Life on Smooth World
Welcome to Smooth World.
Most of this planet (at least two thirds, but preferably more) has only tiny differences in elevation, 30-40cm at most. No hills, no mountains, no valleys. Even plains found on Earth usually have a fair amount of difference in elevation, but not Smooth World. From a far enough distance the surface of this world seems to be mostly flat and smooth, hence its name.
The "smooth" surface of this planet is mostly covered in soil and a fairly even coverage of a grass like plant.
The remaining third (preferably less) of the world is comprised of whatever it takes to make this planet capable of supporting human life. I'm imagining this would be an ocean, but I am open to any ideas that makes this world capable of supporting life.
The world is approximately the same size as Earth, possibly the same kind of make up. I'm imagining that this world has no moon and is particularly old to facilitate the overall smoothness, but I am totally flexible on these points if they don't make any scientific sense.
How can I make Smooth World capable of supporting human life? I'm thinking of things like, a breathable atmosphere, protection from the radiation of space etc etc. We can assume that the humans living there have brought food, water and shelter with them.
The greater the "smooth" surface of this world, the better. If I have two good answers, but one of them has a greater percentage of smooth surface, that answer will get marked as correct. Ideally I'd want a world that was 100% smooth, but I don't think I'd be able to make it habitable if it was like this, but please correct me if I'm wrong here.
So, in addition to making this world scientifically feasible, I have two questions:
What will I need in this remaining "non-smooth" part to make this world habitable?
What will the weather be like on this world? More stormy or less stormy?
