Rain and other forms of precipitation fall from the clouds. When warm air passes over a body of water, it causes the water to evaporate. Once the water rises high enough, it clumps with other water vapor and becomes a cloud. The air cannot hold an infinite quantity of water, so when the amount of water present in the cloud exceeds the air’s ability to hold it, the water falls in droplets as rain.Know More
On earth, water flows in a constant cycle and none is ever truly lost. The water that falls out of the clouds as rain and strikes the earth flows downhill until it reaches an ocean or lake. Warm air moving over the water will absorb the water, carrying it high into the atmosphere. Because some forms of pollution bond with water, the pollutants can end up in the clouds where it will eventually rain down as polluted water. This can exacerbate the problem of pollution as the rain spreads it to a large area.
Not all clouds are the same, and some types are more likely to produce rain than others. Usually, clouds that produce rain have the term “nimbus” in their name, such as cumulonimbus clouds, which produce thunderstorms.Learn more about Rain
There are many facts about acid rain; one fundamental fact is that it is comprised primarily of nitric and sulfuric acids. There are two types of disposition - wet and dry. Dry deposition means the acid falls in the form of smoke or dust; wet deposition falls in the form of snow, rain and fog.Full Answer >
Air pressure affects the weather by influencing the movement of air around the planet; areas of low pressure generally develop clouds and precipitation, while areas of high pressure tend to bring clear, sunny weather conditions. Air pressure refers to the force exerted by the atmosphere on the surface of the Earth.Full Answer >
Orographic rainfall is rain that is produced from the lifting of moist air over a mountain. The moist air rises and cools, producing orographic clouds, which are the source of the rain. Most orographic rain falls upwind of the mountain range, with some also falling a short distance downwind. This process can produce any type of precipitation, including snow, sleet, hail or freezing drizzle.Full Answer >
Rain water absorbs carbon dioxide from the air it passes through on its way down. The carbon dioxide reacts with the water to form carbonic acid. This mechanism is one of the principal ways in which atmospheric carbon is scrubbed from the air and put back into circulation among living systems.Full Answer >
