Ch 8: Running Water & the Landscape

About This Chapter

Use these video lessons to review the characteristics of drainage basins, bedrock channels and alluvial channels. You'll also examine the effects of rivers and streams on the landscape.

Running Water & the Landscape - Chapter Summary

This chapter's video lessons can help you take a closer look at the relationship between rivers, streams and the physical features of a landscape. You'll explore the roles of drainage basins in the formation of river systems and study the differences between laminar and turbulent streamflows. Our instructors also explain the effects of erosion, deposition and other forms of weathering on the Earth's surface before outlining the key terms and concepts needed to read a landform diagram.

In the second half of the chapter, you'll take a closer look at stream valley formation and the effects of a stream's base level on erosion. You can also discover the processes by which bedrock channels and alluvial channels are formed. Topics covered in this chapter include:

  • Landform diagrams
  • Drainage basins
  • Erosion and deposition
  • Stream valleys and channels
  • Streamflows
  • Landform diagrams

Resources included in our Running Water & the Landscape chapter are available for viewing whenever you have the opportunity to fit some study time into your schedule. Plus, you can start, stop and resume the video lessons or retake the quizzes as many times as you need to feel comfortable with these Earth science topics.

Drainage Basins: Definition & Characteristics

1. 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.

Laminar & Turbulent Streamflows

2. 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.

How a Landform Diagram Describes the Geological Progression of a Landscape

3. 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.

The Formation of Stream Valleys

4. 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.

Base Level of a Stream: Definition & Effect on Erosion

5. 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.

Bedrock Channels: Formation & Process

6. 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.

Alluvial Channels: Definition & Types

7. 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.
