Ch 6: Atmospheric Moisture

Learn about atmospheric moisture through the video lessons in this chapter. Each lesson is accompanied by a short multiple-choice quiz you can use to check your understanding of humidity, the water cycle, atmospheric lapse rates and more.

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.
