Quizplus · Accepted Answer

Rocks are formed through natural processes such as volcanic activity, erosion, and sedimentation. They are not created by humans, therefore they are considered natural. Coherent means sticking together and synthetic means man-made, so A and B are incorrect options. Rare does not accurately describe rocks as they can be found in many places on Earth.
