7 NYS Invitational Science Olympiad April 2005 Figure 14: Glacial Movement Base your answers to questions on the three maps below. The maps show the ice movement and changes at the ice front (terminus) of an alpine glacier from the years 1874 to Points A, B, C, D, and E represent the positions of large markers placed on the glacial ice and left there for the 8 year period. The position of the glacial ice front for 1874, 1878, and 1882 is indicated on each map. Figure 14: Retreating glacier. NYS Education Department (Earth Science Regents) 33. Explain what caused the glacial ice (as indicated by stakes A-E) to move as it did from Based on the position of the glacial ice front, is the glacier advancing, retreating, or remaining in the same place? 35.

17 Dynamic Planet - Glaciers Materials required: Name: Grinnell Glacier Series of twelve boundary maps of Grinnel Glacier Acetate graph with individual squares of 1/10 th kilometer each Thin line, water soluble marker of any color Paper towels one moist; the other dry Part I: Use the images and the grid you have been given to answer the following questions. 1. Is the Grinnell Glacier located on land or at sea? a. How do you know b. 2. How many individual squares are needed to blanket an area of one square kilometer? 3. What value represents the area within each individual square? Km 2 Part II: Determining the surface area of each glacier in square kilometers. Place the acetate onto the image and trace the outer boundaries of both parts of the glacier. (To avoid damaging the grid printed on the acetate, place the acetate so the title appears as a mirror image, i.e. you working on the reverse side of the acetate.) Place the acetate with the outline you have drawn onto a sheet of plain white paper for better viewing. Count and record the number of whole squares, within the boundaries of the glacier. You need only touch the center of each square with the tip of the marker leaving a small dot on each as you count. Make wholes out of partial squares, i.e. 2 halves equal one, 3 thirds equal one, etc. Add these totals to determine the area of the glacier for each year given and record these on the chart on page 2. These estimates, though not perfect, are accurate enough to make inferences about the size and wasting of the glacier.

Between which years did the Grinnell Glacier actually increase in size? b. What caused that increase in size? 6. What types of records might one consult to determine the relationship between glacial melting and global warming?

19 Grinnell Glacier Page 3 7. May the measurements of the Grinnell Glacier s area during the span of these observations be used to prove that global warming is currently occurring? Explain. 8. May the measurements of the Grinnell Glacier s area during the span of these observations be used to prove that man s activities are at least partially responsible for the shrinkage of earth s glaciers? Explain. 9. Between which years was the average yearly growth in area the greatest? 10. Between which years was the average yearly loss in area the greatest? 11. a. Where is Grinnel Glacier wasting at the fastest pace? b. Form a hypothesis as to why the glacier is wasting at that location rather than wasting evenly on its entire surface. 2004, Other Worlds Educational Enterprises

These were once lateral moraines which become medial moraines where two valley glaciers flow together. c. till; unsorted rocky materials eroded from the valley walls 3. a. ogives b. away (notice the curvature of the flowing ice lying perpendicular to the sides of the glacier) 4. hanging glacier (could be called an ice apron ) 5. terminus 6. ablation zone or zone of wastage 7. drift, outwash deposits 8. outwash plain or pro-glacial lake 9. cirque 10. a. horn 11. arête b. Horns are pyramidal peaks that form when several cirques chisel a mountain from three or more sides. 12. alpine or valley glacier 13. a. roche moutonnee b. The action of plucking on rock mounds when combined with glacial 14. a. erratic abrasion produces this feature. b. Glacial erratics are large rocks transported away from their source areas by 15. a. drumlin moving glacial ice sheets and deposited when the glacier melted. b. The narrow end of the drumlin points to the general direction of glacial advance; the steep end is the general direction that the glacier came from. 16. a. kettle lake b. When glaciers are retreating, numerous blocks of ice become detached from the main body of the glacier. If glacial drift is then surround the ice, a depression on the surface called a kettle hole can be created when the ice melts. Those reaching below the water table can form kettle lakes.

21 17. a. moraine or till b. till deposited along the edge of a glacier released when a glacier melts 18. cross-bedded drift; outwash deposit 19. a. Those in Figure 11 are well-sorted, fine, and deposited in well-defined layers or strata. b. Those in Figure 10 are poorly-sorted, large, with little obvious layering. 20. These sediments were deposited by meltwater streams in the outwash plain; 21. continental 22. Transantarctic Mountains 23. An ice sheet covers a very large area of land; an ice shelf is attached to an ice sheet but covers an area covered by water. 24. Valley glaciers are bound by valley walls and flow in the direction of the valley; an ice sheet is on a larger scale and flow in all directions; valley glaciers are thinner and smaller than ice sheets; 25. An ice sheet flows in all directions; a valley glacier flows in the direction of the valley. 26. Draw a straight line between 0 and 18 longitude and another between 90 W and 90 E latitude. The point where they cross is the South Pole meters 28. continental glaciers 29. outwash plain, kame, esker 30. drumlins, recessional moraine, terminal moraine, and gournd moraine 31. terminal moraine 32. A terminal moraine is a deposit that marks the farthest advance of a glacier. Moraine deposits created during halts in the retreat of the glacier are called recessional moraines. Moraines form when the glacier pauses for a period of time (accumulation = ablation). As it melts it deposits till, but the glacier acts like a conveyor belt bringing more sediments to add to the moraine. 33. The glacier flows more rapidly at its center than at its sides due to less friction between the hard rock and ice at its sides 34. retreating 35. less accumulation and greater ablation 36. global warming ± 5 meters/year 38. horn 39. a. arête

Description: a river at the center; gentle upslope from river on both sides; then much steeper walls. (U-shaped) 42. It decreased. In 1979 it was less than one-third the size it was in Much greater ablation than accumulation. 44. The climate is becoming considerable warmer. 45. The glacial ice is still flowing forward although it is melting as it approaches the glacier s terminus. 46. a. eccentricity shape of orbit b. obliquity tilt of Earth s axis (and a third: precession wobble of axis) 47. Minute pockets of ancient atmosphere became trapped within the glacial ice. These small amounts of atmospheric gases were carefully analyzed. 48. Pleistocene 49.

Glaciers will become smaller and smaller. b. Present coastal areas will become inundated with water. This exam was written by and submitted for publication on The Wright Center website by Gary Vorwald, P.J. Gelinas JHS, Setauket, NY. In 1993, a team of 6 teachers from New York and Washington State were chosen to participate in a three-week summer program to study of the Juneau Icefield Research Project. They spent three weeks at a remote field camp on an arête located between the Lemon and Ptarmigan glaciers. The "Glaciers and Climate" chapter included on the TASA Graphic s Earth s Dynamic Surface CD presents a comprehensive study of the 2006 topic of the Dynamic Planet event for use with both Divisions C and D. Participants are guided through each concept with full color animations, illustrations, and photographs while listening to the author's narration. A review section at the end of the chapter reinforces the concepts covered. Interactive activities encourage participation and problem solving.
