Earth's Natural Materials & Processes - Chapter Summary

This chapter contains video lessons that make it easy to understand Earth's natural materials and processes. The characteristics of fossils, Earth's materials and the ways they sustain animal and plant life are just a few of the topics covered here. You'll also study the Earth's atmosphere, fossil fuels, greenhouse gases and global warming. This chapter is designed to assist you as you work to achieve these objectives:

  • Discuss the impacts of humans on the environment
  • Detail the effects of natural phenomena on the Earth's climate
  • Differentiate between renewable and non-renewable resources
  • Define alternative energy and its sources
  • Explain the conservation of mass and changes in the rock cycle
  • Outline the components of the water cycle
  • Identify the nitrogen cycle and the carbon cycle
  • Describe the internal and external forces that shape the Earth's surface

When you work through this chapter, you'll have access to our informative video lessons and self-assessment quizzes at any time on your mobile phone, tablet or computer. Watch an entire video lesson all the way through or use the video tabs feature to skip ahead to the section you'd like to see.

Earth's Materials: Minerals, Rocks, Soil & Water

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.

Fossil: Definition, Types, Characteristics & Examples

2. 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.

How Earth Materials Sustain Animal and Plant Life

3. 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.

The Atmosphere on Earth

4. The Atmosphere on Earth

This lesson describes the evolution of the Earth's atmosphere, from its ancient past to the present day to how it's being changed by humans today. You'll learn about how outgassing, photosynthesis, and oceans all played a role in its formation, what air is composed of, and the real effect of human pollution on our changing atmosphere.

Fossil Fuels, Greenhouse Gases, and Global Warming

5. Fossil Fuels, Greenhouse Gases, and Global Warming

In this video lesson, you'll learn what roles fossil fuels and greenhouse gases play in global warming, as well as what life on Earth can expect due to rising carbon dioxide levels within Earth's atmosphere.

Human Impacts on the Environment

6. Human Impacts on the Environment

The human population continues to grow, but the size of Earth and the resources available for our use are limited. Humans greatly impact the world around them, and our actions can and often do have dramatic and long-lasting consequences.

The Impact of Natural Phenomena on Earth's Climate

7. The Impact of Natural Phenomena on Earth's Climate

Natural phenomena can have a great impact on the earth's weather and climate. In this lesson, we will explore the different types of phenomena that affect our climate and their effects.

Renewable & Non-Renewable Resources: Definition & Differences

8. Renewable & Non-Renewable Resources: Definition & Differences

We use a variety of Earth's resources, but not all of them will be around forever. This lesson explains the difference between resources that can be regenerated for our use and those that are gone after they are used once.

What is Alternative Energy? - Definition & Sources

9. What is Alternative Energy? - Definition & Sources

What is alternative energy? Alternative to what and why are people looking for alternatives anyway? Learn the answers to those questions in this lesson.

The Rock Cycle: Conservation of Mass & Changes

10. The Rock Cycle: Conservation of Mass & Changes

In this lesson, we'll review the rock cycle. Then, we'll get into how the law of conservation of mass in physics applies to the rock cycle. As we do this, we'll also cover the physical and chemical changes occurring in the rock cycle.

The Water Cycle: Precipitation, Condensation, and Evaporation

11. 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.

Cycles of Matter: The Nitrogen Cycle and the Carbon Cycle

12. Cycles of Matter: The Nitrogen Cycle and the Carbon Cycle

Matter is constantly cycled between living and nonliving parts of the environment. Processes like photosynthesis and nitrogen fixation allow the carbon and nitrogen cycles to regenerate needed substances by recycling Earth's atoms.

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

13. 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.
