How Does Low & High Tides Occur?
Here you are looking at the sun, the earth and the moon. The earth resolves around the sun and the moon resolves around the rotating earth. About 29% of the Earth is land and 71% is water. The blue part is water. The water level rises in the sea approximately every 6 hours and 13 minutes and after 6 hours and 13 minutes, this level decrease again.

Now to understand the tides, we have to apply both these forces here. First of all, Gravity has pulled the water from all the sides towards the earth. So, when the earth rotates round and round the centrifugal force work here and the water around it and does push towards. Also to maintain the volume of water pressure is applied on this entire water from top and bottom to the inside.
