Unit Three Resource

For tides, I found a helpful website. It was very helpful, but the most helpful part was the animated Gif that I found midway through the page.  It helps to show the the rotation of the moon and how that effects the tide. The link is posted below!

Tide Resource

Why do we have tides?

Tides occur as a result of the difference of force between the moon and the different sides of the earth.  We know this because of the Universal Gravitational Law, which states the larger the Distance, the smaller the force.  The smaller the distance, the greater the force.  

On side A of the Earth, labeled above, there is a small distance from the moon, and thus a large force.  Side B has a longer distance from the moon, making the force smaller.  Sides A & B experience different forces. 

From the moon to Side A, the net force is towards the moon, while on Side B, the net force is away from the moon.  

Boca Grande Tides

Tide Chart

The best chart on the page is midway through the website.

At 8:35, Boca Grande is in transition from High to Low tide.  The moon is just about a half-moon.  I know this because the cart has a convenient moon chart next to it.
