Predictable Vs Sudden Hazards Practice Test

Two hazards affected a hillside community.

Hazard A (wildfire): For 3 weeks, temperatures were high, humidity stayed low, and vegetation dried out. Fire danger alerts increased from “Moderate” to “Extreme.” A fire started after a lightning storm.

Hazard B (rockfall): A large rock broke loose from a cliff and fell onto a trail with no warning signs noticed by hikers.

Which hazard would generally allow more preparation time based on the buildup indicators described?

Two hazards were monitored near a mountain community.

Hazard A (volcano): Over 10 days, small earthquakes near the volcano increased from 2 per day to 30 per day, the ground slowly bulged upward, and gas measurements rose. Officials raised the alert level from “Normal” to “Watch.”

Hazard B (flash flood): A thunderstorm formed quickly, and a dry canyon went from low water to a fast-moving flood within 20 minutes.

Which statement about warning signs is supported by the evidence?
