Question

Attached is a map of the ocean floor. It shows plate boundaries and features of the continental margin. All that you have to do is drag the letters from below and place them where they belong. You can open the attached tutorial to learn how to add letters and symbols. 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 (USGS Earthquake Site), label the quakes over a 5.0 magnitude () and the quake closest to your location ().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.
