Question
The craters on the Moon are all nearly circular. Why is this?
Most of the craters on the Moon were formed by volcanoes, and this results in circular craters.
It is believed that the objects that formed the impact craters on the Moon's surface all struck the Moon approximately perpendicular to its surface, and this would result in circular craters.
The objects that produced the impact craters came in at a variety of angles, but the craters were actually made by the shock waves generated by impact—and this results in circular craters.
The objects that produced the impact craters had been rounded by many previous collisions in space, and round objects produce circular craters regardless of their direction of impact.

Explanation / Answer
C) The objects that produced the impact craters came in at a variety of angles, but the craters were actually made by the shock waves generated by impact—and this results in circular craters.
Note: When the object hits the moon's surface ,the shockwaves disperse in all directions .The impact results in the formation of a crater . The impact disperses ejecta in all directions uniformly causing circular craters..The angle at which the impact object hits the moon does not effect the shape of the crater, but the craters were actually made by the shock waves generated by impact—and this results in circular craters.
