About This Chapter
OAE - Integrated Science: Physical Geology & Earth's History - Chapter Summary
This chapter will explore the history of Earth, from the origin of life to the development of our land masses. It will help you learn more about the theory of continental drift as well as the different layers of the earth in preparation for the OAE Integrated Science exam. Once you finish the chapter you will have reviewed:
- The origin of life on Earth and its history
- The geosphere, hydrosphere, biosphere, and atmosphere
- The lithosphere
- Tectonic plates and their movement
- Pangaea and plate boundaries
- Continental drift and its corresponding evidence
- Ocean drilling, paleomagnetism and sea-floor spreading
- Mountain-building processes
- The internal layers of the Earth
Watch each of our video lessons to review the important concepts you will be tested on. Our instructors will also provide some test taking tips. Then practice for your exam with our lesson quizzes. These quizzes are similar to what you will see on your test.
OAE - Integrated Science: Physical Geology & Earth's History Chapter Objectives
The computer-based OAE Integrated Science exam has four objectives: physical science, life science, earth and space science, and the nature of science. This chapter links to the earth and space science domain, which is worth about 19% of the score. The 3-hour exam has 150 multiple-choice questions.
1. The Origin of Life on Earth: Theories and Explanations
Ever wonder how living things came from non-living things? We will explore what conditions on early Earth may have created life from non-living items.
2. The History of Life on Earth: Timeline and Characteristics of Major Eras
The Earth is over 4.6 billion years old. Ever wonder what happened during certain time periods in that large amount of time? We will look at the major eons and eras of Earth's history along with important characteristics of each.
3. The Four Spheres of Earth: Geosphere, Hydrosphere, Biosphere, and Atmosphere
Earth is made up of four distinct yet connect spheres. In this video lesson, you will learn about where each sphere is found on Earth, as well as some features commonly found in each.
4. Major Plates of the Lithosphere: Earth's Tectonic Plates
The outer shell of the earth, the lithosphere, is broken up into tectonic plates. The seven major plates are the African plate, Antarctic plate, Eurasian plate, Indo-Australian plate, North American plate, Pacific plate and South American plate.
5. Causes of Tectonic Plate Movement
In this lesson, we explore the causes of plate movement, including thermal convection, ridge push and slab pull. Students will learn how these processes complement each other and form a theory for tectonic plate movement.
6. Plate Boundaries: Convergent, Divergent, and Transform Boundaries
In the theory of plate tectonics, the earth's crust is broken into plates that move around relative to each other. As a result of this movement, three types of plate boundaries are formed: divergent, convergent, and transform boundaries.
7. What is Pangaea? - Theory & Definition
The continents you know have existed for a long time, but not in their current locations. In fact, over 200 million years ago Pangaea broke apart by plate tectonic movement to form the continents we see today.
8. Plate Tectonics: A Unified Theory for Change of the Earth's Surface
After many years of trying to solve the mystery of the moving continents, enough data and evidence was collected to develop a unifying theory of how the surface of the earth changes. It's called plate tectonics.
9. Alfred Wegener's Theory of Continental Drift
People used to think that Earth was static, and that it never changed. Gradually, a body of evidence was gathered that made no sense in this model. Alfred Wegener, Geologic Supersleuth, laid the groundwork for a whole new theory for the large-scale changing nature of the earth.
10. Evidence for the Mechanism of Continental Drift
As scientists began to explore the ocean floor after World War II, they discovered many new clues to help them solve a mystery that had begun decades earlier - how the continents moved about on the surface of the earth.
11. Ocean Drilling as Evidence for Plate Tectonics
The Deep Sea Drilling Project extracted samples of the ocean floor that provided evidence to support the hypothesis of seafloor spreading and the theory of plate tectonics. Learn how these samples provided proof.
12. Paleomagnetism and Hot Spots: Evidence for Plate Tectonics
Paleomagnetism is the study of past magnetic fields. Hot spots are fixed pockets of heat that well up to form volcanic features. Learn how paleomagnetism and the study of hot spots provide evidence that supports the theory of plate tectonics.
13. Sea Floor Spreading and Polar Reversal
Sea floor spreading is the process by which new oceanic crust is formed by the upwelling of magma through diverging tectonic plates. Learn about the relationship between sea floor spreading and polar reversals detected on the ocean floor.
14. The Processes of Mountain Building
In this video lesson, you will learn about the process of mountain building. You will identify different ways that mountains form, as well as the different types of mountains that result from this process.
15. Earth's Internal Layers: Crust, Mantle & Core
Earth is made up of several different layers, each with unique properties. In this video lesson, you will identify each layer of Earth and how it relates to Earth as a whole.
