Final answer:
Scientific theories provide a structured explanation of natural phenomena, supported by facts and data, and encourage further scientific exploration.
Step-by-step explanation:
Scientific theories provide a framework for both current science knowledge and future scientific studies by providing a structured explanation of natural phenomena. Unlike subjective opinions, scientific theories are supported by facts and data which are collected through rigorous experimentation and observation. Additionally, scientific theories allow for the development of alternative hypotheses which can be tested and refined, encouraging further scientific exploration and discovery.
