Name _________________________________________________ Chapter 19: Investigation Worksheet To complete this worksheet, see the instructions in the textbook (Chapter 19 Investigation). Table 1: Geologic Features of an Alien World Table 2. Relative Ages of Regions and Features Observations: Observe the image below, and interpret where boundaries are located between regions that have different geologic characteristics. Your Chapter 19 Investigation shows photographs for each region, which may help you decide what features characterize each region. Draw in the boundaries between these regions. Using all the information, number the events in order from oldest (1) to youngest (7). Note that the sedimentary terrain (S) fills, and so is younger than, the valleys (V). Also, in one location (too small to see on the globe), rocks of the mountains are covered by deposits from the valleys. Order (1 for oldest to 7 for youngest) Terrain or Feature ____ Western Terrain (W) and Eastern Terrain (E) ____ Dark Terrain (D) ____ Chasm (C) ____ Polar Ice (P) ____ Sedimentary Terrain (S) ____ Valleys (V) ____ Mountains (M) Chapter 19: Investigation Worksheet; page 2 Table 3. Short Report In the space below, write a short report summarizing the geology of the planet and its geologic history. Your instructor will guide you about the length and detail expected. This report should demonstrate the breadth of knowledge you have gained in this course, not just the concepts from this last chapter. Name _______________________________ Chapter 19: Investigation Worksheet; page 3 Table 4. Simple Geologic Map (optional) If instructed to by your instructor, draw detailed boundaries between regions and show the location of various geologic features, such as craters (outline with a dashed line), volcanoes (show with a triangle [▲]), and possible faults (show with a dark line). Include a legend next to the figure. Legend
