  2. I just turned this in and the answers are correct. I just wanted to pay you guys back for all the times you helped me out. Good luck on the written answers though idk how I did.

    1. The farther away, several seismographs
    2. Constructing
    3. to see
    4. Ground deformation, increase gas
    5. Satellite
    6. Most trees
    7. They secure
    8. Reduction of damaging
    9. Daily satellite data
    10. The fire
    11 & 12 answer in your own words.
    11. Retrofitting with straps was an answer up above. Talk more about that.
    12. Remember your lesson and use your own words but here are some ideas. Remove or prune flammable plants and shrubs near windows. Remove vegetation and items that could catch fire from around and under decks, balconies and stairs. Create a separation between trees, shrubs and items that could catch fire, such as patio furniture, wood piles, swing sets, etc.

  3. Which location has a high hazard level for seismic activity?
    - answer: California

    An earthquake occurs at a convergent boundary. The earthquake has a high magnitude, and an observer reports the earthquake having low intensity. Which statement about the earthquake is correct?

    - answer: The earthquake was caused by plates moving together. It released a lot of energy, but the observer did not see much damage.

    Which items include personal protective equipment (PPE) people would likely use to minimize the effects of a natural hazard?
    - answer: respirators and face shields

    Which statement best explains what people should do if a shelter-in-pace order is in effect as a result of a natural hazard?
    - answer: People should remain inside and close all doors and windows.

    Which structural damage could be expected if a Category 3 hurricane is predicted to hit an area?
    - answer: Well-built framed homes could incur major damage or removal of roof decking and gable ends.

    A scientist wants to study the movement of air in a hurricane in order to help prevent damage. Which tool should the scientist use to find out more about the movement of air?
    - answer: a Doppler radar

    Which is the best way to limit the damage caused by a hurricane?
    - answer: Provide as early a warning as possible to people living in the path of a hurricane.

    Use the scenario to answer the question.
    A scientist uses data from satellite images to draw conclusions about a region. After analyzing the data collected, the scientist issues a drought warning for the region.
    Which data best supports the scientist’s decision to issue the warning?
    - answer: Reservoirs and lake levels continue to drop significantly.

    The National Park Service sometimes creates controlled burns to mitigate wildfires. How does a controlled burn limit the spread of wildfires?
    - answer: A controlled burn removes dead vegetation that might otherwise help a wildfire start and spread.

    National Park rangers create public announcements to help prevent accidental wildfires from start. Which is a simple way that accidental wildfires can be prevented in these parks?
    - answer: Ensure people do not have unattended cooking fires while camping.

    11 ] In three to four sentences, explain how climate change could impact the formation of hurricanes.
    [ My teacher hasn't graded this yet so idk if this is good ]
    - my answer: If sea level temperatures rises, it could affect tropical storms and winds making them more dangerous l. Warm water can also affect hurricanes to be more intense and more dangerous. Warmer water also makes hurricanes form more frequently.

    12 ] In 3–5 sentences, explain how meteorologists use weather data to predict the probability of a catastrophic wildfire.
    [ My teacher hasn't graded this yet so idk if this is good ]
    - my answer: Scientists can use data to predict if there will be a potential fire/drought. If there is heat, dry weather, vegetation then there's a chance a fire will occur. If there is dry weather, dry land, low precipitation, then it is most likely a drought since scientists can gather information on different types on weather, temperature, and humidity.

    [ make sure to reword and change some stuff in 11 and 12 ]
