About This Chapter
Rivers & Coasts - Chapter Summary
Students can use this engaging online chapter to gain full comprehension of the geomorphological processes of rivers and coasts, no matter their current level of understanding. Lessons quickly and easily enable students to grasp concepts that include weathering, coastal erosion and the geological progression of landscapes. Upon completion of this chapter, students should be prepared to:
- Discuss the impact of erosion and deposition on landforms
- Define valleys and explain how rivers and streams affect the Earth's surface
- List and describe landforms created by waves
- Explain the formation and characteristics of a beach
- Share causes of coastal transportation
- Describe contributing factors of longshore transport
- Identify causes and types of floods and discuss ways to prevent them
- Detail the causes and aftermath of the 1931 China floods
To get started, students can select the lesson they want to study, review it, and take its accompanying quiz or scroll for new lessons along the right-hand sidebar. If they hit a snag and need additional information, they can send their questions to our experts using the Dashboard. A practice exam is available to provide students with a well-rounded review of rivers and coasts. All resources in this chapter are accessible 24/7 to ensure students can study whenever their schedules allow.
1. Weathering: Definition, Types, Causes & Rates
Ever wondered how erosion could create something as dramatic as the Grand Canyon? The simple answer is weathering. This lesson describes the three major types of weathering, their causes, and how weathering rates can change.
2. What is Coastal Erosion? - Definition & Causes
Communities falling into the ocean? It sounds like a scene from a science fiction movie, but it happens in the real world. This lesson will examine the five mechanisms that cause coastal erosion and put some coastal communities at risk.
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. Valley: Definition & Examples
Explore the types of valleys created by erosion and the shifting of the earth's plates. Learn about the different shapes valleys can take, from steep river canyons to wide glacier valleys.
5. 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.
6. Landforms Created by Waves
After completing this lesson, you will be able to list coastal landforms and describe how waves create them. A short quiz to test your knowledge follows the lesson.
7. What is a Beach? - Definition, Formation & Characteristics
This lesson is about beaches. Although beaches are pretty common, there's a lot of complex science behind their formation. We'll talk about the characteristics of beaches and how geological processes form them in this video.
8. What is Coastal Transportation? - Definition & Causes
We are going to discuss what coastal transportation is and look at the various methods by which coastal transportation can occur. The type of materials moved by each method will also be discussed.
9. Contributing Factors of Longshore Transport: Beach Drift & Longshore Current
The longshore transport is the process responsible for the movement of sand and sediment along the coastline. Sand and other particles are transported with the help of the longshore current and beach drift. Learn how these factors shape shorelines.
10. 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.
11. What Are Floods? - Causes, Types & Prevention
In this video lesson, you will study floods, their causes and their effects. You will learn to identify various methods that are used to prevent floods and explore how preventing natural flood cycles can lead to dangerous flood events.
12. 1931 China Floods: Facts, Causes & Aftermath
The year 1931 was a big one in Chinese history. In this lesson, we're going to explore one of the worst natural disasters in all of human history and see how it impacted China for decades to come.
