The Scientific Field of Oceanography

1. 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.

Active & Passive Continental Margins

2. 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

3. 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

4. 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.

Sediment: Definition, Types & Features

5. Sediment: Definition, Types & Features

Sediment is fragments of past living or non-living materials that have been broken down. There are three types of sediments that can form sedimentary rocks. Learn about clastic, biogenic and chemical sediments and the rocks they form in this lesson.

Natural Resources Obtained from the Ocean Floor

6. Natural Resources Obtained from the Ocean Floor

Rising prices of oil and gold and increased demand for steel ingredients like cobalt and manganese all point to a resource shortage. So, how do we handle that? Simple - we are beginning to look at the oceans for answers.
