(i) The gravitational force of moon, the sun & the earth and the centrifugal force generated due to the rotation of the earth are two major factors responsible for the occurrence of tides.
(ii) When a place (meridian) faces the moon the gravitational force of the moon exceeds the centrifugal force of the earth leading to high tide here as the water is pulled towards the moon.
(iii) At the same time the place on the earth located at the opposite meridian to the place experiencing high tide, the centrifugal force of the earth exceeds the gravitational force of the moon. Thus, the water is pulled in the direction away from the moon leading to high tide.
(iv) The water required for the high tide moves in from places that are at right angles to those having high tides causing a low tide at those places.
(v) Thus, place located on the opposite meridian to the place experiencing high or low tide will also experience high or low tide respectively.
