earth release is the ability to control the ground around you using chakra, you can force the earth in the way of attacks, or hurl it at the enemy, also you can hide in the ground and move through it...
stong against water, weak against lightning... and in real life, earth is the groud we stand on, the materials we build with, it provides us with the crops and animals we eat
~sits on the cliff and begins to meditate, over the course of a few hours i slowly start mixing my charkra with the earth, acclimitising to the properties of the ground underneath me~
~eventually, i begin to to understand the nature of the earth, and begin to connect with it, the ground arouns me starts to respon to my presence, it starts to shift beneath me, and i start to sink into the ground~
~ builds up a large quantity of earth chakra and uses it to raise a small piller of earth...., it rises slowly at first, but as i gain more control, it rises more rapidly and becomes much sturdier~
~ using the earth from the pillar i just formed, i make a shield of earth, applying a large amount of chakra, i make the shield far more dense that the pillar, making it far tougher~
