Rain is the result of water droplets gathering together in clouds and gravity causing the water droplets to fall as rain. Warm air has more water droplets than cold air.Know More
Rain is part of the water cycle. Air contains invisible moisture called water vapor. This is apparent on warm, humid days.when the air is thick with water vapor. Because warm air can hold more water vapor than cooler air, when the air becomes cooler, excess water vapor is condensed out as water in the form of water droplets. These water droplets are carried up into the clouds and as the clouds become heavy, rain may fall.
Water droplets inside clouds either grow on their own or join up with other droplets to become drops. Millions of drops form in clouds and the clouds can only hold so much water before they become too heavy to hold more. Both gravity and the weight of the water play a part in a rainstorm.
When rain begins to fall, not all of it makes it to the surface. Some of it is blown around and evaporates and some ends up back in the cloud. It will continue raining as long as water continues making the clouds heavy.Learn more about Rain
Acid rain occurs when sulfur dioxide and nitrogen oxides are released into the air where they rise and mix with water, oxygen and other chemicals. Sulfur dioxide and nitrogen oxides dissolve very easily in water and can travel great distances to combine with the moisture in the air.Full Answer >
Rain clouds turn gray or black because thick clouds saturated with rain drops scatter sunlight coming through the clouds. When less direct sunlight gets to the bottom of clouds, they appear darker to the human eye. Thin clouds that do not contain a lot of moisture allow enough sunlight through them so that they appear white to observers.Full Answer >
As of 2014, the rainiest place in the world is Mawsynram, Meghalaya State, India, with about 467 inches of rainfall every year. This small mountain community is soaked during monsoon season every year, with about 90 percent of their annual rainfall falling at that time.Full Answer >
Rain and other forms of precipitation occur when water accumulates in the clouds and falls to the ground. This occurs due to the water cycle, which continually recycles the water on Earth.Full Answer >
