earth manipulation does not control earth by a certain substance inside it earth is actualy made up of multible substances that is how they control it. earth manipulation is only limited to the purity of certain substances such as pure gold, silver, and iron but steel, coal, and crystal are not pure substances so their a chance to bend it because of the multiple substances it posses.
