About This Chapter
Water on Earth - Chapter Summary
Complete this online study guide chapter to improve your knowledge of water on the planet Earth. The chapter is broken into short and expertly taught lessons that lay out the steps of the water cycle, the distribution of water on Earth, the effects of waves on erosion, the causes/effects of tides and the formation of different types of sea ice. You'll also take a look at the groundwater system and patterns of ocean circulation. By the end of the chapter, you should be fully equipped to:
- Evaluate the processes of precipitation, condensation and evaporation in the water cycle
- Understand how water is distributed on Earth
- Describe ocean circulation patterns
- Compare different types of waves and their effects on erosion
- Recognize the causes and effects of tides
- Determine how the Earth's surface is affected by rivers and streams
- Discuss the geological role of the groundwater system
- Explain how sea ice is formed
Each lesson comes with a short quiz that can help you remember these concepts. Be sure to take the chapter exam and use the Ask the Expert feature if you have any questions. You can study offline by printing the lesson transcripts, or you can watch the lessons online using any computer or mobile device.
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. Ocean Circulation: Patterns & Effect on Climate
The ocean waters are always in motion and as they travel around the globe they carry and distribute heat, which affects the global climate. Learn about the ocean circulation patterns and how they impact the climate.
4. Waves: Types, Features & Effect on Erosion
There are different types of ocean waves, including wind waves, tsunamis and tidal waves. Learn the features of waves and how their erosive effect creates the unique features found on the shoreline.
5. What Are Tides? - Causes & Effects
Tides rise and fall under the influence of the gravitational pull of the moon and sun. Learn about different tides, why they are predictable and their effects on coastal regions of the world.
6. How Rivers and Streams Affect the Earth's Surface
Rivers and streams are powerful, ever-changing systems that can alter the surface of the Earth. While they share many similar features, they can be vastly different. In this lesson, we will learn how rivers and streams form, transport sediment, and flood.
7. Groundwater System: Definition & Geological Role
Surprisingly, most of Earth's liquid freshwater is not where you might think! In this video lesson, you will learn about groundwater, as well as the important roles it plays in sustaining life and shaping Earth.
8. Sea Ice: Formation & Types
In this lesson we'll be learning about the different types of sea ice that cover the North and South poles. By the end of the lesson, you'll be able to explain what polar ice caps, icebergs, and glaciers are and how they form.
