A ball rolling on the floor eventually comes to a stop. Which statement best describes this situation? A) The energy on the macroscopic scale and the energy on the molecular scale both decreased.

B) The energy on the macroscopic scale increased, and the energy on the molecular scale decreased.

C) The energy on the macroscopic scale decreased, and the energy on the molecular scale increased.

D) The energy on the macroscopic scale and the energy on the molecular scale both remained constant.

If you have the rest please put them down :)

Explanation:

C. The energy on the macroscopic scale decreased, and the energy on the molecular scale increased.

A. friction converts some energy on the macroscopic scale to energy on the molecular scale.

B. The mechanical energy of the system decreased because of friction.

B. The mechanical energy of the system at the beginning of the experiment is equal to the mechanical energy of the system at the end of the experiment.

B. the mechanical energy of the system decreased due to the transfer of energy on a macroscopic scale to energy on a molecular scale.

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
