon. Learn about the principles of radiometric dating and understand its processes by studying radioactive decay, parent and daughter nuclides, and types of decay.
6. Radiometric Dating: Methods, Uses & the Significance of Half-Life
Scientists use a process called radiometric dating to help determine the age of rocks and other objects. This lesson explains that process, defines important terms such as half-life, and investigates some of the different methods of radiometric dating.
7. Conditions of Fossil Preservation: Rapid Burial, Hard Parts & the Elements
Fossil preservation occurs when the minerals in an organism's remains turn to rock or leave an imprint in sedimentary stone. Learn how rapid burial, the organism's hard parts, and the elements contributed to the conditions necessary for the fossil preservation of prehistoric life.
