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.

Ocean Basins: Definition, Formation, Features & Types

2. 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

3. 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.

Properties of Ocean Water

4. 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

5. 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.

Characteristics of Shorelines & Beaches

6. 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.

Ocean Circulation: Patterns & Effect on Climate

7. 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.

Waves: Types, Features & Effect on Erosion

8. 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.

Contributing Factors of Longshore Transport: Beach Drift & Longshore Current

9. 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.

What Are Tides? - Causes & Effects

10. 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.

Orographic Effect: Definition & Concept

11. Orographic Effect: Definition & Concept

This lesson describes the orographic effect. It also explains how this process can lead to vast differences in the level of vegetation on the two sides of a mountain.

What is a Beach? - Definition, Formation & Characteristics

12. What is a Beach? - Definition, Formation & Characteristics

This lesson is about beaches. Although beaches are pretty common, there's a lot of complex science behind their formation. We'll talk about the characteristics of beaches and how geological processes form them in this video.

Changes in Sea Level: Causes & the Effect on the Environment

13. Changes in Sea Level: Causes & the Effect on the Environment

Sea level rise is a natural process, but recent trends are concerning because it is increasing at an alarming rate. In this lesson, you'll learn what causes changes in sea level and what effect rising sea level has on humans and the environment.

The Scientific Field of Oceanography

14. 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.

Theories About How Oceans Were Formed

15. Theories About How Oceans Were Formed

Today, more than 2/3 of Earth is covered with water, mostly in our oceans. But Earth itself is much older than our oceans. In this lesson you'll explore theories on how our oceans formed, as well as why liquid water remains on Earth even after all this time.

Threats to the Ocean: Human Impact & Solutions

16. Threats to the Ocean: Human Impact & Solutions

In this lesson we'll be learning about how humans are harming our oceans through pollution, global warming and over fishing. But, don't despair! We'll also examine solutions to these problems to help preserve our oceans for generations to come.

What is Blue Biotechnology? - Applications & Examples

17. What is Blue Biotechnology? - Applications & Examples

You may be surprised to learn that many things you use regularly either come from or are derived from aquatic organisms. This lesson will explore this blue biotechnology, providing examples of how your world wouldn't be the same without it.

What is a Tidal Bore? - Definition, Cause & Wave

18. What is a Tidal Bore? - Definition, Cause & Wave

Every day on Earth, there are two high tides and two low tides, but not every location experiences a tidal bore. In this lesson, we will learn what a tidal bore is, and what causes it.
