Condensation- when air temperature cools down to the dew point and the water vapor
turns into liquid.
Deposition- when air temperature cools down to the dew point and the dew point is below
freezing and water vapor turns into solid.
Condensation Nuclei- solid particles in the atmosphere that provide surfaces on which
water vapor condense. Ex; ice, dust, smoke, salt, sand.
Haze- formed by small particles, usually pollution, serving as condensation nuclei.
