In astrology, the elements – fire, earth, air, and water – signify distinct personality traits and behaviors. Fire signs (Aries, Leo, Sagittarius) are passionate and adventurous. Earth signs (Taurus, Virgo, Capricorn) are practical and reliable. Air signs (Gemini, Libra, Aquarius) are intellectual and social. Water signs (Cancer, Scorpio, Pisces) are emotional and intuitive. These elements help us understand compatibility between individuals and describe fundamental qualities of each sign.
