A student researching avalanches has taken the following notes:
• Avalanches occur when unstable snow layers collapse • They can reach speeds of 80 mph within five seconds • About 150 people die in avalanches worldwide each year • Backcountry skiing and snowmobiling are high-risk activities • Avalanche transceivers help locate buried victims
The student wants to emphasize the deadly speed of avalanches. Which choice most effectively uses relevant information from the notes?
Avalanches occur when unstable layers of snow collapse and slide down mountains.
Avalanche transceivers are essential devices that help rescuers locate victims buried under snow.
Avalanches can accelerate to 80 mph within just five seconds, giving victims almost no time to escape.
Backcountry skiing and snowmobiling are among the highest-risk activities for avalanche danger.
Correct Answer: C
Choice C. 80 mph in five seconds with no escape time shows deadly speed.
