Have you ever wanted to actually see how Alaska experiences complete days in
darkness or daylight? Have you ever wondered why the International Dateline
has such significance in the business world? The National Geographic Planet
Earth can answer these questions and many more. With the light off the 10.5
diameter globe shows the political map of the world. When the light is on it
shows the physical features of the world - but that s not all.
This unique educational tool also shows day and nighttime for any time date
and location in the world throughout the four seasons. It can be manually adjusted
both forward and backward to see past present and future hours of daylight and
darkness for easy demonstration and understanding. A pinpoint light shows the
actual location of the sun throughout the year. Unique twilight rings depict
the three zones of dawn and dusk.
The superb design and engineering combined with the expert cartography of National
Geographic creates a learning tool that is fun and easy to use. Comes complete
with a detailed instruction booklet and Certificate of Authenticity.
