Ch 12: Ocean & Coastal Processes

About This Chapter

Use the following video lessons and quizzes to discover the processes of oceans and coasts. Find out about ocean basins, ridge systems, ocean water and much more.

Oceans and Coastal Processes

As you get started in this chapter, you'll learn about how ocean basins are formed and discover their different features and types. You'll get details on the oceanic ridge system, including how it was formed and how far it extends. You can find out about the geologic features of estuaries, barrier islands, capes and coral reefs.

Wave types and tides are discussed before moving on to the patterns of ocean circulation and how it affects the climate. You'll find out what generates a longshore current and why the shoreline isn't static. A major component of this chapter is the effect that human activity has on the coastal and marine environment. Key topics discussed in this chapter include:

  • Definition of an ocean basin
  • Geologic features of geomorphic structures
  • Relationship between waves and erosion
  • Causes and effects of tides
  • Ocean water properties
  • Surface currents, coastal upswelling and density-driven circulation
  • Longshore currents and beach drift

Our online video lessons about oceans and coastal processes are led by professional and knowledgeable instructors. These video lessons are accompanied by quizzes, transcripts and video tags. Gauge your understanding of the subject matter with the self-assessment quizzes then review major points in the lessons by using the video tags or searching the lesson transcripts.

Ocean Basins: Definition, Formation, Features & Types

1. 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

2. 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.

Waves: Types, Features & Effect on Erosion

3. 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

4. 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.

Ocean Circulation: Patterns & Effect on Climate

5. 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.

Properties of Ocean Water

6. 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.

Contributing Factors of Longshore Transport: Beach Drift & Longshore Current

7. 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.
