Activity 1: What Planet Earth looks like from Space
... From space planet Earth looks like a blue and white disc against a starry background. The colour comes from the world’s oceans which reflect the blue colour back into space. The white colour comes from the clouds. The clouds are just huge amounts of water vapour existing as very tiny droplets in the ...
