Ch 20: Oceans & Coasts

About This Chapter

These brief, engaging video lessons in this geography chapter will help you teach your middle schoolers about ocean and coastal geography. The short quizzes following each lesson and the exam at the end of the chapter can help gauge their comprehension of these topics.

Oceans & Coasts - Chapter Summary

Do your middle schoolers need some help learning about the geography of oceans and coasts? The video lessons in this chapter have been created specifically for this age group to reinforce and clarify what they are learning in the classroom about geography. They'll learn about continental margins, types of marine organisms, types of waves, the cause and effect of tides and more. You'll also find short, multiple-choice lesson quizzes to check your middle schooler's comprehension of these concepts and the chapter exam can assure you they've retained the information.

The Earth's Oceans, Seas & Gulfs

1. The Earth's Oceans, Seas & Gulfs

As the Earth's surface is mostly made up of water, the different forms and bodies of it have different categories. Learn more about the bodies of water on the Earth, their characteristics, and locations.

Active & Passive Continental Margins

2. Active & Passive Continental Margins

Continental margins are the places where the continental crust meets the oceanic crust under coastal waters. Discover the makeup of Earth's continental and ocean crusts, then explore how active and passive continental margins are different.

Ocean Basins: Definition, Formation, Features & Types

3. Ocean Basins: Definition, Formation, Features & Types

Regions of the Earth found beneath sea level are known as ocean basins. Discover the different types of ocean basins, their features, and how they form, and explore the deepest parts of the ocean: oceanic trenches.

Oceanic Ridge System: Formation & Distribution

4. Oceanic Ridge System: Formation & Distribution

The oceanic ridge system is an underground mountain range formation on the sea floor. Discover the tectonic activity that led to the formation of the oceanic ridge system, and explore the distribution of the mountain chain, parts of which can be found in every ocean.

Properties of Ocean Water

5. Properties of Ocean Water

The salty waters of the ocean have their own unique properties that differ from those of freshwater. Although salt is the main chemical found in ocean water, there are many others, including dissolved gases. Explore the properties of ocean water, including salinity, temperature, heat capacity, and density.

Types of Marine Organisms

6. Types of Marine Organisms

Marine organisms are the variety of living creatures, large and small, that fill the oceans. Learn about diverse marine organism types: plankton, plants, algae, invertebrates, fish, marine mammals, reptiles, and sea birds, and how they adapt to different oceanic environments.

Ocean Circulation: Patterns & Effect on Climate

7. Ocean Circulation: Patterns & Effect on Climate

Ocean circulation refers to the patterns of water movement in ocean basins. Learn about ocean circulation, and explore how the patterns of ocean currents affect the climate. Gain understanding by reviewing ocean gyres, upwelling, and thermohaline circulation.

Characteristics of Shorelines & Beaches

8. Characteristics of Shorelines & Beaches

Shorelines and beaches are places where land meets a body of water, such as a lake or ocean. Learn the characteristics of a shoreline and understand the differences between headlands, bays, beaches, longshore drifts, and sandbars.

Waves: Types, Features & Effect on Erosion

9. Waves: Types, Features & Effect on Erosion

Review ocean waves' types, features, and effects on erosion. Differentiate between wind waves, ocean swells, tsunamis, and tidal waves and how the most powerful waves break down eroding coastal structures.

Contributing Factors of Longshore Transport: Beach Drift & Longshore Current

10. Contributing Factors of Longshore Transport: Beach Drift & Longshore Current

Longshore transport is the movement of sand and sediment parallel to the shore. Explore the factors contributing to how longshore transport occurs because of beach drift caused by the longshore current.

What Are Tides? - Causes & Effects

11. What Are Tides? - Causes & Effects

The term tides describe the daily changes in ocean water level seen at the coastline based on the gravitational pull of the sun and moon. Learn about the causes of high tides, low tides, semidiurnal tides, diurnal tides, spring tides, and neap tides, and explore their effects on coastal regions.

How Humans Manage and Interact with Coastlines

12. How Humans Manage and Interact with Coastlines

Humans have inflicted considerable damage on the world's coastlines, threatening the survival of these fragile ecosystems. Learn more about preventative measures intended to protect them from further destruction.
