About This Chapter
Water Balance - Chapter Summary
Water, or the lack of it, is a major influence on our planet and our lives. In the lessons in this chapter, you will look at the water cycle and what it accomplishes. Our knowledgeable instructors conduct video lessons that cover topics including the distribution of water on Earth, runoff and precipitation. Each lesson covers some aspect of the hydrologic cycle and how it works. The quizzes that follow each lesson will give you immediate feedback so you know what your strengths and weaknesses are. By the end of this chapter, you should be able to:
- Describe the processes of the water cycle
- Analyze water distribution on our planet
- Detail the pros and cons of solar power
- Explain the relationship between evaporation and transpiration
- Define runoff and infiltration
- Use vocabulary words related to the water cycle
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. The Distribution of Water on Earth
Water covers most of Earth but in a variety of forms. In this video lesson you will learn about how water is distributed on Earth, though you may be surprised to find out just how little of it we can access!
3. What is Solar Power? - Uses, Advantages & Disadvantages
The sun provides us with a constant energy source. In this video lesson, you'll learn how we can harness solar power from the sun. We'll also take a look at the pros and cons of this renewable energy resource.
4. How Evaporation & Transpiration Contribute to the Hydrologic Cycle
Evaporation and transpiration are important components of the water cycle, and while they are the same process they arise from different sources. In this video lesson you will learn about these two parts of the cycle and how they contribute to the overall movement of water on Earth.
5. Runoff & Infiltration: Definition & Process
When water falls to the ground as precipitation, it can either fill the spaces in the soil below ground or run across the surface. In this video lesson, you will learn about the processes of infiltration and runoff, and how they are an important part of the water cycle on Earth.
