Question

though its impossible to accurately predict most natural disasters, scientists use different tools to monitor the chances of their happening. landslides are an issue in many parts of the world. researchers in italy are trying to improve landslide monitoring using optical fiber sensors. the sensors are embedded in mountain slopes to keep track of movement. volcanoes such as mount etna in italy and mount st. helens in the united states are a constant threat. both have been active in recent years. to help people prepare for an eruption, experts can monitor active volcanoes with satellite cameras. these cameras are used to detect increasing temperatures around volcanoes. earthquakes are also a concern in many areas. to aid earthquake - monitoring efforts, researchers use laser beams, which can detect plate movements in the earths crust.
match the problems with their solutions.
problem
earthquakes are difficult to predict.
landslides are difficult to predict.
volcanoes are difficult to predict.
solution
researchers use optical fiber sensors to monitor them.
researchers use satellite cameras to monitor them.
researchers use laser beams to monitor them.

Explanation:

Match each natural disaster monitoring problem to its corresponding solution based on the provided text.

1. For landslides, the text states Italian researchers use optical fiber sensors for monitoring.
2. For volcanoes, the text notes experts use satellite cameras to monitor active ones.
3. For earthquakes, the text says researchers use laser beams to detect crust plate movements.

Answer:

1. Landslides are difficult to predict. → Researchers use optical fiber sensors to monitor them.
2. Volcanoes are difficult to predict. → Researchers use satellite cameras to monitor them.
3. Earthquakes are difficult to predict. → Researchers use laser beams to monitor them.
