About This Chapter
OAE Integrated Science: Chemical Cycling & Human Activities - Chapter Summary
The lessons in this chapter will describe the three main chemical cycles: carbon, phosphorus, and nitrogen. They will explain the cycles' various steps and their relationships to different natural phenomena such as weather and global warming. By the end of the chapter, you will have reviewed:
- The two types of natural resources
- Biogeochemical cycling
- Fossil fuels and global warming
- Invasive species and their impact on ecosystems
- The nitrogen, carbon, and phosphorus cycles
- The definition of conversation biology
Each lesson ends with a series of short questions. These questions are in the same format as those on your upcoming exam. By the end of the chapter, you will have sharpened your test-taking skills and learned how to effectively and quickly answer questions on chemical cycling and human activities.
OAE Integrated Science: Chemical Cycling & Human Activities Chapter Objectives
The OAE Integrated Science exam is a 3-hour computer-based test with 150 multiple-choice questions. The exam assesses your knowledge of four domains: the general nature of science, Earth and space science, life science, and physical science. This Chemical Cycling & Human Activities chapter connects to the Earth and space science domain. About 19% of your overall OAE - Integrated science score will connect to this earth science domain.
The earth science domain has a range of tested competencies. These tested competencies include the geology and history of the Earth, characteristics of weather and climate, and the characteristics of the solar system. This chapter about the cycling of chemicals and our influence on these cycles neatly fits into two of these areas. The chemical cycles tie into the geology of our Earth and they also affect our weather patterns. This single chapter will help you prepare for many different types of questions.
1. Biogeochemical Cycling and the Phosphorus Cycle
In this video lesson, we'll take a look at how elements large and small use other elements to grow. This is achieved through cycles. We'll look at macronutrients, trace elements and the biogeochemical and phosphorous cycles.
2. The Nitrogen Cycle, Acid Rain and Fossil Fuels
Do you know the difference between nitrite and nitrate? Do you have any clue how all the nitrogen in the atmosphere becomes usable? If you can't answer these questions, then you need to watch this lesson on the nitrogen cycle.
3. The Carbon Cycle and Long-Term Carbon Storage
All living organisms have a role in the carbon cycle. Do you know you understand how humans, animals and plants use carbon? This lesson will introduce you to the carbon cycle and explain how it functions on a global scale.
4. 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.
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.
6. Conservation Biology, Habitat Fragmentation, and Metapopulations
It's becoming harder to conserve large, unbroken tracts of wilderness. Is there another way for conservation biologists to ensure the survival of a species? In this lesson, you'll learn about habitat fragmentation and metapopulations.
7. How Introduced and Invasive Species Alter Ecological Balance
What happens to your block when a new neighbor moves in? Something changes, right? Now think about that on an ecological scale: what happens to an environment when a new SPECIES moves in?
