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.Continue Reading
The air is always filled with tiny drops of water vapor. However, warm air contains more vapor than cool air, and that is why the air is more humid during warmer months. When warm air rises, the water droplets rise. Mountains also cause water droplets to rise, which is the reason why rain occurs frequently in mountainous areas. Clouds form once the air holds plenty of water droplets.
Water droplets and crystals form cluster clouds. After some time, more water is added to the droplets and crystals. When these water droplets become heavy enough, they fall down as raindrops due to gravity. At times, cold air causes ice crystals to retain their frozen form and grow larger to fall as hail, sleet or snow.
Typically, rain occurs as a shower or a drizzle. A shower happens when fast, heavy rain falls for a short period, while a drizzle happens when slow, light rain falls for hours. Raindrops generally fall at a speed of 7 to 18 mph. Aside from water, rain also contains dust, dirt, grass, insects and even chemicals.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 >
According to Met Office, clouds form when water vapor in the air condenses into tiny drops of water or ice crystals that then settle on dust particles in the atmosphere. Condensation happens when the air is saturated and cannot hold any more water vapor; this can occur when the amount of water in the air increases or when the air is cooled to its dew point.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 >
The latent heat of condensation is the energy released when water vapor condenses into water droplets. The process is most readily observed in atmospheric clouds in thunderstorms. According to USA Today, a storm maintains its intensity as thunderclouds release this latent heat.Full Answer >
