Which term describes a model used to explain natural-world phenomena?

• A. Hypothesis
• B. Atom
• C. Scientific model
• D. Isotope

Answer: (C)

Models help scientists explain natural-world phenomena by providing a simplified, workable representation of how things work. A scientific model can be physical, like a diagram or device; mathematical, using equations and simulations; or conceptual, a framework that organizes ideas. It’s used to explain observations, reveal relationships, and make predictions that can be tested and refined as new data come in. For example, a model of the atom or a climate model helps us understand complex systems by focusing on key factors and interactions, even though it may not capture every detail perfectly. A hypothesis, on the other hand, is a testable statement about what we expect to observe, not a representation used to explain phenomena. An atom is a basic unit of matter, and an isotope is a version of an element with a different number of neutrons. These are specific concepts, whereas a scientific model provides the framework we use to explain and explore natural phenomena.
