Question description

Open the "GEO101L_Lab1_Map.docx" file provided. Expand the image (The bigger you can make the window, not the image itself, the easier it will be). All of the symbols/letters that you will need are below the image. If not, see the directions below.

How to complete the exercise:
Attached is a map of the ocean floor.  GEO101L_Lab1_Map.docx  It shows plate boundaries and features of the continental margin. All that you have to do is drag the letters from the bottom of the doc and place them where they belong on the map.

  • If you click on a letter/symbol, you will see a box form around it.
  • If you grab it by a line, not a circle, you can move it anywhere you wish.
  • If it is difficult to get the line, you can zoom in or make the box bigger using the circles.

Note: You will probably need more than one ★. If so, just copy ans paste it as many times as you need. 

When you are done, save the file to your hard drive for backup. You will now want to convert your page into a PDF. This will keep all of your labels in position.

  • On a Mac, you can just hit Shift+Command+S and change the format. Alternatively, choose Save as… and change the format.
  • On a PC, choose File in the menu, then Save As. Under Save as Type, choose PDF

Complete the following; you only have to label one of each feature except for the earthquakes: 

  1. Label each of the boundaries listed using the letters or shapes indicated: divergent (D), convergent (C) and transform fault boundaries (TF).
  2. Label each of the features listed: continental shelf, (SF) continental slope (SL), abyssal plain (AP), seamount (SM), trench (TR) and a hot spot (HS).
  3. Label Iceland (IL), Azores (AZ), Surtsey (SS). St. Helena (SH), Ascension (AS) and Tristan de Cunha (TC).
  4. Using the USGS earthquake site (, label the quakes over a 5.0 magnitude (★) and the quake closest to your location (Dallas, Texas).below. In the upper right hand corner of the page, you will see an icon that looks like a wheel or gear. Click on it and select 7-days, All Magnitudes, Worldwide. The three lines to the left of the gear provides you with a list of quakes starting with the most recent.
  5. Label the following: Rockies (RK), Himalayas (HM), Andes (AN) and Appalachians (AP).
  6. Label the following: Hawai’i (HI), Mt. St. Helens (ST), Etna (ET), Pelee (PE), Kilimanjaro (KI), Pinatubo (PI) and Fuji (FJ).

Questions:  Make sure that you answer each thoroughly.

  • Describe the relationship, if any, of the boundaries in #1 to the features that you labeled in #2.
  • Describe the relationship, if any, of the boundaries in #1 to the islands that you labeled in #3.
  • Describe the relationship, if any, of the boundaries in #1 to the quakes that you labeled in #4.
  • Describe the relationship, if any, of the boundaries in #1 to the mountain chains that you labeled in #5.
  • Describe the relationship, if any, of the boundaries in #1 to the volcanoes that you labeled in #5.
  • What do you think controls the appearance and form of the continental margin?
  • How do you think that the mountain chains in #5 formed?
  • Here is a thought question.  Reflect back on your answer to questions C and E.  Based on those responses, does it seem logical that Kilimanjaro is a much bigger volcano than any of the others, excluding Hawai’i?  Hawai’i is a different type of volcano.  Be sure to explain your answer.
