The Earth's Oceans, Seas & Gulfs

1. The Earth's Oceans, Seas & Gulfs

After watching this video, you will be able to explain what oceans, seas and gulfs are and point out some of the most well-known ones on a world map. A short quiz will follow.

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.

Active & Passive Continental Margins

3. 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

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.

The Scientific Field of Oceanography

6. 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.
