About This Chapter
Running Bodies of Water - Chapter Summary
This chapter helps your student learn about flowing water by using engaging, accessible videos to describe streams, currents, drainage and erosion. Students learn about the factors that influence the flow of water in a channel and consider the impact that human activity has on rivers and streams. Multiple-choice quizzes help students retain the facts by letting them use their new-found knowledge. If your middle-schooler would like additional help or advice, he or she can submit a question to one of our instructors.

1. Hydraulic Geometry in Water Flow
After watching this video, you will be able to explain what hydraulic geometry is. You'll also be able to describe the geometric features of a river at different points and how they are formed. A short quiz will follow.
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. 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.
4. Understanding Graded Streams
After watching this video, you should be able to explain what a graded stream is, how streams change over time, and how a balance in erosion and deposition can be reached. A short quiz will follow.
5. Effect of Erosion and Deposition on Landforms
Landforms are constantly being broken down and reformed by the processes of weathering, erosion, and deposition. In this lesson, we explore chemical and physical weathering and how the face of the earth gets changed.
6. Hillslope Erosion Process: Formation of Rills & Gullies
After watching this video, you will be able to explain what rills and gullies are, describe how they're formed, and how they relate to human activity. A short quiz will follow.
7. How a Landform Diagram Describes the Geological Progression of a Landscape
This lesson describes what a landform diagram is. We'll also discuss some basic laws of geology that can help scientists deduce both the order of events that create a landform and the geologic events that occur after a landform's formation.
8. The Formation of Stream Valleys
Running water is very powerful and has the ability to change the land around it. In this lesson, we will explore the creation of stream valleys and how they are shaped by the water that runs through them.
9. Base Level of a Stream: Definition & Effect on Erosion
Water stops flowing when it reaches its lowest level; this is called the base level. Learn about the base level of a stream, how it affects erosion, and some examples of local base levels, including lakes, dams and waterfalls.
10. Fluctuations in Stream Discharge
After watching this video, you will be able to explain what stream discharge is, as well as when and how it varies (or doesn't vary) over the course of a river. A short quiz will follow.
11. Bedrock Channels: Formation & Process
Bedrock channels are eroded paths cut through solid rock foundations known as bedrock. Learn about bedrock channels and the processes that form them, including abrasion and plucking.
12. Alluvial Channels: Definition & Types
An alluvial channel is a water channel made up of loose sediments called alluvium. Learn about the types of alluvial channels, meandering channels and braided channels, and the characteristics that make them unique in this lesson.
13. Effect of Humans on Streams
After watching this video, you will be able to explain and describe the various ways humans impact streams, including stream flow, pollution, and bodiversity. A short quiz will follow, providing an opportunity to see what you have retained from the lesson.
