Pressure caused by the weight of the atmosphere. It decreases with increasing altitude.
The ratio of the amount of water in the air at a give temperature to the maximum amount it could hold at that temperature

damaging wave of light emitted by the sun - eads to cataracts in eyes, interferes with photosynthesis, kills phytoplankton, wakens the immune system
energy that travels in waves (includes solar energy, light energy)
