Ch 16: OAE Earth & Space Science: Oceans

About This Chapter

Use this chapter's lessons to learn more about the world's oceans, including their depth and physical properties. Afterward, you can complete the chapter's self-assessment quizzes in preparation for taking the OAE Earth and Space Science examination.

OAE Earth and Space Science: Oceans - Chapter Summary

Although you may have previously studied various aspects of the planet's oceans, you might benefit from learning more about their formation and features. That's where this chapter's online video lessons can help. Review them prior to taking the OAE Earth and Space Science examination. As a result, you might be able to more clearly comprehend the effect of plate tectonics on ocean basins, identify different kinds of ocean waves and expand your overall knowledge of oceanography. Watch the videos so that you can:

  • Discuss theories on how the oceans were created
  • Learn more about the ocean's chemical properties and salt content
  • Define and describe different kinds of ocean basins
  • Explain how the oceanic ridge system was formed
  • Distinguish between passive and active continental margins
  • Describe the features of beaches and shorelines
  • Discuss the effects of ocean currents on the climate and discover how waves affect erosion
  • Examine the causes of tides as well as the factors that contribute to beach drift
  • Explore the effects of rising sea levels
  • Discover the focus of oceanographers

By watching the engaging video lessons in this chapter, you might refresh your memory of some topics and discover others for the first time. Well-educated instructors preside over the video lessons, which could prepare you to answer some of the questions on the OAE Earth and Space Science examination. The lessons include video tags that allow you to find information without delay. You may also consult the text transcripts, ask questions of the experts and take the self-assessment quizzes.

OAE Earth and Space Science: Oceans Chapter Objectives

Answer questions about the ocean when you get to the third domain of the five-domain OAE Earth and Space Science examination. Titled 'Oceanography and Freshwater Systems,' the section amounts to 19% of the whole assessment score. In order to earn a science teaching endorsement, you'll be required to pass this exam that includes 150 multiple-choice questions on the computer-based examination. In addition to a 15-minute tutorial, you'll have 180 minutes to answer all of the questions.

Theories About How Oceans Were Formed

1. Theories About How Oceans Were Formed

Today, more than 2/3 of Earth is covered with water, mostly in our oceans. But Earth itself is much older than our oceans. In this lesson you'll explore theories on how our oceans formed, as well as why liquid water remains on Earth even after all this time.

Properties of Ocean Water

2. Properties of Ocean Water

Ocean waters are salty and contain minerals and dissolved gases. They also have a high heat capacity and vary in density depending on temperature and salinity. Learn more about the unique chemical and physical properties of ocean water.

Ocean Basins: Definition, Formation, Features & Types

3. Ocean Basins: Definition, Formation, Features & Types

Ocean basins are those areas found under the sea. They can be relatively inactive areas where deposits of sediment slowly collect or active areas where tectonic plates meet. Learn how ocean basins form and about features such as oceanic ridges and trenches.

Oceanic Ridge System: Formation & Distribution

4. Oceanic Ridge System: Formation & Distribution

The oceanic ridge system is a continuous underwater mountain range with parts found in every ocean of the world. The ridge system is created when magma rising between diverging plates of the lithosphere cools and forms a new layer of crust.

Active & Passive Continental Margins

5. Active & Passive Continental Margins

Continental margins are areas that separate the continental crust and oceanic crust. Discover the differences between the tectonically active continental margins and the relatively quiet passive continental margins.

Characteristics of Shorelines & Beaches

6. Characteristics of Shorelines & Beaches

Shorelines and beaches are constantly changing due to forces, such as waves, winds and currents. Learn about characteristics of shorelines, including headlands, bays, beach berms, sand dunes, spits, tombolos, barrier islands and lagoons.

Ocean Circulation: Patterns & Effect on Climate

7. Ocean Circulation: Patterns & Effect on Climate

The ocean waters are always in motion and as they travel around the globe they carry and distribute heat, which affects the global climate. Learn about the ocean circulation patterns and how they impact the climate.

Waves: Types, Features & Effect on Erosion

8. Waves: Types, Features & Effect on Erosion

There are different types of ocean waves, including wind waves, tsunamis and tidal waves. Learn the features of waves and how their erosive effect creates the unique features found on the shoreline.

What Are Tides? - Causes & Effects

9. What Are Tides? - Causes & Effects

Tides rise and fall under the influence of the gravitational pull of the moon and sun. Learn about different tides, why they are predictable and their effects on coastal regions of the world.

Contributing Factors of Longshore Transport: Beach Drift & Longshore Current

10. Contributing Factors of Longshore Transport: Beach Drift & Longshore Current

The longshore transport is the process responsible for the movement of sand and sediment along the coastline. Sand and other particles are transported with the help of the longshore current and beach drift. Learn how these factors shape shorelines.

Changes in Sea Level: Causes & the Effect on the Environment

11. Changes in Sea Level: Causes & the Effect on the Environment

Sea level rise is a natural process, but recent trends are concerning because it is increasing at an alarming rate. In this lesson, you'll learn what causes changes in sea level and what effect rising sea level has on humans and the environment.

The Scientific Field of Oceanography

12. The Scientific Field of Oceanography

If studying oceans and their organisms sounds exciting to you, then you should consider a career in oceanography. Learn why this exciting field is so important to understanding other aspects of Earth, like the land and atmosphere, in this lesson.

Marine Resources: Characteristics, Formation & Management

13. Marine Resources: Characteristics, Formation & Management

What are marine resources? Learn about the characteristics, how they form, and some of the best ways we can manage them for future generations. Take a quiz to test your knowledge.
