Which statement best describes how scientists are studying nature to predict a future event on Earth?
A They are observing nearby asteroids with an anemometer.
B They are measuring the temperature of ice sheets using a seismograph.
C They are observing the direction of ocean currents using an anemometer.
D They are monitoring for volcanic activity by using a seismograph.



I think it would be the letter D. As I have noticed, scientist uses that kind of instrument to predict the volcanic activity of a volcano. I am not sure if they could already predict the exact date of when a volcano would erupt but as far as I am concerned I know there's no such thing yet. Did I answer your question by this?
