Answer:
A hypothesis is based on an observation, while a theory is based on evidence.
Step-by-step explanation:
A hypothesis is a proposed explanation or prediction that is based on initial observations or experiences. It is a tentative assumption made to be tested and potentially validated or invalidated through further investigation.
On the other hand, a theory is a well-substantiated explanation of a natural phenomenon. It is supported by a vast body of evidence from multiple sources, such as empirical data, experiments, observations, and rigorous testing. Theories are built upon a foundation of scientific knowledge and are widely accepted as reliable explanations for a particular phenomenon or set of phenomena.
