Ch 14: ScienceSaurus Student Handbook Grades 6-8: Geology

About This Chapter

The Geology chapter of this ScienceSaurus Student Handbook Grades 6-8 Companion Course helps students learn the essential lessons associated with geology. Each of these simple and fun video lessons is about five minutes long and is sequenced to align with the Geology textbook chapter.

How It Works:

  • Identify the lessons in the ScienceSaurus Geology chapter with which you need help.
  • Find the corresponding video lessons with this companion course chapter.
  • Watch fun videos that cover the geology 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 inner composition and structure
  • Geodesy
  • Identifying minerals and rocks
  • The different tectonic plates and plate boundaries
  • Components of earthquakes
  • Kinds of mountains and volcanic deposits
  • Types of weathering and causes of soil erosion
  • Characteristics of drainage basins
  • How the Earth formed
  • Types of fossils and geological dating methods

The Layers of the Earth: Facts, Composition & Temperature

1. The Layers of the Earth: Facts, Composition & Temperature

This lesson will discuss the layers that make up the inside of the Earth chemically, including their composition, temperatures, and the states. A short quiz will follow.

Shape of the Earth: Density, Stress & Gravity

2. Shape of the Earth: Density, Stress & Gravity

This lesson will seek to explain geodesy and the Earth's shape. In doing so, it will highlight the concepts of gravity, density, and stress, as well as the role they play in the field of geodesy.

Rocks and Minerals: Definitions and Differences

3. Rocks and Minerals: Definitions and Differences

Can you tell the difference between a rock and a mineral? What makes a mineral so much different from a rock? Explore these questions in depth, and learn how we classify rocks and minerals.

Major Plates of the Lithosphere: Earth's Tectonic Plates

4. Major Plates of the Lithosphere: Earth's Tectonic Plates

The outer shell of the earth, the lithosphere, is broken up into tectonic plates. The seven major plates are the African plate, Antarctic plate, Eurasian plate, Indo-Australian plate, North American plate, Pacific plate and South American plate.

The Processes of Mountain Building

5. 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.

Plate Boundaries: Convergent, Divergent, and Transform Boundaries

6. Plate Boundaries: Convergent, Divergent, and Transform Boundaries

In the theory of plate tectonics, the earth's crust is broken into plates that move around relative to each other. As a result of this movement, three types of plate boundaries are formed: divergent, convergent, and transform boundaries.

What is an Earthquake? - Definition and Components

7. 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.

Volcanic Deposits: Definition & Explanation

8. Volcanic Deposits: Definition & Explanation

Discover what happens to the landscape after a volcano erupts. Learn how deposits from volcanoes create mountains, islands and even precious minerals.

Mechanical Weathering: Definition, Process, Types & Examples

9. Mechanical Weathering: Definition, Process, Types & Examples

Over time, the forces of the natural environment cause rocks to physically break down in a process called mechanical weathering. Learn how factors, such as wind, water and temperature fluctuations lead to mechanical weathering.

What is Chemical Weathering? - Definition, Process & Examples

10. What is Chemical Weathering? - Definition, Process & Examples

Chemical weathering is what happens when rocks are broken down and chemically altered. Learn about the different types of chemical weathering, including hydrolysis, oxidation, carbonation, acid rain and acids produced by lichens.

What is Soil Erosion? - Definition and Causes

11. What is Soil Erosion? - Definition and Causes

With soil erosion, the top layer of soil is worn away due to factors such as water, wind and tillage of farmland. Learn about soil erosion and how natural elements and human activities break up and transport soil.

Drainage Basins: Definition & Characteristics

12. Drainage Basins: Definition & Characteristics

Do you know where the water in your area flows? In this lesson, we will explore the system of drainage basins and how they help develop river systems. We will also investigate some extreme examples of drainage basins.

Formation of the Earth: Theories

13. 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.

Methods of Geological Dating: Numerical and Relative Dating

14. Methods of Geological Dating: Numerical and Relative Dating

Learn how scientists determine the ages of rocks and fossils. We'll explore both relative and numerical dating on our quest to understand the process of geological dating. Along the way, we'll learn how stratigraphic succession and radioactive decay contribute to the work of paleontologists.

Fossil: Definition, Types, Characteristics & Examples

15. Fossil: Definition, Types, Characteristics & Examples

Fossils provide scientists with many clues about Earth's history, offering evidence of dinosaurs and strange plants that existed in the past. This lesson will define a fossil, look at different types and characteristics of fossils, and then describe how fossils are formed.
