Which term describes evidence that does not involve direct observation?

• A. Direct evidence
• B. Indirect evidence
• C. Isotope
• D. Electron cloud model

Answer: (B)

Indirect evidence is evidence that doesn't come from directly observing the event or object. It relies on signs, traces, or effects to support a conclusion. For example, smoke can indicate a fire, or footprints can suggest someone was present, even if you didn’t see the act happen. In science, you might infer the existence of something unseen from measurable effects it has on other things, rather than observing it directly. Direct evidence would be something you observe firsthand, like witnessing the event or having a camera capture it. The other options describe things that are not about evidence you obtain from observation: an isotope is a variant of an element with a different number of neutrons, and the electron cloud model is a way of describing where electrons are likely to be.
