Waler shaping earths surface running alhining the portage, montana, topographic map use the portage, montana, 1. compare ha, topographic map (figure 6) and the stereogram (figure 7) to complete the following shown in the photo. 2. is the terrain in section 14, located on the west side of this map shown in the shetogram in figure 7 to the map in figure 6 then on the topographic map, outline the area relatively flat or hilly? explain. 3. label the areas that topographically resemble section 14 on the topographic map as'upland 4. describe the topography in the lower half of section 17, located three sections east of section 14. 5. section 17 contains a portion of the valley occupied by the missouri river. approximately what percentage of the area shown on the map is stream valley (similar to the lower half of section 17) and what percentage is upland? stream valley: - % upland: 6. which of the following best describes the shape of the missouri river valley along the line labeled d-d: wide valley with a floodplain or steep-sided v-shaped valley with no floodplain? the valley is a 7. calculate the gradient, or slope, of this portion of the missouri river by following the steps below: step 1: loca te a contour line that crosses the river. note: a guide contour crosses the river in section 26 (lower left portion of map). follow the guide contour to the right to establish its elevation. elevation: feet step 2: locate a second guide contour that crosses the river. note: look in section 11, between the letters vand e in the word river. what is its elevation? elevation: _feet a string and the bar scale to measure the approximate distance (to the nearest mile) between these two guide contours distance: miles step 4: calculate the gradient of the river using the following formula: gradient distance (miles) gradient: _feet per mile 8. approximately how many feet is the missouri river from ultimate base level (sea level)? height above ultimate base level: 9. what are the features in the river labeled with the letter a? (hint: see the inside front cover.) feet 10. based on your answer to question 9, are the missouri river and its tributaries actively eroding or depositing in this region? the missouri river and its tributaries are 11. over time, as tributaries erode and lengthen their courses in their headwaters, what will happen to the u areas? pland
