About This Chapter
Types of Running Water - Chapter Summary
This chapter covers lessons that will teach you all about running water, including its effect on landforms and landscapes. You will learn how running water causes erosion and deposition, the base level of a stream and alluvial and bedrock water channels.
The lessons in this chapter will help you learn about the following topics:
- Drainage basins
- Turbulent and laminar streamflows
- How deposition and erosion affect landforms
- Ways that a landform diagram can help to illustrate a landscape's geologic progression
- Process of forming stream valleys
- How the base level of a stream affects erosion
- Bedrock and alluvial channels
This chapter will get you up to speed on running water with short video lessons and multiple-choice quizzes. Each lesson features an interactive timeline so you can quickly jump to specific topics within the video. Use the lesson transcript as an extra study resource, then test yourself with practice quizzes and the chapter exam.
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.
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.
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.
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.
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.
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.
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.
