Question

Why might the emission of radon gas be useful in predicting earthquakes? group of answer choices fracturing of the rocks allows radon to move more readily. Cooled and solidified faults emit large amounts of radon. Radon gas indicates activity in the mantle, which drives plate tectonics. Radon gas causes seismic gaps

Answer 1

Answer: The answer is fracturing of the rocks allows radon to move more readily.

Step-by-step explanation:

As stress builds up in the Earth's crust prior to an earthquake, micro-fractures can form, allowing naturally occurring radon gas from underground to escape to the surface. Monitoring for elevated levels of radon gas might provide a clue that an earthquake is imminent.
