1. 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.
2. 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.
3. 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.
4. 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.
5. What Is Eutrophication? - Definition, Causes & Effects
Ever heard the phrase, 'too much of a good thing?' Eutrophication is a good example of this. When aquatic systems have an overabundance of nutrients, the entire system suffers and can ultimately become unlivable.
6. 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.
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. Great Lakes Water Issues: Pollution & Invasive Species
Making up the largest freshwater system on Earth, the Great Lakes are an impressive feature. But there are also great issues: those of pollution and invasive species.
