Rain Facts
Our planet earth is the most unusual one in the entire solar system as it has an atmosphere that contains moisture. This moisture stays gathered in clouds and lastly falls as snow, hail or rain. This fall of moisture is known as precipitation. Rain does not always make the ground wet. In extremely hot and dry places, it evaporates even before it hits the ground. Although, rain also occurs on other planets in our solar system but it is very much different to the rain we experience here on earth. There, rain is made of sulphuric acid or methane.
