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
Rain is made when water vapor in the air condenses, and the water droplets become too heavy and fall rain drops. When a mass of air cools to saturation point, it leads to condensation of the water vapor, which forms clusters of water droplets and frozen water crystals.Full Answer >
Mist forms when water droplets in the air cool suddenly. These droplets, which were a gas at a higher temperature, suddenly become visible when cooled. Very similar to fog, this often occurs when air seated over warm water comes into contact with cool, dry land.Full Answer >
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 >
