Tides:
Tides are caused by the gravitational attraction the ‘pull’ of the moon on the earth, sometimes assisted by and sometimes hindered by the Sun.At new and full moon, when the Sun, Moon and Earth are practically in a straight line the attractive force of the Sun increases that of the Moon. Such high tides are called spring tides.
