Relative humidity must be at least 100% before cloud droplets can form.

False

Explanation:

The relative humidity is the ratio of the water vapor to vapor pressure at a given temperature, the same amount of water vapor leads to the higher relative humidity in cooler air than in warm air i.e dew point. As clouds are composed of water droplets particularly ice crystals. As typical when the clouds are formed in a cool air the temperature equals the dew point. Which is 100% humidity resulting in condensation that produces clouds. Over the oceans, the ability to dissolve the salt and the ability to hold on molecules of water is called a Solute effect. This allows the clouds to form at a humidity of less than 100%. Nucleation is an initial part of a cloud droplet around any type of particle.

Evidence peice 1: millions of years ago existed the supercontinent pangea after millions of yearsnit broke into peices and formed smaller continents and islandsevidence peice 2: there is a massive fault line in san fransico and california that has the potential to cause massive earthquakes which supports the theory of fault linesevidence peice 3: mountains are said to be formed by earths tectonic plates crashing against each other for millions of years and eventually if forms a big point know as a mountain.evidence peice 4: the mariana trech is the deepest place (so far) discovered in the oceans of earth. it is so deep that you can literally see how earths plates are divided and or continents as well
