Ch 17: Properties of Oceans

About This Chapter

This earth science chapter can help you boost your understanding of the ocean's properties for upcoming exams and assignments. You'll be able to use any Internet-connected device to access the chapter's engaging lessons and self-assessment quizzes.

Properties of Oceans - Chapter Summary

Review the properties of oceans with this engaging earth science chapter. As you follow along with our expert instructors, you'll define basic ocean terminology and explore topics like ocean basins, ocean water, beaches, waves, tides and ocean circulation. Each lesson comes with a short quiz, and the chapter concludes with a comprehensive multiple-choice exam. You can study ocean properties wherever and whenever it's convenient, and our instructors are happy to assist you if you have any questions about the material. Upon completion of the chapter, you should be able to:

  • Differentiate between active and passive continental margins
  • Interpret facts about continental slope
  • Outline the formation of accretionary wedges, ocean basins and the oceanic ridge system
  • Define mid-ocean ridges
  • Assess ocean water properties
  • Identify several types of marine organisms
  • Describe the ocean food chain
  • Describe the characteristics of beaches and shorelines
  • Compare different types of waves
  • Evaluate the causes and effects of tides
  • Explain the concept of longshore transport
  • Understand how ocean circulation affects climate

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.

Continental Slope: Definition & Facts

2. Continental Slope: Definition & Facts

Continental slopes are one of three parts that make up the under-ocean margin surrounding the continents of the world. In this lesson, you'll learn what they are, where they are, and what some of their characteristics are.

Accretionary Wedge: Definition & Formation

3. Accretionary Wedge: Definition & Formation

Where two tectonic plates collide and one dives below the other, you'll always find accretionary wedges. Read this lesson to learn how these deposits form and what they are made of.

Ocean Basins: Definition, Formation, Features & Types

4. 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

5. 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.

Mid-Ocean Ridge: Definition, Facts, Formation & Example

6. Mid-Ocean Ridge: Definition, Facts, Formation & Example

Mid-ocean ridges...on the surface, it sounds obvious what these might be, but there are complicated forces that create them. Here, you will learn what mid-ocean ridges are, where they are, how they are created, and what makes them fascinating geological formations.

Properties of Ocean Water

7. 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.

Types of Marine Organisms

8. Types of Marine Organisms

Many marine organisms thrive under the surface of the ocean. Learn about the biodiversity of the oceans, from the microscopic plankton to the enormous whales, and how these organisms adapt to their oceanic environment.

Ocean Food Chain

9. Ocean Food Chain

This lesson is on ocean food chains. In this lesson, we'll go over what a food chain is and what the different oceans are. Then, we'll get into two specific food chains in the Arctic and Pacific Ocean.

Characteristics of Shorelines & Beaches

10. 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.

Waves: Types, Features & Effect on Erosion

11. 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

12. 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

13. 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.

Ocean Circulation: Patterns & Effect on Climate

14. 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.
