definition of rain

Rain is one of the most common and surprising environmental phenomena, even in its simplicity. In scientific terms, rain is nothing more than the precipitation of water from the clouds towards the ground, towards the earth. This fall of water is produced from the condensation of the water vapor that is inside the clouds and that, as it becomes heavier, falls due to gravity towards the ground. Rain is always liquid, that is, it is always water in a liquid state, although it can sometimes be accompanied by other states such as gaseous (for example, with fog) or solid (with hail). Rain, along with sunlight, is essential for life on planet Earth.

When water vapor condenses, it becomes heavier and also colder. Rain is scientifically described as precipitation in the form of drops of around 0.5 mm in diameter. When these drops are smaller, the same phenomenon is called drizzle. In addition, there is also another less known phenomenon related to rain called virga and that is water in the form of drops that does not reach the earth's surface because it does not have enough force.

In addition to the scientific explanation that may exist to explain the phenomenon of rain, it is also important to note that this meteorological phenomenon can really change the existence of living beings, especially humans, for better or for worse. This is so because it is none other than the rain that is responsible for the natural and most effective irrigation that the soils receive. Phenomena such as drought, or the absence of rain, wreak havoc on the land and especially on the generation of crops.

However, rain can also be detrimental if its presence is abundant. Powerful rains (commonly known as storms) can cause major complications such as floods in both urban and rural areas. Many times, the power of a shower can permanently alter the landscape or physical space.
