what do you think keeps the GRS spinning over such a long period of time? (Hint: Don't just look at the spots.) Question 7 options: The rotation of the GRS is stabilized by the zone and belt that it sits in between. The zone and the belt have opposite directions of motion which re-enforce the direction of rotation of the GRS. The rotation of the GRS is stabilized by the zone and belt that it sits in between. The zone and the belt have same directions of motion which re-enforce the direction of rotation of the GRS. Since the GRS sits completely in a zone, it is stabalized by the motion of that zone. Since the GRS sits completely in a belt, it is stabalized by the motion of that belt
