Part 2 due Sunday 10/29 11:59 pm
Administrative Items for your map and/or profile: • Remove Grid (Google Earth Menu: “View/Grid”): this is too many lines to have turned on when making
your map screenshots • Your specific PL:
o Feel free to change the color of your line o Turn off other student’s lines
• De-select unnecessary items from “Places” o For example, circles from our lab where we found the epicenter
• Orient GE North before making screenshots (see below for details) • Make sure you are viewing in vertical view (aka “Bird’s Eye View”) before making maps.
o Use the arrows top right of GE window to drive this. Tectonic Boundaries
• To help interpret what are the Tectonic Boundaries in your area, using the layer provided, you can click the “heading” (“Plate Boundaries”) for a legend (or “key”) to plate see boundary legend (colors):
Orient all Maps with “North UP”: Make sure your BM’s are oriented North before taking any screen shots:
• The “N” should be at “12 o’clock” or “due North.” • All maps involved in Earth Science are by standard oriented with North towards the top of the page. • You can “double-click” the “N” and GE will orient itself North:

Part 2 Details:
You will begin your Earth Science-based interpretation of your profile line (“PL”) and base map (“BM”). You will be building on the displays you have begun to make with your PL and your BM. In general you will be making observations about what you see on your line and being to evaluate them by making Mini-Sections:
1. List 5 Earth Science-Based Observations a. List at least 5 statements about your PL using your own observations of your BM and/or PL.
Either above sea-level or below sea-level. Use the additional layers provided for help. i. Examples include:
Convergence/subduction Major Earthquakes Divergence/Spreading Ridge Question what you don’t understand Lateral Movement/Transform Fault How did the low areas develop Mountain Building What is the current topography? Volcanoes What does the flow of major rivers tell you? Textural Features on Seafloor Is the ocean basin getting larger or smaller? Major/Abrupt Changes in Elevation What will the area look like in 1 Million Years?
b. Bullet Point out evidence you see visually for the above observations. Be as specific as possible. a. Describe what processes are going on or have occurred which result(ed) in what
you see. Try to use Earth Science “vocabulary.” b. Evaluate the topography c. Discussion regional strike and dip
i. What direction(s) are the mountains/major tectonic features striking ii. What direction is the subduction zone striking
iii. What is the dip of the subduction zone
2. Identify 3 “Areas of Interest,” to be referred to as “AOI’s along your profile line. a. Describe what you see attempting to use Earth Science “vocabulary” b. Evaluate the topography. c. Discussion regional strike and dip
3. Make Mini-Sections of your 3 “Areas of Interest.” (See Below for detail).
a. These mini-sections will give you great resolution or detail about the feature you are evaluating b. Use this detail to refine your observations you detail c. You need to carry through your labelling of these mini-sections by including the width of each
line and the geographic orientation of each line. (like you did in your assigned PL.)
4. Make 3 Transverse-Sections, one through each of your 3 “Areas of Interest.” (See Below for detail). a. These mini-sections will give you great resolution or detail about the feature you are evaluating b. Use this detail to refine your observations you detail c. You need to carry through your labelling of these mini-sections by including the width of each
line and the geographic orientation of each line. (like you did in your assigned PL.)
5. Make Map or Maps to document each of your Mini-Sections and Transverse-Sections a. These Maps should be annotated labelling your lines. b. You can number them or letter them, whichever you choose. c. Carry forward your other labels (plate names, arrows of movement, etc)
One high point hits at Medelin, which is a city in Columbia. It is named the “City of Eternal Spring” and has a population of 2.5 million and area of 147.5 mi2.
Not an ES-Based

“Mini-Sections “of your PL: In the below image I illustrate how making shorter PL’s along your elevation profile can accentuate/highlight/provide more detail of the features in that portion of your PL. We will call these Mini- Sections.
• You will make smaller lines to investigate your AOI’s • You will use these smaller lines to make additional profile lines highlighting details of your AOI’s for your
presentation • Focus on features that interest you
This section highlighted in blue is the same as the section in Image 2 highlighted in blue.
This section highlighted in green is the same as the section in Image 2 highlighted in green.

“Transverse-Sections “of your PL: Exactly like the Mini-sections, making shorter PL’s PERPENDICULAR (or at a high angle to/transvers to) your assigned PL can accentuate/highlight/provide more detail of the features in that portion of your PL. We will call these “Transverse-Sections.”
• You will make smaller lines to investigate your AOI’s. • The line oriented N-S, boxed in dashed orange is an example. • You will use these smaller lines to make additional profile lines highlighting details of your AOI’s for your
presentation.
