About This Chapter
Understanding Running Water - Chapter Summary
This convenient earth science chapter provides an overview of running water topics. Inside, you'll find short and engaging lessons that examine the features of running water systems, the effects of erosion, landform diagrams and much more. You can supplement your studying experience by taking the accompanying multiple-choice quizzes and chapter exam. Our instructors are available to answer any questions you may have, and you can review the chapter material at any time that fits your schedule. Studying these lessons can help you:
- Recognize the characteristics of drainage basins
- Describe turbulent and laminar streamflows
- Understand how landforms are affected by erosion and deposition
- Identify factors that influence river water movement
- Interpret landform diagrams to describe a landscape's geological progression
- Outline the formation of stream valleys and bedrock channels
- Assess the effect of erosion on a stream's base level
- Evaluate the development of a floodplain
- Compare different types of alluvial channels
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. 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.
4. Factors That Influence Water Movement in River Systems
River systems are complex and diverse. In this lesson, we will explore four main factors that influence the behavior, shape, and movement of water through a river.
5. 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.
6. 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.
7. 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.
8. Floodplain: Definition, Development & Features
Floodplains can be a small part of the landscape or a gigantic feature. Here, you will learn what floodplains are, how they are formed, why they are important and where you can find some major floodplains in the world.
9. 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.
10. 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.
