Actually, rainbows are a full circle -- not an arch. Since the atmospheric conditions that allow you to see them are only really present when the sun is low on the horizon (either early in the morning or late in the afternoon), the sun's angle to the ground is small, so half the full circle is blocked by the ground. But it's always a full circle -- because the light source that causes them, the sun, is round -- even though you usually only see half of it.
It has NOTHING whatsoever to do with the shape of the earth -- only with the shape of the light source (the sun). Go out on a full-moon night when there's lots of moisture or ice crystals in the air -- you'll see a "ring" around the moon that takes up half the sky or so...same thing that causes rainbows, but here you can see the full circle.
I've seen a full rainbow -- the whole circle -- a few times, while in an airplane at 30,000 feet or so :) It's very beautiful!

So that the leprichons can keep there gold safe. And so the Unichorns the fly have a path to there home. School said it was curving of earth surface, hah! the world is flat, everyone knows that.

th main reson for this is that it reflects the earth shape, which is spherical. as when sun light hits the earth, with water drops in the center. it gets reflected and shape of the earth is shadowed

Because they follow the curvature of the earth.
