What causes moonquakes?
==> a) The stretching of the moon from the Earth's tidal forces.
b) The joining of two moving plates on the Moon's crust.
c) Convection in the Moon's asthenosphere.
d) None of the above
----------------------------------
There are at least four different kinds of moonquakes: (1) deep moonquakes about 700 km below the surface, probably caused by tides; (2) vibrations from the impact of meteorites; (3) thermal quakes caused by the expansion of the frigid crust when first illuminated by the morning sun after two weeks of deep-freeze lunar night; and (4) shallow moonquakes only 20 or 30 kilometers below the surface.
