Investigate Look at several maps in your atlas. Identify the type of projection used in each map. Investigate the AuthaGraph projection. Explain the advantages and disadvantages of this projection. Features of maps Maps contain features that help us to interpret them. (11) 9. World map with the Mercator projection 11. Physical map of the Arctic polar zone 10. World map with the Peters projection E X P L O R E Mercator and Peters projections The Mercator projection is a cylindrical projection created in the 16th centur y by Gerardus Mercator. It distorts the size of the regions as they move away from the Equator. (9) This is why Greenland , for example, looks bigger than in reality. In the 20th centur y, Arno Peters developed a cylindrical projection to correct the errors of the Mercator maps. Peters' projection preser ves the proportions between the Earth's regions, but distorts the shapes. (10) A. A title with information about the map. B. A key with the symbols and colours used on the map. C. A scale showing the proportion between the map and reality. D. The orientation. E. Various text labels with information. F. Lines of latitude (parallels) and longitude (meridians) to locate any point on Earth. 122152_01_p015_h1_mercator 122152_01_p015_h2_peters A las k a n R a nge Mountains Verkhoyanskiy U R A L M O U N TA I N S Hudson Bay Denali 6,193 m Narodnaya 1,894 m Yukon Beau fo rt Sea Lena Ob' Kara Sea LABRADOR PENINSULA Barents Sea Mackenzie Greenland Prime Meridian 10 º 0º 30 º 40 º 50 º 60 º 10 º 20 º 30 º 40 º 50 º 60 º 18 0º 17 0º 16 0º 15 0º 14 0º 12 0º 11 0º 10 0º 90 º 80 º 70 º 16 0º 15 0º 14 0º 13 0º 12 0º 11 0º 80 º 70 º 50 º 60 º 60 º 50 º 60 º Cí r cu l opo l ar ár tic o North Pole AR C T IC OC EA N 959069_01_p15_zona _polar_art ica 70º 17 0º 13 0º 10 0º 90 º 20 º 0 720 kilometres Sca le Major peaks Main rivers Lakes 2,500 m 2,000 m 1,500 m 1,000 m 400 m 200 m 0 m 959069_01_p15_leyenda_zona_polar_artica F E C D A B 15 1
