What are the four ways that lightning can enter a structure?

The correct response identifies that lightning can enter a structure primarily by striking a metal object on top, a nearby tree, or overhead conductors. This is crucial because these points act as conduits for the electrical charge generated during a lightning strike. Lightning seeks the path of least resistance, which is often provided by conductive materials. Structures with metal roofing or antennas, for instance, can attract lightning strikes, allowing the powerful electrical discharge to flow into the building through these conduits.

Understanding this pathway emphasizes the importance of lightning protection systems and proper installation practices to minimize the chances of lightning entering residential or commercial buildings. By ensuring that any metal structures are connected to a grounding system, you can effectively redirect the electrical energy safely into the ground, which is crucial for the safety of those inside and the integrity of the building itself.

While the other options provided may reference legitimate concerns during a thunderstorm, they do not accurately represent the primary pathways for lightning strikes as described in the correct response.
