I think that is wrong because for science, they always switch the answers around. So please put your answers in words. I'm just here to check my work by the way. Thank you!

To answer the questions about natural hazards for the Connections Academy test, it's important to understand the concepts and principles behind each question. Here's a breakdown of each question and guidance on how to find the answers:
1. Which option correctly describes how scientists use seismic waves to locate an earthquake epicenter?
To answer this question, you can research or recall the process scientists use to locate an earthquake epicenter using seismic waves. Look for information about how the arrival times of P-waves and S-waves at different seismograph stations help determine the earthquake's epicenter.
2. Which strategy could an engineer use to design an earthquake-safe structure?
For this question, think about the various techniques engineers can implement when designing earthquake-safe structures. Research or think about techniques like base isolation, damping systems, or flexible structures that can help a building withstand the forces generated by an earthquake.
3. Why do scientists place GPS receivers near a volcano?
To find the answer to this question, consider the purpose of placing GPS receivers near a volcano. Research or think about how GPS receivers can track ground deformation caused by volcanic activity. This information helps scientists monitor and predict volcanic eruptions.
4. Ground vibrations are one type of volcanic activity that allows scientists to predict eruptions. Which two other types of volcanic activity do scientists look for?
This question requires you to identify two other types of volcanic activity that scientists monitor to predict eruptions. Research or recall information about volcanic gases, ground deformation, or changes in the volcano's shape or behavior as indications of an upcoming eruption.
5. Scientists use data to predict that a Category 5 hurricane will move out to sea, causing minimal damage to the coast. Which of the following likely provided the data?
To answer this question, consider the various sources that provide data for hurricane predictions. Look for information about weather models, satellite imagery, or data from weather monitoring systems (such as buoys) that can help scientists analyze and predict the hurricane's path.
6. Radar shows that a hurricane has sustained wind speeds of 170 miles per hour with heavy precipitation. Which is the best prediction of hurricane damage to trees in the hurricane’s path?
Think about the effects of strong winds and heavy precipitation on trees during a hurricane. Research or consider how the combination of high wind speeds and heavy rains can lead to uprooting, breaking branches, or defoliation, which will help you make the correct prediction.
7. How do hurricane straps make a building more stable?
To answer this question, research or think about the purpose and function of hurricane straps. Look for information on how hurricane straps (also known as hurricane ties) secure the roof of a building to its walls, making it more resistant to uplifting forces during strong winds and storms.
8. Which is the greatest advantage of using controlled burns versus allowing wildfires to occur naturally?
Think about the benefits and drawbacks of controlled burns compared to natural wildfires. Research or think about how controlled burns can reduce excess vegetation, mitigate the risk of larger, uncontrolled fires, and promote ecosystem health by maintaining natural fire regimes.
9. Which information is used to regularly update the Fire Potential Index (FPI)?
To find the answer, research or recall what factors contribute to determining the Fire Potential Index. Consider elements like weather conditions (humidity, temperature, wind), fuel moisture, fuel type and density, and fire history, which are typically used to assess fire danger and update the FPI.
10. Which might be one reason why firefighters would allow a wildfire to continue burning, instead of putting it out?
Consider the factors that firefighters take into account when deciding to allow a wildfire to continue burning. Research or think about factors like the wildfire's location, intensity, threat to populated areas, available resources, and the potential benefits of a controlled burn for ecological restoration or suppressing future wildfires.
11-12. These questions ask you to describe one way to retrofit a structure to prevent it from collapsing during a Category 5 hurricane. Think about techniques or modifications that can help reinforce structures against high winds, heavy rain, and potential storm surge. Research or consider options like adding hurricane straps/ties, reinforcing weak points (such as windows, doors, and garage doors), strengthening roof connections, or installing impact-resistant windows or shutters.
Remember to review your answers for accuracy and clarity before submitting them for the test. Good luck!
