Question

what is the relation between the earth and water

Answer 1

These two elements blend well.  Earth needs Water in order to be fruitful and Water can accomplish much more in a medium like Earth than by itself.  Water (Cancer, Scorpio, Pisces) is driven largely by emotion and if they're struggling with a decision that involves both logical and emotional elements, they will side with what their intuition and hearts tell them to do regardless of the facts.  Earth (Taurus, Virgo, Capricorn), on the other hand, will go with logic and what their heads tell them to do, even if their heart is screaming at them to do otherwise.  Thus, when in proper balance, these two can provide two sides of the issue and help arrive at the most appropriate solution.
