About This Chapter
Earth Materials - Chapter Summary and Learning Objectives
Whether you need a quick refresher on the types and properties of earth materials or want to get a firm understanding of the basics before moving on to additional lessons on the rock cycle, mountain building or weathering and erosion, take advantage of our instructors' expertise by watching the videos included in this chapter. You can learn the differences between rocks and minerals or discover the importance of soil in the water cycle. The significance of other materials, such as precious metals, in our everyday lives is also discussed.
When you're ready, there are also short self-assessment quizzes at the end of each lesson that you can use to gauge your understanding of the material. By the end of this chapter, you should be able to do the following:
- Describe the life cycles of various types of earth materials
- Identify differences between metals and precious rocks
- Elaborate on how these earth materials sustain life
|Earth's Materials: Minerals, Rocks, Soil & Water||Identifies types of earth material and explores the origins of minerals, rocks, soil and water.|
|How Earth Materials Sustain Animal and Plant Life||Explains the ways in which natural earth materials provide the resources necessary to sustain plant and animal life.|

1. Earth's Materials: Minerals, Rocks, Soil & Water
Although the earth is a very complex system, there are only four main components of Earth that are the building blocks of life. These components are referred to as Earth's materials and include minerals, rocks, soil and water.
2. How Earth Materials Sustain Animal and Plant Life
The earth can be a very complex system with many different interacting parts. But, at its base, it is made up of four main materials that make life on Earth possible for both plants and animals.
3. Other Earth Materials: Metals and Precious Rocks
Our planet contains a variety of natural resources that we rely on to survive. Some of these resources, including metals and precious rocks, are less common than others and serve unique functions.
