My world is flat. Water constantly pours over the edge, where it becomes vapor and forms clouds.
Assuming that magic is involved to create Earth-like gravity, what effects would this setup have on the wind conditions, air currents and water currents of this world? Assume no magic is involved to change the way these things work otherwise. If it is impossible to have any wind or currents, what possible changes could I make to the setup without adding magic to create them? Finally, is it possible for the human race to exist on such a world, and develop into a complex modern society?
The crust of this world is the size of the Earth's, and the depth of the ocean is roughly the same here as it is in real life. Global temperature is also roughly the same.
