Whether you love to study from home or on the go, this chapter can strengthen your understanding of the physical geography of the earth. You have the ability to access lessons from your computer or review them via your smartphone or tablet wherever you can secure an Internet connection. Before, during or after reviewing the lessons, be sure to assess your knowledge by taking multiple-choice quizzes. A practice chapter exam can help reinforce concepts covered in the lessons.
1. The Effect of Ice Age Glaciers: Formation of Pluvial Lakes
Ice age glaciers caused erosion and deposition, which resulted in unique features such as horns, cirques, lakes, U-shaped valleys, moraines and drumlins. Indirect effects include pluvial lakes, isostatic depression and a change in sea level.
2. Alfred Wegener's Theory of Continental Drift
People used to think that Earth was static, and that it never changed. Gradually, a body of evidence was gathered that made no sense in this model. Alfred Wegener, Geologic Supersleuth, laid the groundwork for a whole new theory for the large-scale changing nature of the earth.
3. Landform: Definition & Types
Read about landforms and their major features. Learn the differences between formations like mountains and hills, valleys and canyons. (Hint: It has to do with their form.)
4. The Processes of Mountain Building
In this video lesson, you will learn about the process of mountain building. You will identify different ways that mountains form, as well as the different types of mountains that result from this process.
5. Global Major Mountain Ranges
Learn about the six main mountain ranges of the world. Which is biggest? Which is longest? How do they form? Answer questions to test your new knowledge.
6. 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.
7. What is a Desert? - Definition & Facts
Do you know what a desert is? Did you know that a desert can be extremely cold and covered in snow? Read on to learn more fascinating facts about Earth's driest ecosystem.
8. Major Plates of the Lithosphere: Earth's Tectonic Plates
The outer shell of the earth, the lithosphere, is broken up into tectonic plates. The seven major plates are the African plate, Antarctic plate, Eurasian plate, Indo-Australian plate, North American plate, Pacific plate and South American plate.
9. Volcanoes: Formation & Locations
After completing this lesson, you will be able to describe how volcanoes form, and why they form in the particular locations they do. A short quiz will follow.
10. What is a Drought? - Definition, Causes & Facts
Think a drought is no big deal? Think again. In this lesson you'll learn what a drought is, how serious they can be, how droughts are categorized and how one area is dealing with an epic drought.
11. Natural Factors That Determine a Region's Climate
Climate is influenced by factors like atmosphere, ocean currents, landforms and plate tectonics. This lesson explains how these effects affect our weather patterns, which determine climate.
12. What Is an Ecosystem? - Definition & Explanation
Similar to a car engine that is made up of multiple parts working together, an ecosystem has interacting parts that support a whole. But how do we define an ecosystem and what are the components they consist of?
13. Land & Natural Resources: Scarcity & Allocation
This lesson explores the importance of two very unique resources to economic development: land and natural resources. It explains how land can last forever, while some natural resources can run out. That said, both require expert management.
