The Distribution of Water on Earth

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!

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.

Oceanic Crust: Definition, Composition & Facts

3. Oceanic Crust: Definition, Composition & Facts

A thin layer of rock separates the Earth's oceans from the hot mantle beneath them. In this lesson, you'll read about the composition and life cycle of this oceanic crust. Then you can take a quiz to test your understanding.

Estuary: Definition, Facts, Characteristics & Examples

4. Estuary: Definition, Facts, Characteristics & Examples

Have you ever gone swimming, kayaking, or exploring in a marshy coastal area? If so, you were enjoying the natural beauty of an estuary, a place where rivers meet large bodies of water. These unique ecosystems are important, but also under threat.

Barrier Islands: Formation, Shape & Location

5. Barrier Islands: Formation, Shape & Location

In this lesson, we'll define barrier islands and learn how they form. We'll also look at how these types of islands, unlike other islands, can suddenly change shape or shift location over time. Lastly, we'll cover why these land masses are important to coastal areas.

Island, Reef & Atoll Formation: Steps & Stages

6. Island, Reef & Atoll Formation: Steps & Stages

Special features form in oceans where the water is relatively warm, and volcanic activity was present at some point in time. This lesson will go through the process involved in forming islands, reefs, and atolls.

What Are Tides? - Causes & Effects

7. 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.

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.

What are Ocean Currents? - Definition & Types

9. What are Ocean Currents? - Definition & Types

Currents are responsible for circulating water throughout the earth's oceans. This lesson will discuss surface ocean currents, deep water ocean currents, and the forces that drive them.

Sea Ice: Formation & Types

10. Sea Ice: Formation & Types

In this lesson we'll be learning about the different types of sea ice that cover the North and South poles. By the end of the lesson, you'll be able to explain what polar ice caps, icebergs, and glaciers are and how they form.
