The phrases that describe what the rock cycle shows are:
- how rocks change from one type to another
- which processes are involved in rock changes
- what makes some rocks change more slowly than others
The other phrases, "that the changes follow a specific order" and "that the process of change is very rapid," do not accurately reflect the rock cycle. The rock cycle is not linear and can vary in time, hence it doesn't follow a strict order and changes can occur over varying periods—from very slow to more rapid processes depending on the conditions.
