About This Chapter
Water Systems - Chapter Summary
The lessons in this chapter cover the basic properties of different types of water, including ocean and glacial water. You can learn how the processes of evaporation and transpiration play a role in the hydrologic cycle. You'll also discover the effect of ocean circulation on climate patterns. Lessons are devoted to the results of glacial erosion and deposition.
The chapter examines the role of spring and groundwater systems in retaining water and nutrients. The function of water throughout various weather conditions is explored, including how water contributes to cloud formation, precipitation and humidity. Later lessons list some of the tools and technologies used to forecast weather patterns. The chapter closes with instruction on how to interpret weather maps. When you finish this chapter, you should have an understanding of the following key topics:
- Basic properties of water
- Evaporation and transpiration as part of the hydrologic cycle
- Properties of ocean water
- Glacial erosion and deposition
- Upwelling of nutrients
- Role of spring and groundwater systems
- Humidity, cloud formation and precipitation
- Technologies and tools used to collect and forecast weather
- Interpretation of weather maps
We provide concise video lessons taught by experienced instructors in the field. Lessons come with self-assessment quizzes and transcripts, so you can check your learning as you complete the chapter. You can also use video tags to quickly locate certain information.
1. Properties of Water
Why does ice float? Why can water rise on its own against gravity in a small tube? Find out how these mysterious properties of water can be explained by hydrogen bonds.
2. What Are the Properties of Water? - Unique Properties that Support Life on Earth
In this video lesson you will learn about water and its unique properties. You will also develop an understanding of how these properties make life as we know it possible.
3. 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.
4. 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.
5. 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.
6. What Are Glaciers? - Definition, Types & Processes
Learn about the two major types of glaciers: continental and alpine glaciers. These glaciers shape the landscape around them and affect our everyday lives, even if the nearest glacier is thousands of miles away.
7. What is Humidity? - Definition, Measurements & Effects
Humidity is an important aspect of the atmosphere because it affects both weather and climate. In this video lesson you will learn about the different types of humidity and understand how temperature affects water vapor in the air.
8. What is Cloud Formation? - Definition, Types & Process
There are many different types of clouds that form in the sky. In this video lesson you will learn about how clouds form, as well as the different types of clouds and how they are classified.
9. What is Precipitation? - Definition, Types & Formation
Precipitation comes in many forms, but it all comes from the same general process. In this video lesson you will identify different types of precipitation, as well as how precipitation forms in the atmosphere from condensation.
