Global cloud cover, averaged over the month of October, 2009. The outlines of the continents can often be traced through observations of clouds alone, with the sharpest outlines where very dry land is surrounded by ocean. NASA composite satellite image; larger image available here.
Question 3: As a cloud matures, the dense water droplets may combine to produce larger droplets, which may combine to form droplets large enough to fall as ________.
Stratocumulus clouds, between Cumulus in the foreground and background

Question 6: Cloud droplets tend to ________ light efficiently, so that the intensity of the solar radiation decreases with depth into the gases, hence the gray or even sometimes dark appearance at the cloud base.
Question 7: On Earth the condensing substance is typically ________, which forms small droplets or ice crystals, typically 0.01 mm (0.00039 in) in diameter.
