Ch 28: Water Cycle & Balance

About This Chapter

Watch our video lessons to review facts about how water is distributed and the cycle that keeps it in constant use. Learn about solar power, evaporation, the composition of water and tools for analyzing hydrologic systems.

Water Cycle & Balance - Chapter Summary

Use these videos to refresh your understanding of how water is distributed on Earth. You'll look at uses for solar power and see how the hydrologic cycle works. Water's chemistry is the topic of one lesson, and our instructors explain how data about water is gathered and analyzed. When you've finished these lessons, you should be prepared to:

  • Explain precipitation, condensation and evaporation
  • Name advantages and disadvantages for using solar power
  • List ways that evaporation and transpiration function in the hydrologic cycle
  • Analyze the composition and attributes of fresh, salt and brackish water
  • Describe the procedures and tools used to collect and analyze date about hydrologic systems

Our video lessons are developed and led by expert instructors who keep the learning fun. The lessons average about five minutes in length, and you can watch on a computer or mobile device, as your schedule allows. Afterwards, assess your knowledge by taking a multiple-choice quiz. Each lesson contains video tags so you can easily return to key topics that require further review without having to re-watch the entire lesson.

The Water Cycle: Precipitation, Condensation, and Evaporation

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.

The Distribution of Water on Earth

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!

What is Solar Power? - Uses, Advantages & Disadvantages

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.

How Evaporation & Transpiration Contribute to the Hydrologic Cycle

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.

Chemical Composition & Physical Attributes of Fresh, Brackish & Salt Water

5. Chemical Composition & Physical Attributes of Fresh, Brackish & Salt Water

Discover the differences between fresh, brackish, and saltwater. Learn about their chemical and physical features. Afterward, see how well you know the differences by taking a quiz.
