About This Chapter
MEGA Earth Science: Processes of Earth's Surface- Chapter Summary
If you want to pass the MEGA Earth Science exam, you will need to be familiar with the material explored in this chapter. The lessons will cover important information about earthquakes and erosion. By the end of these video lessons, you will have an understanding of the following topics:
- Forces that shape the Earth's surface
- Erosion and deposition effects on landforms
- Earthquakes and volcanoes
- Coast erosion
- Deposition on shoreline
- Causes of earthquakes
- Aftershocks and foreshocks
- Earthquake destruction
- Seismic activity
- Active and passive continental margins
All of the resources that are available to you in this chapter can be accessed numerous times. You won't be forced to move forward in the lesson until you feel confident enough to. The timeline feature tracks your progress as well. When you are ready, you can take the chapter test on all of the lessons in this chapter.
1. The Dynamic Earth: Internal & External Forces that Shape Earth's Surface
There are many geologic processes that shape the surface of the Earth. Not only do they build and destroy a variety of landscapes, but they also give us clues to the interior of the Earth and the forces that exist there.
2. 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.
3. Earthquakes and Volcanoes: Evidence of Earth's Inner Layers
The interior layers of the earth are not able to be observed directly, so scientists need to rely on other information to learn about it. S waves, P waves, and magma from volcanoes and earthquakes give a glimpse at the layers of the earth by providing data that can be built into a model of the earth.
4. The Effects of Coastal Erosion on Shoreline Features
Shorelines constantly change due to the pounding of waves that erode coastal structures. Learn about shoreline features that are formed through coastal erosion, such as wave-cut cliffs, wave-cut platforms, sea arches and sea stacks.
5. The Effects of Deposition on Shoreline Features
Shorelines constantly change due to the depositing of sand and sediment, which is a process known as deposition. Learn about shoreline features that are created by deposition, such as spits, baymouth bars, tombolos and barrier islands.
6. The Causes of Earthquakes
In this video lesson you will learn what causes earthquakes and where they occur. You will also understand the theory of elastic rebound, and how this relates to movement of the earth's crust.
7. Aftershocks & Foreshocks of an Earthquake
An earthquake is not an isolated event of ground shaking. Foreshocks and aftershocks occur with most earthquakes, and in this video lesson you will learn about them and how they are part of the overall process.
8. Destruction Caused by Earthquakes
Earthquakes are well-known for their damage and destruction, and in this video lesson you will learn about the different types of damage that these dangerous natural disasters can cause.
9. Identifying and Understanding Earthquakes Using Seismic Activity
Scientists can learn a lot about earthquakes by studying how they move ground. Using seismic activity, we can learn where an earthquake originated as well as how strong it was. In this video lesson, you will learn about seismic activity and how it relates to our understanding of earthquakes.
10. Active & Passive Continental Margins
Continental margins are areas that separate the continental crust and oceanic crust. Discover the differences between the tectonically active continental margins and the relatively quiet passive continental margins.
