Both the solid Earth and the water bulge due to the interaction between
the Moon and the Earth. The solid Earth tides are much smaller in amplitude
than those of the ocean water because they must overcome the elastic
rigidity of the Earth. The ocean tides are higher because the water can
flow laterally and thus respond to the changing gravitational forces.
