Ch 10: Rocks & Weathering

About This Chapter

Go over topics relating to rocks and the process of weathering by watching the videos in this chapter. You will have the chance to explore different types of rocks and their characteristics.

Rocks & Weathering - Chapter Summary

View the videos in this chapter to build upon your knowledge of rocks. Deformation, rock cycles and different rock groups are covered as well.

Weathering is another topic discussed in depth in this chapter. You'll learn about the different types of weathering, such as chemical and mechanical weathering. Finishing this chapter gives you a great deal of knowledge about:

  • Causes of rock deformation
  • Types of rocks
  • Topography
  • Geological folds and faults
  • Factors that affect the rate of weathering
  • Effects of erosion
  • Ground and surface water
  • Structure and types of soil

Moving through the videos in this chapter doesn't take long, and the vdeos are designed to make learning fun. Use the self-assessment quizzes to check your knowledge after completing this chapter. You also have access to lesson transcripts containing important key words that are highlighted. This helps you review weathering and rock topics rather quickly.

Rock Cycle: Igneous, Sedimentary, and Metamorphic Rocks

1. 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.

Types of Rocks: The Three Major Rock Groups

2. Types of Rocks: The Three Major Rock Groups

Did you know that lava is molten rock that reaches the earth's surface? Furthermore, did you know that rocks exist in three general forms: igneous, sedimentary and metamorphic? This lesson describes these rock types and examples of each.

Rock Deformation: Causes and Types

3. Rock Deformation: Causes and Types

In this video lesson, you will learn about how rock can be deformed from stress and the effect this has on the rock. You will identify different types of deformation based on the composition of the rock as well as external stress factors.

Geological Folds: Definition, Causes & Types

4. Geological Folds: Definition, Causes & Types

Under the right conditions and over millions of years, rock can be deformed so that it is folded into a different shape. In this video lesson, you will identify different types of folds as well as what causes them to occur in rock.

Geological Faults: Definition, Causes & Types

5. Geological Faults: Definition, Causes & Types

In this video lesson, you will identify different faults and the types of stress that cause them. You will also see examples of the effects these faults have on the landscape.

What Is Topography and How Is Topography Reshaped?

6. What Is Topography and How Is Topography Reshaped?

The topography, or surface of the Earth, is constantly changing shape due to many powerful forces. In this lesson, we will learn about some of the amazing changes that occur on Earth due to the processes of weathering, erosion, and deposition.

What is Chemical Weathering? - Definition, Process & Examples

7. 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.

Mechanical Weathering: Definition, Process, Types & Examples

8. 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.

Factors that Affect the Rate of Weathering

9. Factors that Affect the Rate of Weathering

Weathering is the process that breaks down rocks into smaller pieces. The rate at which rock weathers depends on certain factors. Learn how factors, such as exposure to the atmosphere, the composition of rock and climate affect the rate of weathering.

Characteristics of Shorelines & Beaches

10. Characteristics of Shorelines & Beaches

Shorelines and beaches are constantly changing due to forces, such as waves, winds and currents. Learn about characteristics of shorelines, including headlands, bays, beach berms, sand dunes, spits, tombolos, barrier islands and lagoons.

How Rivers and Streams Affect the Earth's Surface

11. How Rivers and Streams Affect the Earth's Surface

Rivers and streams are powerful, ever-changing systems that can alter the surface of the Earth. While they share many similar features, they can be vastly different. In this lesson, we will learn how rivers and streams form, transport sediment, and flood.

Effect of Erosion and Deposition on Landforms

12. 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.

The Effects of Coastal Erosion on Shoreline Features

13. The Effects of Coastal Erosion on Shoreline Features

Shorelines constantly change due to the pounding of waves that erode coastal structures. Learn about shoreline features that are formed through coastal erosion, such as wave-cut cliffs, wave-cut platforms, sea arches and sea stacks.

Ground and Surface Water: Effects On Landscapes

14. 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.

Base Level of a Stream: Definition & Effect on Erosion

15. Base Level of a Stream: Definition & Effect on Erosion

Water stops flowing when it reaches its lowest level; this is called the base level. Learn about the base level of a stream, how it affects erosion, and some examples of local base levels, including lakes, dams and waterfalls.

What is Soil? - Definition, Structure & Types

16. What is Soil? - Definition, Structure & Types

Soil is the material found on the surface of the earth that is composed of organic and inorganic material. Soil varies due to its structure and composition. Learn about the different types of soil and soil structures in this video lesson.
