Students will review:
In this chapter, you'll learn the answers to questions including:
- What are the unique chemical properties of water?
- What stages occur during the carbon and nitrogen cycles?
- How can drip irrigation or other methods be used to conserve water?
- What are some advantages and disadvantages to dams and reservoirs?
- What are some causes and sources of water pollution?

1. 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.
2. 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.
3. What Are the Properties of Water? - Unique Properties that Support Life on Earth
In this video lesson you will learn about water and its unique properties. You will also develop an understanding of how these properties make life as we know it possible.
4. Water Resource Issues: Activities Affecting the Water Supply
This video lesson describes water resources issues such as aquifer depletion, overdrawing surface waters and salinization of irrigated soil. You will also learn about the impacts of activities affecting water resources.
5. Aquifer Depletion and Overdrawing of Surface Waters: Effects on Water Resources
This video lesson describes the effects of overuse on two major water resources in the U.S.: the depletion of the Ogallala Aquifer and the overdrawing of the Colorado River.
6. Water Conservation: How Water Management Can Lead to Sustainable Use
In this video lesson you will learn about the importance of water conservation. You will also learn about the two ways freshwater is used, and how proper water use can lead to sustainability in agriculture, homes, and manufacturing.
7. Water Storage: The Pros and Cons of Dams & Reservoirs
In this lesson, you will contrast the benefits and drawback of water storage. You will learn about how and why water is stored and how this affects the surrounding ecosystems and human communities.
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. Water Treatment: Improving Water Quality
In this lesson, you will learn how water is purified for drinking, and how wastewater is treated before being put back into the environment. You will also learn about water purification issues in developing countries.
10. The Clean Water Act & Safe Drinking Water Act: Legislation for Clean Water
In this lesson, you will learn about the Clean Water Act of 1972 and the Safe Drinking Water Act of 1974. You'll discover how both laws help keep our waters free of pollution and safe for everyday use.
11. Aquifer: Definition, Types & Facts
Did you know that when you drink water from a well you may be drinking ancient water? In this lesson you will learn the definition of an aquifer and learn why aquifers are important. In addition, you will learn how humans have impacted aquifers. At the end, test your knowledge with a quiz.
12. What is a Reservoir? - Definition, Formation & Characteristics
In this lesson, we will review what a reservoir is and the different ways it can be formed. We'll also review characteristics reservoirs have in common, uses for reservoirs, and problems they can create.
13. Water Pollution in Africa: Causes and Effects
Water pollution is a global problem, especially in developing regions of Africa. In this lesson, learn about the lead contributors to water pollution in Africa and what is being done about the problem.
14. Surface Tension: Definition, Causes, Measurement & Formula
In this lesson, we will look at a couple examples of surface tension. We will learn the definition of surface tension, what causes it, how to measure surface tension, and how to use the surface tension formula.
15. What is Potassium Permanganate? - Structure, Uses & Formula
Potassium permanganate is something we don't hear about quite often, but it is a very useful chemical compound that we probably have encountered and used before. In this lesson, we will discuss the structure, formula, and uses of potassium permanganate.
16. Alkalinity: Definition & Calculation
This lesson looks at the properties of an alkaline solution. Alkalinity and pH are defined, and the calculations for finding the pH of a solution are laid out.
