The Earth signs are normally not prone to physical violence, but as in any situation, there are exceptions. They are mildly revengeful. Their attitude is 'my time will come and they do hold a grudge. They will eventually get their revenge one way or another more often by hitting a person in his pocketbook. When angered, Earth signs, similar to the Fire and Air signs, are quick to express that anger verbally though most likely not physically unless as a last resort.
Air signs resort to trickery.
These people are crafty, under handed and ingenious when it comes to evil. They are also prone to physical violence. Whereas the Fire signs' anger is generally of the moment and soon after forgotten, the Air signs at their worst are mean. They carry a grudge, and like Fire signs, they are quick to express their opinion and are very opinionated. Aquarius and Libra are not as violent as Gemini.
