2.  Discuss the earth-atmosphere interface. Include in your discussion what you learned more about weathering, karst landscapes, and mass movement; river systems. Also discuss how geoscientists study the planet to come to the conclusions they do. Finally discuss why you think it is significant to study these topics.

Note: This question asks you to summarize chapters 14 and 15. Chapter 14 (“weathering, karst landscapes, and mass movement”) covers physical vs. chemical weathering, karst topography, and mass movements of earth materials. Chapter 15 (“River Systems”) covers drainage basin models, stream concepts (gradient, base level, velocity/depth/width/discharge), landforms, and flooding.


I. Overview

II. Weathering, Karst Landscapes, and Mass Movement

·        Describe how landforms are studied; include equilibrium models

·        Define weathering; explain what parent rock is and the importance of fractures/joints

·        Describe processes associated with physical weathering

·        Describe processes associated with chemical weathering

·        Review the processes and features associated with karst topography

·        Discuss the various types of mass movement, their speeds, and moisture content

III. River Systems

·        Discuss drainage basin models; give examples to show a deeper understanding

·        Discuss stream concepts (gradient, base level, velocity/depth/width/discharge)

·        Explain the processes associated with stream erosion and deposition

·        Describe some landforms associated with streams; give examples

·        Discuss flooding and flood probabilities

IV. Science of Geography

·        Define Physical Geography

·        Describe modern geoscience techniques: GPS, remote sensing (RS), and GIS

·        Explain how these tools are used in geographic analysis (give examples)

V. Significance

·        Discuss why it is important to study the topics above

·        Give examples to show a deeper level of understanding

VI. Summary

·        Include a summary at the end to reinforce the concepts discussed above (see online examples)
