About This Chapter
Earth's Fresh Water - Chapter Summary
In this chapter's lessons, our instructors talk about fresh water on Earth and the ways in which its movement affects the planet's surface. You'll get information on drainage basins and types of streamflows. The information provided in these lessons should enable you to:
- Identify the physical characteristics of the Great Lakes
- Define watersheds and explain why they should be protected
- Explain the main features of rivers
- Understand the formation of lakes and ponds
- Discuss aquatic ecosystems
You can review these lessons on a computer or mobile device whenever it's convenient. The quizzes that follow them let you assess your knowledge and determine whether you need further review.
1. What is a Watershed? - Definition, Facts & Protection
Have you ever wondered what happens to rain after it hits the ground? In this lesson, we will trace the amazing journey a raindrop takes after it falls on land. You will learn a definition of a watershed and explore examples of how watersheds are protected.
2. Drainage Basins: Definition & Characteristics
Do you know where the water in your area flows? In this lesson, we will explore the system of drainage basins and how they help develop river systems. We will also investigate some extreme examples of drainage basins.
3. Rivers: Definition & Explanation
Explore rivers and how they develop from small streams to swiftly flowing rapids. Learn about how rivers shape the land around them, creating canyons, flood plains and deltas.
4. Lakes & Ponds: Formation & Features
After reading this lesson, you'll see just how similar lakes and ponds are along with what differentiates them. You'll now be able to tell your friend whether the body of water in his backyard is a lake or a pond.
5. Aquatic Ecosystems & Abiotic Factors
In this lesson, you will learn what aquatic ecosystems are. You will also learn about the abiotic factors that affect them, from light levels, to flow rate, to salinity.
6. Laminar & Turbulent Streamflows
Streams come in many different shapes and sizes. They can also vary in speed and direction of flow. In this lesson, we will explore two different ways that water can flow through a stream.
7. How Rivers and Streams Affect the Earth's Surface
Rivers and streams are powerful, ever-changing systems that can alter the surface of the Earth. While they share many similar features, they can be vastly different. In this lesson, we will learn how rivers and streams form, transport sediment, and flood.
8. Physical Characteristics of the Great Lakes
What makes the Great Lakes so great? Learn about the lakes' defining physical features and characteristics, and why they're so important to us. Find out how great you were at picking up this knowledge with a quiz.
