PPT-Precipitation So far we’ve seen how air gets saturated with water vapor, causing some

crystals Is is simply a matter of the water droplets combining to form raindrops Answer No Cloud droplets are TINY It would take thousands of them happening to combine to form a single raindrop. A measure of the amount of water vapor in the atmosphere is called __________. Air can hold only so much water vapor. However, _______ air can hold more water vapor than _______ air. When a meteorologist (weather person) talks about this, they are usually talking about _______________________. This is the _____________ of water vapor that is actually in the air compared to how.
