So for starters here are the elements:
Usually your element is the one you're most connected to. Some people have more than one element others are connected to all of the elements.
In my opinion, I believe that earth and air are more connected than all the others. Such as air and fire, they can't live without each other. Air gives the fire light and flame. Just like the water gives the Earth a healthy green color. Everything is connected together. There would be no life without the elements and there would be no "us".
