Moon is beyond earth's gravity region(that might be the reason why it's not cllapse with earth) .If it's beyond earth's gravitational force why it's rotaing earth?

The moon is not beyond the earth's gravity. It is the balance between the velocity of the moon and the gravitational pull of the earth at the distance of the moon that keeps the moon in an orbital path.
By rotating earth, I assumed you meant revolving about the earth. Incidentally, the moon actually revolves around the sun in a path that is strongly affected (perturbed) by the earth. It's path relative to the sun is a wavy pattern, inside and outside the path of the earth, that is always concave toward the sun. However, the distinction between it revolving about the earth or the sun is very slight, and the difference isn't enough to affect the physics of getting to the moon or describing it's path.

The moon is not beyond the earth's gravity; the earth is not beyond the moon's gravity, they orbit each other as a result of their mutual gravitational attraction.
