Overview of Oceans & Coastlines - Chapter Summary

With these lessons, you will have the opportunity to learn from our instructors as they discuss the structures of the ocean floor, ocean circulation and coast lines. When you review the lessons, you should get a better understanding of:

  • The difference between active and passive continental margins
  • Formation, features and types of ocean basins
  • Distributions and formation of the oceanic ridge system
  • Patterns of ocean circulation and its effect on climate
  • Types of land forms created by ocean waves

Once the lessons have been reviewed, take the lesson quizzes to ensure that you understand the information that was covered. If you develop any questions about the content of this chapter, use the teacher tabs to ask our instructors for assistance.

Active & Passive Continental Margins

1. 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.

Ocean Basins: Definition, Formation, Features & Types

2. 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

3. 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.

Ocean Circulation: Patterns & Effect on Climate

4. 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.

Landforms Created by Waves

5. Landforms Created by Waves

After completing this lesson, you will be able to list coastal landforms and describe how waves create them. A short quiz to test your knowledge follows the lesson.
