About This Chapter
Atmospheric Moisture - Chapter Summary and Learning Objectives
Explore how water continuously moves on, above and below Earth's surface through this chapter on atmospheric moisture. You'll learn about the processes of the hydrologic cycle (also called the water cycle), including evaporation, condensation and precipitation, and find out how atmospheric moisture affects the climate.
By the end of this chapter, you should be able to:
- Identify factors that surround saturation, including condensation and ice nuclei.
- Explain the first and second laws of thermodynamics.
- Differentiate between dry and moist adiabatic lapse rates.
- Describe the typology and distribution of dew, frost and fog.

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. 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.
3. 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.
4. First Law of Thermodynamics: Law of Conservation of Energy
This video describes the first law of thermodynamics. Several examples of the application of this law are discussed. The significance of the law and its practical application are discussed as well.
5. Second Law of Thermodynamics: Entropy and Systems
In this lesson, we'll learn about the second law of thermodynamics. By studying this law, you'll understand how energy works and why we're all moving towards eventual chaos and disorder.
6. Measures of Water Vapor Content
When you think of all of the things you measure, water vapor probably doesn't come to mind. This lesson will explore different ways to measure water vapor in the air!
7. Causes of Saturation & Saturation Processes
Have you ever wondered what happens to water vapor in the air around you? This lesson will explore saturation, or what happens when the air can't hold anymore water.
8. Adiabatic vs. Diabatic Processes: Cloud Formation
Why does air cool? And how is this related to cloud formation? This lesson will explore the adiabatic and diabatic processes, which are a couple of ways the air can cool, and then relate this to cloud formation.
9. Types of Atmospheric Lapse Rates
Have you ever wondered what happens to air as it rises? Well, you've come to the right place. This lesson examines lapse rates, or the speed at which air cools as it rises in the atmosphere.
10. Types of Condensation
There is evidence of condensation all around you, even if you don't know it! This lesson will explore the different types of condensation, including dew and fog.
11. Formation & Dissipation of Cloud Droplets
Have you ever wondered why a cloud forms? Well, you've come to the right place! This lesson will explain why clouds form and will also examine why they disappear.
12. The Effect of Atmospheric Moisture on Climate Variability
You might not think water vapor in the air can impact the climate, but it can. This lesson will explore how water vapor and climate are related and will also explain how climate change is impacting the amount of water vapor in the air.
