Question

describe how the gravitational theory explains earthquake

Answer 1

The gravitational forces responsible for high tides may also play a role in triggering major earthquakes, a study suggests. A Japanese research team found that large earthquakes are more likely to occur at times of a full or new Moon.

Answer 2

Answer:

Earthquakes occur because pressure builds up as sections of the Earth's crust move relative to one another. ... These sections, known as continental plates, meet at “fault lines” and the resulting movement of mass can lead to changes in the local gravity
