About This Chapter
AFOQT: Earth Science - Chapter Summary
The earth science subjects that you will encounter in this chapter include the definition of earth science, the impact of erosion on landforms, ways a landform diagram can provide descriptions of the geological processes and more! Brief yet engaging text and video lessons will help you remember information you may have forgotten about earth science for the General Science section of the AFOQT exam. Our quick multiple-choice quizzes prepare you to answer questions much like the ones you will see on your exam. Other subjects you will find in this chapter include the following:
- How earthquakes provide information about Earth's layers
- The different types of rocks and the rock cycle
- Important meteorology, oceanography, and astronomy concepts
- Solar and lunar eclipses
After you are finished gauging your knowledge with the quizzes, you can also take the chapter and final exams. All of the study resources in this chapter are mobile friendly, so you can study wherever you please. Lesson transcripts are also available for you to review.
1. What is Earth Science?
Earth science is a field that includes geology, astronomy, meteorology, and oceanography. Scientists do research in these fields to discover past and future events. Learn about the dynamic field of earth science and how it affects our lives in this lesson.
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. 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. 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.
5. Rock Cycle: Igneous, Sedimentary, and Metamorphic Rocks
In this lesson, we will discuss the three main types of rocks and how they are formed. The lesson also gives an introduction into how matter locked in rocks can be cycled through the earth.
6. What is Meteorology? - Definition, History & Facts
Meteorology is the study of Earth's atmosphere. In this lesson, learn the difference between meteorology and climatology, and explore the history and interdisciplinary nature of its study.
7. What is Oceanography? - Definition, History & Facts
While over 70% of the earth is covered by the oceans, much of it remains a mystery. Its immense size and depth entice scientists to uncover these mysteries. In this lesson, you'll learn about oceanography, the field that studies the world's oceans.
8. What is Astronomy? - Definition, History, Timeline & Facts
When you look up at a clear night sky, how many stars do you see? Probably more than you can even count! What's more incredible is just how large and far away those stars are, and how much we can learn about our universe by looking at starlight.
9. What is a Lunar Eclipse? - Definition, Facts & Frequency
In this lesson, you will learn what a lunar eclipse is and how frequently lunar eclipses occur. You will also learn facts related to lunar eclipses, which are studied by scientists all over the world.
10. What Is a Solar Eclipse?
This lesson will describe what a solar eclipse is, why it's possible, when a partial or a total one will occur, and what cool effects occur during one.
