Explain the difference between a hypothesis and a theory.

The hypothesis is the suggested explanation for a phenomenon while the theory is based on facts or tested explanation.

Explanation:

A hypothesis is a suggested explanation, an idea that is presented for argument so it can be tested to see if it is true. The hypothesis is made before any research has been done for it.
