Circular unless hit very hard
craters... :)
There are not only maps of the lunar craters, there are lunar globes that depict the Moon just as it is. Even better; there is Google Moon! www.google.com/moon

Most lunar craters are impact craters caused by incoming meteors and asteroids. Since our moon has no atmosphere there can be no glaciers or erosion.
Most lunar craters are circular. It takes a very unusual shallow (or grazing) impact to make a crater that is not circular.
All impact craters are circular, no matter what the shape of the impactor or the angle of impact. Of the options provided in the Discussion page, only choice "B" is accurate. The energy released in the impact melted the impactor - and the surface - to the point of being fluid, or at least malleable. Option "D", that the craters were formed early in the Moon's history, is probably also true, but the circular shape of the craters isn't dependent on this.
it is a result of an asteroid impact
Meteorite impacts.
They last forever.
noooooooooooooooooooo!
Craters are formed when asteroids and comets collide with the lunar surface.
There is water inside of craters or ice inside of craters
