Some geologists hypothesize that the tug and pull of lunar tidal forces are strong enough to trigger volcanic eruptions and earthquakes. Explain how you think this might happen. How would you test your hypotheses and what data would you need?
What will be an ideal response?
The gravitational pull of the lunar tides is a force that stresses Earth. This force might help to draw magma closer to the surface to cause an eruption. The force might also add to the accumulated strain along a fault and provide just enough additional deformation to trigger an earthquake. To test these hypotheses, I would need to compare the times of volcanic eruptions and earthquakes to the times of the high tides at each location and see if eruptions and earthquakes are more common at these times than on other occasions.
