Answer:
The heights of the tides change over the course of a month due to -
the position of Sun , Moon and Earth .
Step-by-step explanation:
Tides are formed due to the gravitational attraction of the sun and the moon on the surface of the Earth .
Since , the Moon is closer to Earth as compared to the Sun , Hence , Moon has greater attraction on Earth than Sun .
Moon plays an important role for producing the Tides .
In every 27.3 days , the Earth and the Moon revolves around the common point .
Therefore , in every 27.3 days , a new tidal cycle forms .
Two types of tides are possible , high tide and low tides .
In a day , two high tide and two low tide occurs ,
And because of the angle of Moon with respect to Earth , the two high tides do not have the same height . same for the case of two low tide .
The height of tides differ in the height on a daily basis .
