About This Chapter
CSET Science: Geodynamics - Chapter Summary
The lessons in this chapter will help you prepare for the geodynamics questions on the California Subject Examinations for Teachers (CSET). You'll gain a solid understanding of how plate tectonics is responsible for many of Earth's surface features. Other lessons will explore the reshaping of the planet by factors such as weathering and depositing of sediment. The effect of heating and the water cycle will be discussed, and you'll study rocks and how they were formed. This chapter's lesson topics include:
- Internal and external forces that shape Earth's surface
- Plate tectonics: a unified theory for change of the Earth's surface
- Summary of earthquake processes in terms of epicenter, focal mechanism, distance and materials and the role of various factors in the amount of damage incurred
- Igneous, sedimentary and metamorphic rocks
- Methods of geological dating: numerical and relative
- Theories of geological evolution: catastrophism vs. uniformitarianism
- Effects of erosion and deposition on landforms
- How a landform diagram describes the geological progression of a landscape
- Earthquakes and volcanoes: evidence of Earth's inner layers
- Transport as a dynamic process
- Effects of ground and surface water on landscapes
- Fighting soil erosion with sustainable soil use
- Natural hazards, earthquakes, volcanic eruptions, landslides, floods and their effects on habitats and environments
- The water cycle: precipitation, condensation and evaporation
- Daily and seasonal changes in the sky
- Active and passive solar heating
- Types of air masses and their effect on weather
- Interpretation of weather maps to predict weather patterns
These topics will be explained by expert instructors who make learning about the Earth's dynamism fun. You'll get sound explanations of many of the past and ongoing changes in our planet in preparation for the CSET Science exam questions on geodynamics.
Objectives of the CSET Science: Geodynamics chapter
California requires certain teacher credentialing candidates to pass CSET examinations. The geodynamics questions on the CSET are included in the General Science: Subtest I. This science subtest contains 58 multiple-choice questions, with 15 of those on the Earth's dynamic processes. You'll also be asked to write a short response to a question on geodynamics. You can get an idea of what the CSET will be like, as well as test your knowledge, through the self-assessment quizzes that accompany each video lesson.
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. Ground and Surface Water: Effects On Landscapes
In this lesson, you will learn how groundwater and surface water form features on Earth and cause changes in landscapes. You will also learn about the different types of features formed by each type of water.
4. Formation of the Earth: Theories
In this lesson, the theory of how the planet Earth formed will be discussed. This includes looking at how it differentiated into three layers, how it formed its atmosphere, water, and land features, and how it continues to evolve today.
5. The Changing Earth: Volcanoes, Weathering & Deposition
While we may not see it every day, the world is always changing. In this lesson, with the help of an ill-informed tour guide, we will see how volcanoes, weathering, and deposition work to continually change the surface of our planet.
6. Geologic Time Scale: Major Eons, Eras, Periods and Epochs
The geologic time scale is an essential tool for understanding the history of Earth and the evolution of life. In this lesson, explore the principal eons, eras, periods, and epochs that help us track major events in geologic history.
7. What is Relative Dating? - Law of Superposition, Principles of Original Horizontality & Cross-Cutting Relationships
Discover how geologists study the layers in sedimentary rock to establish relative age. Learn how inclusions and unconformities can tell us stories about the geologic past. We'll even visit the Grand Canyon to solve the mystery of the Great Unconformity!
8. Absolute Age: Definition & Dating
Imagine braving the desert heat for days or even weeks as you dig for dinosaur bones. You find something extraordinary and want to know as much about it as you can. In this lesson, you'll learn how scientists determine the absolute age of materials.
9. Principles of Radiometric Dating
Radiometric dating is a method used to determine the age of rocks and other materials based on the rate of radioactive decay. Learn about three common types of radioactive decay: alpha decay, beta decay and gamma decay.
10. Radiometric Dating: Methods, Uses & the Significance of Half-Life
Radiometric dating is used to estimate the age of rocks and other objects based on the fixed decay rate of radioactive isotopes. Learn about half-life and how it is used in different dating methods, such as uranium-lead dating and radiocarbon dating, in this video lesson.
11. Factors Affecting Energy Flow in Earth's Systems
Factors that affect Earth's systems can occur naturally or through human induced changes. They can alter the energy flow or balance of the Earth. In this lesson, you will learn how factors like volcanoes and vegetation alter this flow.
12. 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.
13. The Distribution of Water on Earth
Water covers most of Earth but in a variety of forms. In this video lesson you will learn about how water is distributed on Earth, though you may be surprised to find out just how little of it we can access!
