World NGS Physical / Ocean Floor Wall Map PAPER

Superb representation of the ocean floor in this paper version, 110x76cm/ (43" x 30" approx.) physical map of the world, one of the most interesting titles in the National Geographic Society’s long list of wall maps. Drawn with great skill to achieve a 3-D effect, ocean floor plains, basins, continental shelves, trenches, ridges and fractures are shown with their names, indicating in many places their depth in metres. On land masses relief shading shows the mountain chains, whilst the colouring indicates different types of terrain: arid regions, vegetation, tundra, etc. The map has names of mountain ranges, plateaux, deserts, plains, etc., but no country names or boundaries, with only selected major cities marked. The two Polar Regions are presented as insets in the top corners, while at the bottom two colourful maps of the world show the tectonic plates with the earth crust coloured according to its age, plus the world’s climatic zones. Projection is Winkel Tripel, which reduces distortion of land masses as they near the poles. * This title is also available encapsulated, plus in a bigger size (175.5 x 121.5cm / 5ft 9” x 4ft approx.) on paper or encapsulated.
