A team of scientists is evaluating possible methods for monitoring volcanoes.

Question

The scientists want to find the safest and most effective way to monitor volcanoes, so that they can spend money wisely.

Which method is the best choice for the scientists to invest in?
Scientists should choose the investigation method because this knowledge will help predict future eruptions.
Scientists should choose satellites and GPS technology because they allow remote observations once the sensors are deployed.
Scientists should choose portable seismographs because using them will allow for a detailed examination of the volcano during the survey.
Scientists should choose pH meters because using them will enable the creation of a detailed map highlighting soil areas that support plant growth.

Answer 1

In evaluating the options for monitoring volcanoes, scientists should consider both safety and effectiveness.

1. Investigation Methods: While these can offer insights into volcanic behavior, they may not provide real-time data or ensure safety in hazardous zones.

2. Satellites and GPS Technology: This method allows for remote monitoring, enabling the observation of volcanoes from a safe distance without the need to put scientists in harm's way. It also facilitates continuous data collection which is crucial in predicting eruptions.

3. Portable Seismographs: Although they allow for detailed examination, they may require closer proximity to the volcano, which could be dangerous during an eruption.

4. pH Meters: These are useful for assessing soil conditions but don’t provide comprehensive insights into volcanic activity or potential eruptions.

Given the importance of safety and comprehensive monitoring capabilities, satellites and GPS technology would be the best choice for the scientists to invest in. This method enables safe, continuous observation and can help effectively predict future eruptions, making it a wise investment for volcano monitoring.
