About This Chapter
The Hydrosphere - Chapter Summary
Go over the properties and importance of oceans, rivers, streams and groundwater with these short but informative videos and text lessons. The lessons define key terms and processes relating to the hydrosphere and hydrologic cycle.
You will come to understand water types and processes as well as the effect of these processes on Earth's surface and climate. After reviewing this chapter, you should be able to:
- Explain the distribution of different types of water on the Earth's surface
- Define the water cycle and the hydrologic cycle
- Discuss ocean water properties and circulation
- List the effects of rivers and streams on the Earth's surface
- Describe groundwater and surface water and their effects on the Earth
- Detail the processes of evaporation and transpiration
- Summarize the process of runoff and infiltration
Our engaging lessons provide illustrations and examples to help you fully understand the concepts discussed. You can choose to print lesson transcripts to use as handy reference guides and even send questions directly to the instructors. Self-assessment quizzes can be used to determine what you have learned from the lessons.
1. 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!
2. Properties of Ocean Water
Ocean waters are salty and contain minerals and dissolved gases. They also have a high heat capacity and vary in density depending on temperature and salinity. Learn more about the unique chemical and physical properties of ocean water.
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. Rivers: Definition & Explanation
Explore rivers and how they develop from small streams to swiftly flowing rapids. Learn about how rivers shape the land around them, creating canyons, flood plains and deltas.
5. 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.
6. What is Groundwater? - Definition & Explanation
Groundwater accounts for up to 20% of all the fresh water on Earth. This lesson will explain what ground water is and its important aspects. Once you've finished the lesson, test your understanding with a quiz.
7. 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.
8. 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.
9. The Hydrologic Cycle: Definition, Process & Diagram
The hydrologic, or water, cycle describes the storage and movement of all water on Earth. This lesson will cover the different reservoirs where water can be stored and how it moves between them.
10. 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.
11. 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.
