The theory of plate tectonics describes how the Earth’s lithosphere is broken into plates and these plates move over the molten magma below. Why is this considered a theory and not a law?

A. a theory is can not be proven and is based on opinion, a law is based on facts

B.A theory is developed by a single person or small group a law is developed by a large group of scientists

C. A theory can be modified as new evidence is uncovered, a law describes a relationship under certain conditions

D. A theory is developed by observing something under certain conditions and a law can be modified as new evidence is uncovered

Students were creating graphs to illustrate the energy transformations that occur as a roller coaster moves along a track. The letters A-D on Graph 1 represent the position of a roller coaster as it moves along a track. The numbers 1-4 on Graph 2 were supposed to represent the energy of the roller coaster at positions A-D, but the students got their data mixed up. How should the bars in Graph 2 be ordered so that they match to the energy of the roller coaster as it moves from position A to B to C to D?
