Question
use the polar map given (Figure 2.8) to plot the changing locations of c pole over time. To view the polar map, imagine that you are above the and the lines of latitude, measured in 2 degree increments, from the sn Fole looking down on it. 90° N latitude is directly in the center of the map, spread out in circles center. Values of longitude are also given, and are represented as lines that radiate out from the center in increments of 30 degrees. A scale bar, in kilome- ters, is provided. To familiarize yourself with the map, first practice plotting some of the locations given. The first two, A and B, have been done for you. You will be plotting actual locations of the magnetic North Pole over time ranging from 1400- 1900 AD onto Figure 2.8. The table below includes the year and latitude and longi- tude (as degrees from o to 360) for each location. Once you have completed this, answer the questions that follow. Remember that 1,00o meters 1 kilometer. Point Year Latitude Longitude 87.7 85.6 C 140084.8 D 1500 | 86.3 E 1600 85.6 F 1700 81.1 G 1800 81.1 160.3 6,6 228.3 301.5 316.7 307.1 297.1 H 1900 82.3 288.2 10. Measure the distance, using the bar scale, between the pole in 1400 and 1500 (locations C and D). How far did the pole move? a. -50 km c. -600 km b.-150 km d.-1,000 km Figure 2.8 | Add the magnetic pole locations to this polar map and answer the questions below. 11. How far (in km) did the pole Authors NASA move in one year during this Source: NASA time period? License: Public Domain c. 6 km d. 10 km a. 0.5 km b. 1.5 km ,12. How far did the pole move in meters in one year during this time period? b. 500 m c. 10,000 m d. 6,000 m a. 1,500 m Page l 30Explanation / Answer
1. using Scale given answer seems to be -1000kms option: D.
2. if in 100 yrs it moved 1000 then in one year it moved 10km option: D.
3. one year 10 km means 10000 meters
