3.  Discuss the earth-atmosphere interface. Include in your discussion what you learned more about oceans, coastal systems, and wind processes; and glacial and periglacial landscapes. 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 16 and 17. Chapter 16 (“Oceans, Coastal Systems, and Wind Processes”) covers composition and structure of the ocean, wave motion and coastal landforms, barrier beaches and islands and hazards, coral reefs and coastal wetlands, and sand dunes. Chapter 17 (“Glacial and Periglacial Processes”) covers glacier formation, alpine vs. continental glaciers, glacial movement, glacial landforms, permafrost, ice ages, and current changes in polar regions.


I. Overview

II. Oceans, Coastal Systems, and Wind Processes

·        Describe chemical composition and physical structure of the ocean

·        Identify components of the coastal environment, define mean sea level, and explain the actions of the tides

·        Describe wave motion and explain coastal straightening and coastal landforms

·        Describe barrier beaches and islands and their hazards to humans

·        Describe the nature of coral reefs and coastal wetlands and human impacts on them

·        Describe eolian transport of dust and sand, and discuss eolian erosion and the resultant landforms

·        Explain the formation of sand dunes

III. Glacial and Periglacial Processes

·        Explain how snow becomes ice to form a glacier

·        Differentiate between alpine and continental glaciers and describe ice caps and ice fields

·        Describe characteristic landforms created by glaciers

·        Discuss permafrost and explain several periglacial processes

·        Describe landscapes formed by ice-age glaciers and list changes occurring today at the poles

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)
