Fire represents energy and friendliness. Fire signs are generally enthusiastic, self-confident, assertive, courageous, and generally love life and all of its aspects.
 

Air Signs (Gemini, Libra, and Aquarius)

Air, like Fire, represents the rising of energy and extreme friendliness. Air is spacious and free-moving, symbolizing thought and intelligence. These signs are extremely thoughtful, analyzing most of what they see or hear. Sometimes they become detached and forget that their greatest ally is the ability to communicate their ideas.
 

Water Signs (Cancer, Scorpio, and Pisces)

Water tends to be introverted, and represents energy going downwards. Water signs are generally in tune with their emotions and have extremely powerful imaginations and feelings.
 

Earth Signs (Taurus, Virgo, and Capricorn)

Earth signs usually keep to themselves, and like Water, represent energy moving downwards. Earth signs are practical, solid, down-to-earth (no pun intended), and concerned with the material world in general.
