blue
white
yellow
red
18
Most of the mass of the solar system is:
Jupiter

The windward sides of mountain ranges are usually wet and cool because:
windy air usually contains more moisture than still air
as air sinks, it gets warmer
rising air cools and water condenses during precipitation
the mountain acts as a barrier to the wind
20
