NAME ____________________________________ 1. In the space provided, reconstruct the Rectangular Land Survey System demonstrating the location of the following: SW1/4, NE1/4, SE1/4, SECT. 27, T3NR4W, MDBM You should 1/ show the location of T3NR4W, MDBM, in one space; then in a separate space 2/ show the location of SECT. 27; then in a separate space 3/ show the location of SW1/4, NE1/4, SE1/4. (12 pts) 2. In the space provided, sketch your best interpretation of the profile (A?B, left to right) shown in the hypothetical topographic map. Make your sketch “to scale” to the extent possible. (12 pts) 400 ft 300 ft 200 ft 100 ft 0 ft 3. Regarding the profile in #2, above, a/ What is the highest elevation encountered along the profile?_______________ (2 pts) b/ What is the lowest elevation encountered along the profile? _______________ (2 pts) c/ What is the maximum relief along the profile? ___________________________ (2 pts) 4. Earth’s interior layers include lower mantle, inner core, asthenosphere, lithosphere, upper mantle, outer core . . . but in what order do they occur from where we live (a)—down to the very middle (f)? List them in depth order. (a) _________________________________________________________________ (2 pts) (b) _________________________________________________________________ (2 pts) (c) _________________________________________________________________ (2 pts) (d) _________________________________________________________________ (2 pts) (e) _________________________________________________________________ (2 pts) (f) _________________________________________________________________ (2 pts) 5. Regarding those interior layers of the Earth listed in #4, above: Which one is the most dense? ____________________________________________________________________ (2 pts) Which 2 interior layers of the Earth would encompass the greatest volume, or total area? ______________________________________ (2pts) and ______________________________________ (2 pts) 6. At the time of Pangaea, South America and Africa were attached forming a continuous landmass. Using the figure below, describe the tectonic process that has moved them to the positions they occupy today. _____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ (12 pts) 7. Regarding #6, above: What is this process called? (Fill-in the blanks below) ____________________ - _________________________ _____________________________________ (3 pts) 8. The Hawaiian Islands stretch across the Pacific Ocean in a NW-SE direction, with the oldest islands to the NW and the youngest islands to the SE. Explain how that came to be considering that only one permanent “hot spot” gave birth to them all. ______________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ (7 pts) 9. In the spaces below, sketch—USING YOUR BEST ARTISTIC ABILITIES!—the landform features/structures listed. Horst AND Graben (2 pts) Right Lateral Strike-Slip Fault (2 pts) Normal Fault (2 pts) Anticline AND Syncline (2 pts) 10. What type of stress caused each of those features identified above? a) Horst and Graben _____________________________________________ (2 pts) b) Strike-slip Fault _______________________________________________ (2 pts) c) Normal Fault _________________________________________________ (2 pts) d) Anticline and Syncline _________________________________________ (2 pts) 11. Fill-in the blanks: a) ____________________ eruptions are common with volcanoes that emit higher silica lavas, such as andesite. These volcanoes tend to develop into symmetrical, steep-sided mountains known as ____________________ volcanoes. Mount Fuji in Japan and Mount Rainier in Washington are good examples. These mountains develop steep sides by the buildup of alternating layers of ejected ____________________ materials, like ash and cinders. (6 pts) b) ____________________ eruptions of basaltic lava tend to produce wide, gently sloping mountains know as ___________________ volcanoes. The Hawaiian volcanoes are of this type. They can be very high, but they are not steep-sided. For example, Mauna Loa volcano in Hawaii is an exceptionally large shield volcano. (4 pts) 12. Assume that you had to walk 3.7 miles from the base of Mount Fujimorikaka at 127 feet above sea level to its peak at 14,298 feet above sea level: What would the “gradient” of that slope be? __________ feet/mile (4 pts)
