On the third day of creation God separated land and sea. He caused the dry land to appear. God also created vegetation on the third day.
With the formation of land the water could now begin the cycles of evaporation and condensation.
Think of all of the things associated with vegetation: roots, stems, leaves, grass, pollen, bark, vines, seaweed, fruits, vegetables, flowers, oxygen... Think of the smells and colours that existed by the end of the third day.
What else does the Bible have to say about plants and vegetation?
You cause the grass to grow for the livestock and plants for man to cultivate, that he may bring forth food from the earth
And God said, “Let the earth sprout vegetation, plants yielding seed, and fruit trees bearing fruit in which is their seed, each according to its kind, on the earth.” And it was so.
And God said, “Behold, I have given you every plant yielding seed that is on the face of all the earth, and every tree with seed in its fruit. You shall have them for food. And to every beast of the earth and to every bird of the heavens and to everything that creeps on the earth, everything that has the breath of life, I have given every green plant for food.” And it was so. And God saw everything that he had made, and behold, it was very good. And there was evening and there was morning, the sixth day.
