The Moon and the Bay of Fundy.

What causes a tide?
Gravitational forces of the moon and sun, and the spinning rotation of the earth, make tides rise and fall by tugging on the surface of the ocean. Eventually the surface mounds up and outward towards the moon. Along with daily movements of the moon, monthly lunar cycles are known to impact tides. While the moon pulls the water towards itself, it creates a lunar tide. This is a bulge on the surface of the ocean closest to the moon. As the moon rotates around the earth, the bulges shift, causing a change in the water levels.

Why do I care?
Chances are highly likely that you, the reader, live within driving distance of the Bay of Fundy. If you do not know where it is, here is a picture!

The Bay of Fundy is known to have the highest tides in the world. The average tidal range of oceans around the world is 3 ft. With the amount of water, the depth, and its unique shape causing resonance, these tides can range between 11-53 ft! The earth has a weak control over water because it is a liquid substance that is free to shift as it pleases. It is extraordinary how something that is 384,403 kilometers away can affect the world on a daily basis. That is why you care.
