Ch 47: Praxis Biology & General Science: Earth and Space: Earthquakes and Earth's Surface

About This Chapter

Let us teach you about earthquakes and the Earth's surface. The video lessons and self-assessment quizzes on the roles volcanoes, earthquakes and erosion play in forming geological features can help you answer these types of questions on the Praxis II Biology and General Science exam.

Praxis II Biology & General Science: Earthquakes and Earth's Surface - Chapter Summary

Use this chapter's video lessons to prepare for Praxis II Biology and General Science exam questions covering the internal and external forces shaping the Earth's surface. Instructors discuss the definition and history of earthquakes, evidence of the Earth's inner layers and sustainable soil use in addition to the topics listed below:

  • Earthquakes and volcanoes
  • Causes of earthquakes
  • Aftershocks and foreshocks
  • Seismic waves and earthquake research
  • The Richter scale
  • Effects of erosion and deposition
  • Soil conservation
  • Landform diagrams

This chapter's short, engaging video lessons can give you an idea of what's covered on the exam, and the corresponding quizzes can show you how the multiple-choice questions are formatted. Use them together to study new terminology and review familiar concepts in time for exam day.

Praxis II Biology & General Science: Earthquakes and Earth's Surface Chapter Objectives

Some states require aspiring high school biology or general science teachers to earn passing scores on the Praxis II Biology and General Science exam before they can qualify for a license. This standardized test consists of 120 multiple-choice questions that must be completed within two hours of testing time.

The Earthquakes and Earth's Surface chapter contains video lessons and quizzes that can help you answer geology questions found in the exam's Earth and Space Science content domain. This area of the test includes approximately 12 multiple-choice questions. You'll be asked to select the appropriate response to an incomplete statement or query about topics including plate tectonics and soil erosion.

Earthquakes and Volcanoes: Evidence of Earth's Inner Layers

1. 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.

What is an Earthquake? - Definition and Components

2. What is an Earthquake? - Definition and Components

Earthquakes are well known for the damage and destruction they leave behind. But what is an earthquake? In this video lesson you will learn about what causes earthquakes and the various components involved in these powerful natural disasters.

The Causes of Earthquakes

3. 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.

Aftershocks & Foreshocks of an Earthquake

4. 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.

Identifying and Understanding Earthquakes Using Seismic Activity

5. 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.

Using the Richter Scale to Measure Earthquakes

6. Using the Richter Scale to Measure Earthquakes

In this video lesson, you will learn about earthquake magnitude and how it is measured. You will also learn how that relates to the amount of energy released during an earthquake, as well as how common different magnitude earthquakes are around the world.

Effect of Erosion and Deposition on Landforms

7. 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.

Soil Conservation: Fighting Soil Erosion With Sustainable Soil Use

8. Soil Conservation: Fighting Soil Erosion With Sustainable Soil Use

In this lesson, you will learn about the causes of soil erosion and the impacts it has on plants and other resources. You will also learn about how erosion is prevented through land use and land monitoring.

How a Landform Diagram Describes the Geological Progression of a Landscape

9. 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.

The Dynamic Earth: Internal & External Forces that Shape Earth's Surface

10. 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.
