How do you view clouds?

When on Google Earth, why don't clouds obscure the view?

• Answer:

  Sattelites are all above the clouds, so if it's cloudy, that's all the photos will show (visible light of course, you can take pictures with radars or infrared that would show what's under the clouds, but those aren't the pictures Google is using). Sattelites circle the earth about every 90 minutes, so the steam of pictures is endless. Google just waits for pictures of a cloudless day in each area.
