Answer to Question 1

Answer: The ground and objects on the ground are net radiators of terrestrial radiation at night (when solar input is absent), so are often cooler than the surrounding air. As air comes into contact with these cold surfaces, it cools. As the air cools below its dew point, water vapor condenses onto the nearest available surface, the ground or a twig or blade of grass.
