About This Chapter
Oceans and Air Movement - Chapter Summary and Learning Objectives
Learn about ocean basins and the oceanic ridge system through this series of video lessons on oceans and air movement. This chapter will teach you about characteristics of shorelines and beaches and introduce the chemical and physical properties of ocean water. You'll also explore the relationship between oceanic and general atmospheric circulation. By the end of this chapter, you should be able to:
- Describe the movement of the ocean circulation pattern.
- Differentiate among the various types of ocean waves, including wind waves, tsunamis and tidal waves.
- Discuss the biodiversity of the oceans, from microscopic plankton to ocean-dwelling marine mammals like whales and manatees.
- Explain why passive processes such as coastal erosion and the passive depositing of sand and sediment dominate the East Coast of the U.S.

1. The Distribution of Water on Earth
Water covers most of Earth but in a variety of forms. In this video lesson you will learn about how water is distributed on Earth, though you may be surprised to find out just how little of it we can access!
2. How Continents & Oceans Influence Global Pressure Distribution
The movement of air in Earth's atmosphere is driven by several variables, including differences in pressure. Here we will examine how the presence of land and ocean affect differences in pressure, followed by a brief quiz to test your knowledge.
3. Oceanic & General Atmospheric Circulation
The movement of air and water across the planet is the driving force of climate and weather patterns. There are many factors that affect ocean and atmospheric circulation, and here we will explore what they are and how they function. At the end, you can test your knowledge with a brief quiz.
4. 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.
5. 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.
6. 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.
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.
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.
9. 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.
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.
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.
12. 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.
13. Ocean Upwelling: Definition & Types
Ocean currents play a critical role in climate and marine ecology. Upwelling areas are particularly important in both processes. Here we will examine what ocean upwelling is, how it works, some examples, and will finish with a brief quiz.
