Sample Questions and Corresponding Answers
Below is a detailed collection of common questions found in a severe weather webquest, along with comprehensive answer explanations.
1. What is a tornado, and how does it form?
Answer:
A tornado is a rapidly rotating column of air that extends from a thunderstorm to the ground, creating a violent and destructive weather event. Tornado formation begins within supercell thunderstorms when wind shear causes the horizontal rotation of air. This horizontal rotation is then tilted vertically by the storm’s updraft, creating a rotating updraft known as a mesocyclone. If the rotation intensifies and extends toward the ground, a tornado may form. Tornadoes are characterized by their funnel-shaped cloud and are capable of causing significant damage due to their high wind speeds, which can exceed 300 miles per hour in the most severe cases.
2. Describe the main differences between a hurricane and a tornado.
Answer:
The primary differences between a hurricane and a tornado are related to size, formation, duration, and impact:
- Size:
- Hurricanes are large-scale storm systems spanning hundreds of miles.
- Tornadoes are much smaller, typically a few hundred yards wide.
- Formation:
- Hurricanes form over warm ocean waters through the organization of thunderstorms into a cyclonic system.
- Tornadoes form within thunderstorms, especially supercells, due to wind shear and atmospheric instability.
- Duration:
- Hurricanes can last for days or weeks, gradually weakening as they move over land or cooler waters.
- Tornadoes usually last from a few seconds to over an hour, with most lasting less than 10 minutes.
- Impact:
- Hurricanes cause widespread flooding, storm surges, and wind damage over large areas.
- Tornadoes cause localized but intense damage with their high winds and are often associated with severe thunderstorms.
3. What safety precautions should you take during a thunderstorm?
Answer:
During a thunderstorm, safety is paramount. The following precautions should be taken:
- Seek shelter indoors immediately, preferably in a sturdy building away from windows.
- Avoid using electrical appliances and plumbing, as lightning can cause power surges.
- Stay away from tall objects, open fields, and water bodies, which attract lightning.
- If caught outside with no shelter, crouch down in a low-lying area, avoiding tall objects, and do not lie flat.
- Monitor weather alerts via a weather radio or smartphone for updates.
- After the storm passes, wait until authorities declare it safe before going outside.
4. Explain what a blizzard is and the dangers associated with it.
Answer:
A blizzard is a severe snowstorm characterized by sustained winds of 35 miles per hour or more, along with falling or blowing snow that reduces visibility to less than a quarter mile for at least three hours. The dangers of a blizzard include:
- Extreme cold, which can lead to hypothermia and frostbite.
- Whiteout conditions, causing disorientation and increasing the risk of accidents.
- Snowdrifts blocking roads and pathways, making travel hazardous or impossible.
- Power outages due to heavy snow and wind damaging power lines.
- Isolation and difficulty accessing emergency services.
Preparedness involves staying indoors, stocking up on essentials, and avoiding travel during blizzards.

Key Concepts Explained in the Answer Key
1. Weather Phenomena and Their Causes
Understanding the science behind severe weather is vital. For example:
- Tornadoes are caused by severe thunderstorms with significant wind shear and atmospheric instability.
- Hurricanes originate from warm ocean waters, where heat and moisture fuel their development.
- Thunderstorms form when warm, moist air rises and cools, leading to cloud formation and potential severe weather.
- Blizzards result from low-pressure systems combined with cold air masses and strong winds.
2. Warning Signs and Monitoring
The answer key highlights how to recognize signs of impending severe weather:
- Dark, towering storm clouds
- Sudden changes in wind direction or speed
- Rumbling thunder or lightning
- Rapid temperature drops
- Increasing wind speeds and atmospheric pressure changes
Students are encouraged to stay informed through weather alerts and understand the importance of early warning systems.
3. Safety and Preparedness Tips
The answer key emphasizes the importance of:
- Having an emergency kit with food, water, flashlight, batteries, and a first-aid kit.
- Developing a family emergency plan, including designated safe places.
- Staying informed about weather updates.
- Knowing how to turn off utilities if necessary.
- Practicing safety drills regularly.
