Final answer:
A theory explains a scientific phenomenon and is based on a body of facts that have been confirmed through observation and experiment, while a law describes a natural process and holds true universally.
Step-by-step explanation:
The difference between a law and a theory in scientific terminology is that a law refers to an observable phenomenon in nature that holds true universally without exception, while a theory is a well-substantiated explanation of some aspect of the natural world, based on a body of facts that have been repeatedly confirmed through observation and experiment. Therefore, the statement, 'A theory explains a scientific phenomenon whereas a law describes a natural process', accurately differentiates between the two.
