For ocean and continents
On a global scale, precipitation is most common in the tropical regions near the equator. This is because the warm temperatures in these areas promote evaporation, which leads to the formation of clouds and subsequently, rainfall. The consistent heating of the air and the presence of moisture create a favorable environment for precipitation.
