Many days I walk out to my car to go to work and notice my windows are fogged up, I believe due to dew (haha homophones). When I am at my mother's house(O'Fallon, MO), all Windows get fogged up. When I am at my father's house (Saint Charles, MO), only one side of the car is fogged up.
This is kind of a two-part question. 1) How does dew accumulate? 2) Why would it only accumulate on one side of my car?
I suspect it has to do with the fact the side that does not fog up faces a tree. This is very curious to me. Since I am not sure what else is needed to answer my question, I will update as comments come in.
