THESE ARE THE FACTS
Natural occurrences you should all be aware of...
Fire:
Will go out when water hits it
Will increase or decrease when air hits it
Will burn up plants and trees, nothing else really does anything
Water:
Will evaporate if it's too hot
Can make a hurricane with air
Can feed Earth's plants or dehydrate them
Air:
Can blow a fire out OR make it larger
Can also cut off the oxygen feeding the fire so that it dies
Can blow down Earth's creations, can't really harm it.
Earth:
Plants and trees will be burned by fire.
Rocks and other such things won't really be affected by fire unless it is at a very high temperature.
Trees can be blown over by air, but not boulders or mountains
Stronger Elements as opposed to weaker Elements:
I'm not going to give you a list of "you are stronger than fire if you are so and so". However I will ask you to remember the rules of mother nature. What tends to happen when water meets fire? Fire goes out. What happens when light meets dark? We usually end up with different shades of gray. Wind cannot blow over mountains, hurricanes cannot exist without water and wind. So please keep these in mind as the story progresses. Know your natural boundaries. But don't be afraid to push the limits either.
