1. Ground and Surface Water: Effects On Landscapes
In this lesson, you will learn how groundwater and surface water form features on Earth and cause changes in landscapes. You will also learn about the different types of features formed by each type of water.
2. 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.
3. Water Quality & Water Supply: Definition & Purpose
Learn the difference between water quality and supply, including the factors that make up good quality of water, and why it's important for humans and other animals alike. Check the quality of your learning by finishing with a quiz.
4. 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.
5. Pollution: Physical, Chemical & Biological
Pollution is the presence of unwanted substances in an environment. It is often the result of human interference. Learn about physical, chemical and biological pollutants and see examples of each.
6. What is Thermal Pollution?
Pollution is one of the greatest threats against our environment. We often overlook the fact that pollution isn't simply smoke and industrial waste. In this lesson, we'll take a look at a lesser-known type of pollution: thermal pollution.
7. Human Causes of Eutrophication
Eutrophication occurs when a body of water becomes overly enriched with nutrients. While this can happen naturally, accelerated eutrophication is typically the result of human activities. Learn about the human causes of eutrophication.
8. 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.
9. 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.
10. 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.
11. 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.
12. 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.
