Answer:
A scientific hypothesis is a proposed idea based on the background research, therefore, the hypothesis is also called an educated guess. A hypothesis is prepared in such a way that can be tested through the experiments.
A scientific theory is a well-substantiated idea which explains the natural phenomenon in depth. The scientific theory is accepted only after the theory has been proved by many scientists.
Similarity and difference
The theory is the elaborate form of the theory as both hypothesis and theory explain the natural phenomenon and the difference is that a hypothesis explains the natural phenomenon to a limited extent but a hypothesis explains the natural phenomenon in depth.
