NGS Physical/Ocean Floor World Map: ENCAPSULATED

£24.00

Superb representation of the ocean floor makes this encapsulated, 111 x 77.5cm (3ft 8” x 2ft 6” 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 in a larger size (175.5 x 121.5cm / 5ft 9” x 4ft approx.) on paper or encapsulated.

LAMINATED and ENCAPSULATED WALL MAPS:
- laminated wall maps have a thin layer of plastic usually applied to the printed side only. They can be written on with suitable marker pens without any damage to the map but, unless they have been laminated on both sides, they are not damp-proof.

- encapsulated wall maps are sealed between two sheets of plastic. They are more rigid and heavier than laminated maps of the same size. They are damp-proof and do not crinkle in humid conditions. Encapsulation gives the map a shiny surface, similar to being displayed behind glass.

- please note: many publishers and retailers often use these two terms interchangeably. Our map titles and descriptions follow the definitions provided above.
