Damage to homes in a bushfire is an example of what type of change?

Damage to homes in a bushfire represents an external, unplanned, and temporary change. This is because the damage occurs due to an outside force—the fire, which is a natural disaster. The "unplanned" aspect reflects the unpredictable nature of bushfires; they can occur suddenly without preparation or expectation. While the damage may initially seem temporary in that homes can be rebuilt or repaired, the timing and scale of recovery can vary significantly, so it's crucial to recognize that the impact does not produce a permanent transformation of the environment or structure in a conventional sense.

All these elements—being external, unplanned, and having a potential for recovery—accurately capture the nature of such damage resulting from bushfires.
