Ch 23: OAE - Integrated Science: Physical Geology & Earth's History

About This Chapter

The OAE Integrated Science exam will have a series of questions on physical geology and the Earth's history. Review this subject with the help of our study guide. Our energetic instructors will make your studying fun and interesting.

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.

The Origin of Life on Earth: Theories and Explanations

1. The Origin of Life on Earth: Theories and Explanations

Scientific theories of the origin of life on Earth are varied and typically focused on the utilization of radiation and chemical compounds within the atmosphere of the planet. Learn about the early stages of life on Earth from a scientific perspective, and discover the explanations provided by the Oparin Hypothesis and the Miller-Urey experiment.

The History of Life on Earth: Timeline and Characteristics of Major Eras

2. The History of Life on Earth: Timeline and Characteristics of Major Eras

Life on Earth started millions of years ago and these periods are classified into several major eras defined by the characteristics of the organisms existing within the appropriate timelines. Learn about the characteristics of different organisms that existed during major timelines in history.

The Four Spheres of Earth: Geosphere, Hydrosphere, Biosphere, and Atmosphere

3. The Four Spheres of Earth: Geosphere, Hydrosphere, Biosphere, and Atmosphere

The interconnected processes of planet Earth are described in four 'spheres': Geo (earth), Hydro (water), bio (life) and atmo (air). Learn the features of each, the processes that occur in their specific domain.

Major Plates of the Lithosphere: Earth's Tectonic Plates

4. Major Plates of the Lithosphere: Earth's Tectonic Plates

The lithosphere is the solid, outer part of the Earth and has seven major tectonic plates. Learn more about the lithosphere, plate tectonics, and the seven major tectonic plates.

Causes of Tectonic Plate Movement

5. Causes of Tectonic Plate Movement

Tectonic plates are huge moving pieces of the Earth's crust and there are different mechanisms that can explain the causes of their movement. Learn about the different forces and mechanisms involved in the plate movement process, including thermal convection, ridge push, slab pull, and trench suction.

Plate Boundaries: Convergent, Divergent, and Transform Boundaries

6. Plate Boundaries: Convergent, Divergent, and Transform Boundaries

The three types of plate boundaries are divergent, convergent, and transform boundaries. Explore these boundaries, the theory of plate tectonics, and how convection currents cause the Earth's plates to move.

What is Pangaea? - Theory & Definition

7. What is Pangaea? - Theory & Definition

The world's continents as we know them today were formed millions of years ago when Pangaea broke apart. Learn about the origin of the continents and understand what the theory of Pangaea entails. Explore the idea of supercontinents, review the continents of Pangaea, and recognize the evidence that supports continental drift theories.

Plate Tectonics: A Unified Theory for Change of the Earth's Surface

8. Plate Tectonics: A Unified Theory for Change of the Earth's Surface

Plate tectonics involve a unifying theory of how the surface of the earth changes. Explore this theory, what causes plates to move, and learn about the term lithosphere, asthenosphere, mantle, and core.

Alfred Wegener's Theory of Continental Drift

9. Alfred Wegener's Theory of Continental Drift

Alfred Wegener theorized the movement of continents, the theory of continental drift, by gathering evidence unexplained by the accepted model of his time. Explore how he studied coastlines, fossils, and geologic features to develop his theory and discover the challenges he faced.

Evidence for the Mechanism of Continental Drift

10. Evidence for the Mechanism of Continental Drift

Scientists discovered evidence for the mechanism of continual drift. Learn about the lithosphere, plates, and faults, and consider the evidence in support of the continental drift theory.

Ocean Drilling as Evidence for Plate Tectonics

11. Ocean Drilling as Evidence for Plate Tectonics

One of the ways that scientists study the ocean floor is through deep sea drilling projects, which began in the 1960s. Learn more about the first Deep Sea Drilling Project (DSDP) and how it led to more scientific discoveries about plate tectonics, the Mid-Atlantic Ridge and seafloor spreading.

Paleomagnetism and Hot Spots: Evidence for Plate Tectonics

12. Paleomagnetism and Hot Spots: Evidence for Plate Tectonics

Plate tectonics is a scientific theory used to explain how the Earth's surface, including the continents and oceans, has moved in the past as well as in the present. Explore plate tectonics and learn about paleomagnetism and hot spots, which provide evidence to support plate tectonics theory.

Sea Floor Spreading and Polar Reversal

13. Sea Floor Spreading and Polar Reversal

The discovery of the Mid-Ocean Ridge opened the door to understand sea floor spreading and polar reversal. Learn about how normal and reversed polarity that was discovered in stripes along the ocean floor allowed scientists to understand how the sea floor spreads.

The Processes of Mountain Building

14. The Processes of Mountain Building

There are a wide variety of mountain types, but not all mountains are built equally. Explore the different types of mountains--such as fold, dome, and fault-block mountains--and learn about the process in which mountains are created.

Earth's Internal Layers: Crust, Mantle & Core

15. Earth's Internal Layers: Crust, Mantle & Core

There are several distinct layers within the Earth. This lesson digs deeper into those layers, taking the reader on a journey of exploration from the core upward through the mantle to the crust.
