North and South: Opposite Seasons
NASA now makes images of the whole Earth every month. There are no clouds
in the images. They combine many pictures taken at different times. The
polar ice caps look bigger than they really are.
The movie begins in January. It is winter in the North and summer in the
South. Over time, you can see the ice and snow melt in the North. Then it
returns for the next winter.
There is not as much land far in the South. The change in the snow is less
clear. You can see the land in the South grow more green in the
summer. Then it grows more brown in the winter.
You can see it with your own eyes! The seasons are opposite in the North
