Earth as viewed from space in December 1990. South America is near the

center of the left-hand picture, while Africa is near the top of the right-hand

image. Antarctica is visible near the bottom of both images. Note how much

sunlight is reflected back into space by clouds and by snow and ice. Note also

how light the deserts of northern Africa appear as compared to the Amazon

forests of South America and the jungles of central Africa.
