How the Tide and moon are related
by Nathan S Jackson R Preston S and Charlie O
What is a tide? How do they change throughout the day?
The tides rise and fall because of the gravitational pull between the Moon and Earth. Earth is tipped to one side as it rotates on its axis, the Moon revolves around the Earth, the gravitational pull between Earth and Moon gets stronger and weaker twice a day. The tidal patterns changes by 50 minutes every day. As the moon revolves around the earth it pulls earth closest ocean towards it.
How does physics tie into how the Moon causes tides?
High tides and low tides
Different types of tides
Spring Tides are formed when the Earth, Moon, and Sun are in a straight line causing the high tides to be very high and low tides to be very low. Spring Tides only occur when the moon is either full or new in its cycle.
Neap Tides are formed when the Moon is at the quarter phases of its cycle and forms a 90 degree angle with the sun and moon. Neap tides have a very low difference between the high and low tides because the swells cancel eachother out due to perpendicular gravitational forces of the moon and the sun.
Lastly there is a Proxigean Spring Tide which is a pretty rare and exceptionally high tide. It only occurs every 1.5 years and happens when the moon is unusually close to the earth at a point called the proxigee or when the moon is at the New Moon Phase when the moon is between the Sun and the Earth.
