tides
tides The rise and fall of the Earth's oceans, caused by the gravitational attractions of the Moon and Sun. At the Earth's centre, centrifugal force due to the motion of the Earth about the barycentre of the Earth–Moon system is balanced by gravitational force. On the side of the Earth nearest the Moon, the Moon's gravitational pull is greater than centrifugal force, while on the opposite side the centrifugal force is greater. In both cases a tidal bulge is produced in the oceans. The Sun's tide-raising power is about one-third that of the Moon, as a result of its greater distance from the Earth. The Sun and Moon act together at new or full Moon to produce extra-high and extra-low tides; these are the so-called
spring tides. When the Moon is at first or third quarter the Sun and Moon are acting in different directions. The high tides are then at their lowest and the low tides are at their highest; these are the so-called
neap tides. The Moon and Sun also raise measurable tides in the solid Earth and its atmosphere. The Earth raises tides in the Moon, its force being a maximum when the Moon is at perigee.
