Answer:
Explanation:
When I hear "transformation of energy from one form to another", I think of the system exchanging energy with its surroundings. A transformation of energy simply means the system contains a different type of energy than it previously did. One example I can give is a ball. A ball at the top of a hill has a maximum potential energy. If given the chance to roll, it will go to a minimum state of potential. This will convert all of the potential energy into pure kinetic energy, once it reaches the bottom of the hill of course.
the correct answer is physical erosion. hope it helps
