About the Bending

Airbending is one of the four elemental bending arts, specifically, the aerokinetic ability to control and manipulate currents of air. The peaceful Air Nomads utilized this type of bending in their everyday lives.
Air is the element of freedom. The Air Nomads detached themselves from worldly problems and concerns; finding peace and freedom was the key to solve their flaws in life. Airbenders continually sought for spiritual enlightenment, and, as a result, all children born into the Air Nomads were benders. The first airbenders learned their art from the sky bison.
The key to airbending is flexibility and finding and following the path of least resistance. Airbending is notable for being almost entirely defensive, as well as the most dynamic of the four bending arts. Airbenders can overwhelm many opponents at once with large and powerful attacks that could prove fatal; however, due to the pacifist nature of the Air Nomads, such attacks are rarely used.

Earthbending, one of the four elemental bending arts, is the geokinetic ability to manipulate earth and rock, in all their various forms. It is utilized by people of the Earth Kingdom.
Earth is the element of substance, making earthbenders and their people diverse, strong, persistent, and enduring. The first earthbenders, Oma and Shu, learned the art from badgermoles.
The key to earthbending is utilizing neutral jing, which involves waiting and listening for the right moment to strike and, when that moment comes, acting decisively. In other words, earthbenders generally endure their enemies’ attacks until the right opportunity to counterattack reveals itself, then strike with unyielding force.
Metalbending and Sandbending are two types of earthbending. They are both very specialized and harder to learn.

Firebending, one of the four elemental bending arts, is the pyrokinetic ability to control fire and is unique among the bending arts, as it is the only one in which the user can create their element. Practiced by some people of the Fire Nation, as well as the lesser known Sun Warriors.
Fire is the element of power, consisting of overpowering force tempered by the unflinching will to accomplish tasks and desires. However, the recently militaristic Fire Nation twisted this into firebending being fueled by rage, hate, and anger. Firebending draws its power from the sun, and the first human firebenders derived their firebending techniques from the dragons.
Firebending is notable for its intensive attacking style and general lack of adequate defense moves, although some notable firebenders utilize creative defensive moves.

Waterbending, one of the four elemental bending arts, is the hydrokinetic ability to control water, as well as its many forms. This type of bending is utilized by the people of the Water Tribes, who are divided into the Southern, the Northern, and the lesser known Foggy Swamp Tribe, each with their own unique bending style.
Water is the element of change. The moon is the source of power in waterbending, and the original waterbenders learned by observing how the moon pushed and pulled the tides.[1] The Water Tribes are the only people who did not learn bending from an animal, though the Moon and Ocean Spirits took the form of koi fish near the beginning of the avatar world.
The fighting style of waterbending is mostly fluid and graceful, acting in concert with the environment. Foggy Swamp style waterbending, however, is more rigid and straight. Waterbenders deal with the flow of energy; they let their defense become their offense, turning their opponents’ own forces against them.
