About This Chapter
MTLE Middle Level Science: Human Interactions with Earth Systems - Chapter Summary
Use this chapter to review the different spheres of the Earth and learn about the impact that we, as humans, have on our environment. As you get ready to pass the MTLE Middle Level Science exam, you will explore topics such as environmental health, the four spheres of the earth and more. Once you complete all the lessons, you will be ready to:
- Explain the effects of humans on the environment
- Understand the interactions of the Earth's spheres
- Identify the composition of the Earth's atmosphere and lithosphere
- Define the hydrosphere
- Discuss the sources and types of water and air pollution
- Describe human activities that increase the risk of natural disasters
The lessons in this chapter have been designed to allow you to review the specific material you may encounter on the exam. You will find a short video in each lesson that helps to illustrate the information. A transcript of the video is included for text-based learning. You can take a self-assessment quiz at the end of each chapter to apply what you've studied and practice for the exam.
1. What Is Environmental Health? Definition, Types & Sources
In this video lesson, you will learn about environmental health. You will also learn about threats to environmental health and how to distinguish between different categories of environmental hazards.
2. 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.
3. 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.
4. Interactions of Earth's Spheres: Purpose and Examples
The four spheres of Earth drive all of its processes and support life on our unique planet. In this video lesson, you will see examples of how Earth's spheres interact with each other to form an overall complex and connected system.
5. 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.
6. The Lithosphere: Definition & Composition
The lithosphere is where we live. It is also the source of many geologic events that affect us. In this lesson, you will learn more about this important part of our planet.
7. What is the Hydrosphere? - Definition & Examples
Have you ever wondered how much water is on Earth? In this lesson, we will trace how water travels around Earth. You will learn the definition of a hydrosphere and take a quiz to test your knowledge.
8. Water Pollution: Definition, Types, and Sources
In this lesson, you will learn about the different types and sources of water pollution. You will gain an understanding of both surface water and groundwater pollution and the similarities and differences between them.
9. What Is Air Pollution? - Definition, Sources & Types
In this video lesson, you will learn about the sources and types of air pollution. You will be able to identify the six classes of air pollutants identified by the Environmental Protection Agency and the Clean Air Act of 1970.
10. Human Activities That Increase the Risk of Natural Disasters
Although we typically think of natural disasters as being caused by nature, today we'll be learning how humans influence both the frequency and intensity of these events.
