In astrology, each of the 12 zodiac signs have unique traits that make the signs different from one another. However, there are two commonly used ways to group the signs in order to add depth to a birth chart reading.
Each zodiac sign falls into one of the three modalities (cardinal, fixed or mutable) and into one of the four elements (fire, earth, air, and water). For instance, Aries is a cardinal, fire sign. Taurus is a fixed, earth sign an so on.
In the exercise below, you can test your knowledge of modalities and elements by filling in the blanks.
