I know (or at least I think I know) that pine trees use their needles to collect water. However, I do not know quite how they do this.
Do the needles/trees just wait for the fog to condense, or do they have a way to speed up/cause the fog to condense?
Also, does the fog even need to be condensed, because the fog wiki says fog “It is a visible mass consisting of cloud water droplets or ice crystals suspended in the air at or near the Earth’s surface.”
I am confused about the fact that fog “[consists] of cloud water droplets”. If the fog is made of water droplets, and not water vapor, then there is no need for condensation to collect water, since it is already tiny droplets? Unless cloud water droplets are different from water droplets? But if fog is made up of tiny water droplets, why don’t people get wet when walking through fog, like when walking through a drizzle? Perhaps it just happens on a smaller, much less noticeable level?
I guess, now that I think about it, droplets form everywhere when in fog, but I always thought this was from condensation, not from the fog being made of water particles.
Sorry, I know I have a lot of questions in here, but I didn’t think it was worth separate threads. To clarify what I’m asking:

Thank you very much.
