About This Chapter

Refresh your memory of the differences between highly developed countries and others with this chapter's study resources. Here, you can watch 5-minute video lessons and self-assessments on the effects of a population on the environment for the ORELA Middle Grades Social Science exam.

Effects of Population on the Environment: ORELA Middle Grades Social Science - Chapter Summary

Do you remember the definitions of population density and demographic transition? If you do not, this chapter full of video lessons can help you remember. You can also take our end-of-lesson quizzes to test yourself on Thomas Malthus' theory and areas which are sparsely populated. By the time you have finished this chapter, you will be able to answer exam questions based on the following:

  • Environment and ecosystems
  • Influences of population size and its impact
  • Definition of biotic potential, population density, and demographic transition
  • Human population growth's history
  • Thomas Malthus' theory
  • Global population concentration
  • Areas that are sparsely populated
  • Economic inequality
  • Poverty and sustainability
  • Highly developed countries
  • Population distribution of rural and urban areas
  • Over-consumption

You can always get additional practice answering test-related questions by taking the chapter and final exams. Studying on the go is made easy with this chapter, because you can print out the quiz worksheets and answers. In the video transcripts, you will find the vocabulary words in bold.

17 Lessons in Chapter 42: Effects of Population on the Environment - ORELA Middle Grades Social Science
The Environment, Levels of Ecology and Ecosystems

1. The Environment, Levels of Ecology and Ecosystems

Do you know the difference between an environment and an ecosystem? In this lesson, you'll find out what makes an environment, and what makes an ecosystem. You'll also learn what ecology is and some of the ways that scientists study ecology using organisms, populations, communities, ecosystems and even the entire biosphere.

Ecosystems, Habitats and Ecological Niches

2. Ecosystems, Habitats and Ecological Niches

Check out this video lesson to understand the many complex aspects of an ecosystem. See how animals live in habitats and survive amongst their surroundings.

The Human Population: Factors that Affect Population Size

3. The Human Population: Factors that Affect Population Size

The human population is constantly changing. In this lesson, we will explore the factors that cause increases and decreases in the human population, including births, deaths, immigration, and emigration.

Biotic Potential and Carrying Capacity of a Population

4. Biotic Potential and Carrying Capacity of a Population

When you look around, you can see a number of different individuals and species. In this lesson, we will explore the factors that control and define how many organisms can really inhabit a particular ecosystem or habitat.

The History of Human Population Growth and Carrying Capacity

5. The History of Human Population Growth and Carrying Capacity

Most of us are used to the current size of the human population but it was not always this large. In this lesson, we will explore the history of human population growth and the future of its growth.

Thomas Malthus' Theory of Human Population Growth

6. Thomas Malthus' Theory of Human Population Growth

In this lesson, we will explore the ideas of Thomas Malthus and his predictions for the growth of the human population. We will also investigate if his predictions have come true or not.

Population Density Around the World

7. Population Density Around the World

This lesson will explain the concept of population density. In doing this, it will discuss sparsely versus densely populated areas. It will also identify the primary and secondary population clusters of the world.

Sparsely Populated World Regions

8. Sparsely Populated World Regions

This lesson will explain the reasons for a sparse population distribution. In doing so, it will highlight the factors of relief, natural resources, climate, and political and economic stability. It will also give examples of sparsely populated areas.

What Is Population Density? - Definition & Measurements

9. What Is Population Density? - Definition & Measurements

This lesson will seek to explain the concept of population density. It will focus on three specific measurements of density. They are arithmetic, physiological, and agricultural density.

Economic Inequality: Differences in Developed and Developing Nations

10. Economic Inequality: Differences in Developed and Developing Nations

Not everyone has the same house, the same car, or makes the same amount of money. In this lesson, we will explore the concept of economic inequality and investigate what characteristics make a nation developed or developing.

Poverty, Carrying Capacity, Population Growth & Sustainability

11. Poverty, Carrying Capacity, Population Growth & Sustainability

Worldwide poverty is a large issue. In this lesson, we will explore how poverty influences population growth rates and how these things relate to carrying capacity and global sustainability.

What Is Demographic Transition? - Definition & Stages

12. What Is Demographic Transition? - Definition & Stages

There are many differences between non-industrial and industrial countries. In this lesson, we will explore the concept of demographic transition and the stages that guide a country through its changes into an industrial country.

Population Characteristics of Highly Developed & Developing Countries

13. Population Characteristics of Highly Developed & Developing Countries

The population of a country is based on many factors. In this lesson, we will explore several important factors that differ between developed and developing countries.

Population Distribution: Rural vs. Urban Areas

14. Population Distribution: Rural vs. Urban Areas

The distribution of people varies depending in the type of location. In this lesson, we will explore how people are distributed between rural and urban areas and how these populations have changed over time.

Population Size: Impacts on Resource Consumption

15. Population Size: Impacts on Resource Consumption

What are the things you need to survive? Humans all need resources, and in this lesson, we will discuss how the growth of the human population is influencing the natural resources we rely on.

Urban Population Growth and Compact Development

16. Urban Population Growth and Compact Development

The population growth rates in urban areas are on the rise, and as more people move to cities, there are many problems that can occur. We will discuss several issues associated with this growth and also a potential method for minimizing the effects.

Overpopulation vs. Overconsumption

17. Overpopulation vs. Overconsumption

How many people can the Earth support? In this lesson, we will explore population growth and some of the concerns associated with this growth, including overpopulation and overconsumption.
