How are tides controlled?
Tides are controlled by the position of the sun and moon in comparison to Earth. This is why tidal range changes monthly. They're controlled due to gravitational attraction and the centrifugal effect

What are Spring Tides?
The tides are most distinct and have the largest ranges with high high tides and low low tides. Occurs when the sun, moon and earth are in a straight line so when there is a full or new moon

What are Neap Tides?
When the moon, earth and sun are arranged at 90 degrees and so the tides have a smaller range and are less distinct.

What is the Centrifugal Effect?
The effect where the ocean is pushed outwards causing low tide
