For many days, Maya's city stays over 100°F, even at night. People can get heat exhaustion or heat stroke, especially kids and older adults. Based on the description, what weather hazard is described?
- Flood
- Tornado
- Blizzard
- Heat wave (correct answer)
Explanation: This question assesses the 3rd grade ability to identify weather-related hazards, which is a prerequisite for NGSS 3-ESS3-1: making a claim about the merit of a design solution that reduces the impacts of a weather-related hazard. Weather hazards are dangerous weather conditions that can damage property and threaten people's lives—they include tornadoes (violently rotating winds 100-300+ mph extending from thunderstorm to ground), hurricanes (massive rotating storms from ocean with 74+ mph winds and storm surge flooding), floods (water overflow onto normally dry land from heavy rain or rivers overflowing), blizzards (heavy snow + strong winds + low visibility + extreme cold), droughts (extended period without rain causing water shortages and crop failures), and heat waves (prolonged extreme heat causing heat stroke risk). Heat waves have sustained high temperatures (90-110°F) for days/weeks, causing heat-related illnesses especially for elderly and children. The hazard described in this scenario includes many days over 100°F, even at night, leading to heat exhaustion or stroke, especially for kids and older adults, matching a heat wave. Choice A is correct because it accurately identifies the hazard as a heat wave based on the key characteristics described. Specifically, the prolonged extreme heat and risks like heat stroke match heat wave characteristics. Choice B is incorrect because it identifies a flood, which involves water overflow, not heat; a common error misreading conditions entirely. Teach vulnerability to groups like children and use decision trees for heat-based hazards.
