Which dose a seismograph record?

Question

answers:

vibrations of an earthquake

flow speed of a volcano

wind of a hurricane

temperature of a wildfire

Answer 1

The correct answer is "vibrations of an earthquake." A seismograph is an instrument used to record and measure the seismic waves generated by an earthquake. It detects and records the ground motions caused by the earthquake vibrations.

Answer 2

Wind speed and storm surge are data collected to study which natural hazard?

earthquake

hurricane

wildfire

volcano

Answer 3

The correct answer is "hurricane." Wind speed and storm surge are data collected to study hurricanes, which are powerful tropical storms characterized by strong winds and heavy rainfall. Wind speed is a critical parameter to assess the intensity of a hurricane, while storm surge refers to the rise in sea level that occurs as a hurricane approaches land. Monitoring and studying these factors help in understanding the behavior, track, and potential impacts of hurricanes, thereby contributing to better preparedness and response strategies.

Answer 4

Which is a way to decrease lives lost in any natural hazard?

answers:

Personal radars

air quality testing

Early warnings

watering the forests

Answer 5

The correct answer is "Early warnings." Early warnings are a crucial way to decrease lives lost in any natural hazard. By having effective forecasting systems and alert mechanisms in place, people can be notified and take necessary precautions well in advance of a natural disaster. This allows for timely evacuation, preparation, and implementation of safety measures, ultimately saving lives and minimizing the impact of the event. Personal radars, air quality testing, and watering the forests can have their own benefits in certain contexts but are not directly related to decreasing lives lost in natural hazards as early warnings are.

Answer 6

The National Parks Service occasionally conducts controlled burns. How do these decrease the number of forest fires?

answers:

By destroying all trees so no forest fires are possible.

By removing small plants that provide fuel for fires

By getting rid of plants near buildings so they will not burn down.

By shutting down parks so people cant accidentally start fires.

Answer 7

The correct answer is "By removing small plants that provide fuel for fires." Controlled burns conducted by the National Parks Service are aimed at reducing the risk of more severe and uncontrolled wildfires. These controlled burns are carefully planned and executed under controlled conditions to remove accumulated vegetation, such as dry grasses, shrubs, and small trees. By removing this fuel source, the controlled burns help decrease the amount of available flammable material, making it more difficult for wildfires to spread and reducing the intensity of future fires. This proactive approach to managing vegetation helps maintain healthier ecosystems and reduce the risk of destructive wildfires. The other provided answers do not accurately describe the purpose or impact of controlled burns in relation to reducing forest fires.

Answer 8

What should ordinary people do to best reduce the impact and loss of lives from a volcano?

answers:

Keep their eyes and mouths uncovered

Learn to use scientific equipment

Follow advice of first responders

Buy special preventative equipment

Answer 9

The correct answer is "Follow advice of first responders." When dealing with a volcanic eruption, ordinary people should prioritize their safety by following the guidance and instructions provided by trained professionals, such as first responders, experts at local authorities, and emergency management agencies. These individuals have the expertise and knowledge necessary to assess the situation, monitor volcanic activity, and provide accurate information on evacuation procedures, sheltering, and other safety measures. It is important to stay informed, remain updated on the latest developments through official channels, and comply with any directives given by authorities to reduce the impact and potential loss of lives during a volcanic event. The other provided answers do not necessarily apply or relate directly to reducing the impact and loss of lives from a volcano.
