Final answer:
The statement that hurricanes and tornadoes are examples of personal situational factors is false. These events are environmental factors which have widespread effects on ecosystems and human populations, requiring preparedness and response solutions.
Step-by-step explanation:
Hurricanes and tornadoes that affect a large number of people are examples of personal situational factors is false. Hurricanes and tornadoes are natural disasters, which fall under environmental factors rather than personal situational factors. Personal situational factors are immediate circumstances or situations in an individual's life which may influence their behavior or condition, usually on a much smaller scale than environmental events like hurricanes.
When hurricanes, such as one hitting the Mississippi Gulf Coast, or tornadoes occur, they have the potential to cause widespread destruction, impacting ecosystems and human populations alike. Societies must, therefore, consider disaster preparedness, response capabilities, and the resilience of both social systems and infrastructures to such events. This involves engineering solutions, adaptation of social institutions, and considering population densities in vulnerable areas.
