Ch 3: Holt McDougal Environmental Science Chapter 3: The Dynamic Earth

About This Chapter

The Dynamic Earth chapter of this Holt McDougal Environmental Science Companion Course helps students learn the essential lessons associated with the dynamic Earth. Each of these simple and fun video lessons is about five minutes long and is sequenced to align with the Dynamic Earth textbook chapter.

How It Works:

  • Identify the lessons in the Holt McDougal Dynamic Earth chapter with which you need help.
  • Find the corresponding video lessons with this companion course chapter.
  • Watch fun videos that cover the dynamic Earth topics you need to learn or review.
  • Complete the quizzes to test your understanding.
  • If you need additional help, rewatch the videos until you've mastered the material or submit a question for one of our instructors.

Students will learn:

  • Earth's four spheres
  • Each of Earth's internal layers
  • The theory of plate tectonics
  • How volcanoes and earthquakes are defined
  • Mountain building processes
  • Kinds of weathering
  • The composition of Earth's atmosphere
  • Heat transfer mechanisms
  • Causes and effects of global warming
  • Water cycle phases
  • Ocean water properties
  • Different ocean circulation patterns

The Four Spheres of Earth: Geosphere, Hydrosphere, Biosphere, and Atmosphere

1. The Four Spheres of Earth: Geosphere, Hydrosphere, Biosphere, and Atmosphere

Earth is made up of four distinct yet connect spheres. In this video lesson, you will learn about where each sphere is found on Earth, as well as some features commonly found in each.

Earth's Internal Layers: Crust, Mantle & Core

2. Earth's Internal Layers: Crust, Mantle & Core

Earth is made up of several different layers, each with unique properties. In this video lesson, you will identify each layer of Earth and how it relates to Earth as a whole.

Plate Tectonics: A Unified Theory for Change of the Earth's Surface

3. Plate Tectonics: A Unified Theory for Change of the Earth's Surface

After many years of trying to solve the mystery of the moving continents, enough data and evidence was collected to develop a unifying theory of how the surface of the earth changes. It's called plate tectonics.

What is an Earthquake? - Definition and Components

4. 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.

What is a Volcano? - Definition & Eruptions

5. What is a Volcano? - Definition & Eruptions

Volcanoes are vents that allow lava, rock fragments and gases to escape from layers beneath the earth's surface. Learn how volcanoes form both on land and underwater and why they erupt.

The Processes of Mountain Building

6. The Processes of Mountain Building

In this video lesson, you will learn about the process of mountain building. You will identify different ways that mountains form, as well as the different types of mountains that result from this process.

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.

Wind Action & Effects on the Desert Landscape

8. Wind Action & Effects on the Desert Landscape

Wind is a powerful force that has the ability to shape a landscape. In deserts, wind action changes the landscape through wind erosion in the form of abrasion and deflation.

Major Components of the Atmosphere

9. Major Components of the Atmosphere

Our atmosphere is a complex mixture of many different gases. In this video lesson you will identify the major components of Earth's atmosphere as well as how much there is of each.

The Structure of the Atmosphere

10. The Structure of the Atmosphere

If you've ever climbed a mountain or been to the beach, you know that the atmosphere is different at different levels. This lesson explains how the structure of the atmosphere is really like a layer cake.

Mechanisms of Heat Transfer: Conduction, Convection & Radiation

11. Mechanisms of Heat Transfer: Conduction, Convection & Radiation

There are three main ways that heat is transferred between substances or objects. In this video lesson you'll learn about each one, and identify the differences between them.

Global Warming: Atmospheric Causes and Effect on Climate

12. Global Warming: Atmospheric Causes and Effect on Climate

Global warming is a multifaceted, complex issue. It involves both natural and human causes that can increase the amount of greenhouse gases. This lesson looks at some of the facts about global warming and how they could contribute to climate change.

The Water Cycle: Precipitation, Condensation, and Evaporation

13. The Water Cycle: Precipitation, Condensation, and Evaporation

This lesson discusses the processes water takes as it moves around the Earth in the water cycle. You'll get an in-depth look at condensation, precipitation, and evaporation.

Properties of Ocean Water

14. Properties of Ocean Water

Ocean waters are salty and contain minerals and dissolved gases. They also have a high heat capacity and vary in density depending on temperature and salinity. Learn more about the unique chemical and physical properties of ocean water.

Ocean Circulation: Patterns & Effect on Climate

15. Ocean Circulation: Patterns & Effect on Climate

The ocean waters are always in motion and as they travel around the globe they carry and distribute heat, which affects the global climate. Learn about the ocean circulation patterns and how they impact the climate.

Biosphere: Definition & Explanation

16. Biosphere: Definition & Explanation

All organisms, from the tiniest bacterium to the largest blue whale, need a place to live. The 'place on Earth's surface where life dwells' is called the biosphere. But what does this really mean? In this lesson, we'll look at the definition of the biosphere and examine how human activity is changing this important part of our planet.
