- 3.1: Lesson 3 Introduction
- In this lesson, we will return to the amazing properties of water and how those properties influence Earth surface processes.
- 3.2: Ice, Water, and Vapor
- We will first examine water as a molecule, and then explore the implications of water's molecular structure for its physical behavior and its importance as a "universal solvent."
- 3.3: Salt as a Commodity
- We won't dwell too much on salt as a commodity here, but it is an interesting topic for students because salt has played such an important role in human history.
- 3.4: Latent Heat and Heat Capacity
- These are the relevant physical properties of water and their significance
- 3.5: Water as the Universal Solvent
- As indicated in previous sections, the polar water molecule allows water molecules to form bonds with one another.
- 3.6: Why the Sea is Bitter
- Rachel Carson provided this poetic statement about the evolution of seawater chemistry over time in her book, first written in 1950.
- 3.7: It's All About Cycles
- Yes, water cycles (the hydrologic cycle) and geochemical cycles (tracing the paths of various elements to and from seawater).
- 3.8: Geochemical Residence Time
- Every one of these elements is present at some concentration in seawater.
- 3.9: Seawater Properties Activity
- Is the Chemical Composition of Seawater Constant? Do All Elements Behave Alike?
- 3.10: Additional Resources
- Various Web sites with links to resources aimed at teachers and students:
- 3.11: Summary and Final Tasks
- Reminder - Complete all of the lesson tasks!
