Why are dewdrops not formed on a cloudy night?

Consider the following statements about the natural vegetation of the world:

1. In the equatorial rainforests the crowns of the trees form a dense cover, so little sunlight reaches the ground and the forest floor carries thin undergrowth.
2. Many plants of the Mediterranean region have thick bark and small waxy leaves, which help them get through a long dry summer.
3. Trees of the temperate deciduous forests shed their leaves before winter, which cuts their water loss at a time when soil water is frozen.
4. Trees of the equatorial rainforest do not all shed their leaves at the same time, so the forest looks green through the whole year.

How many of the statements given above are correct?

3. Hot springs and geysers are found mainly in areas of present or recent volcanic activity, where groundwater is heated by hot rock below.
