Tides in Bermuda

You may be wondering how tides happen in our world? Before we answer that question we must know that there are four different tides every day. There are two high tides and two low tides every single day. This happens because of the gravitational pull of the moon. The moon is pulling the earth equal and opposite to the gravitational force. Different tides occur throughout the day since the moon rotates around our planet. Think of a tug of war between the moon and the earth. Tides occur because of the gravitational force of the moon. In the photo bellow it is interesting to notice that the seaweed is higher than the water line. The seaweed is so far up the beach because the high tide pushed it there. That means there is a low tide currently. A really high tide will occur during a full moon and a very low tide will occur during a new moon. To answer our initial questions tides are caused by the difference between the forces on each side of the earth.
