Nefesh HaChayim, Reb Itzele's Long Annotation

And some of them are the effects of the waters, both moist and cold, as in the context of “and with the bounty of the moon’s yield”. And some of them are the effects of the wind, as in the context of “that it multiplies via the air”441Eiruvin— “wind after a rainfall is as rainfall itself, and sun after rain is like two rainfalls”442Taanit 3b. As is known, it’s the nature of fire and the wind to fly upwards, and water descends to low places, to the dust. And if the elements of wind and fire attach to the element of water, they too contribute their influence and are drawn to the earth. Then via the element of dust all of the varieties of vegetation are revealed when all three elements combine appropriately.
