What is 3D?
How can it work?
What are the advantages and the disadvantages of 3D?
Israel, during the winter the North Pole is tipped away from the sun, so
that it does not receive any sunlight. Since there is no energy from the
sun on the polar area, energy is lost to space instead, thereby cooling
the polar area. The temperature stays fairly constant because of the ice
cover. The initial cooling is rapid, but slows to very little cooling
as time goes on in the winter.
