See below.


Tides on Earth are caused by gravitational interactions with other bodies. The two bodies that have the most influence on the tides are the Sun and the Moon.

As the Earth rotates, different bodies of water will be in different locations with respect to the Sun and the Moon. The side facing the Moon will have the highest tide, while bodies of water not directly facing the Moon or Sun will have low tides.

The Moon is significantly closer to the Earth than the Sun, which makes up for its weaker gravity. The Moon has the most influence on tides.
