Rain is a natural phenomenon that is a droplet of water that falls from clouds. Water on the surface of land and sea evaporates into water vapor, which rises to a certain height and liquefies into small droplets. These small droplets make up the cloud, and they collide with each other in the cloud and merge into large droplets.

When it was too big for the air to hold, it fell from the clouds and formed rain.

Rain has a variety of causes, and its manifestations vary from drizzle, to continuous rain, to torrential downpour.

Rain is the most important source of fresh water in human life, and plants must also be nourished by rain and dew to thrive. But flooding caused by heavy rains can also bring great disasters to human beings. With the development of human industrialization, a large amount of industrial waste gas is emitted into the atmosphere, forming acid rain, which has a significant adverse impact on the ecological environment and leads to building corrosion.

The formation process of rain: the water on the ground absorbs heat and becomes water vapor, rises to the upper layer of the sky vapor layer, due to the low temperature of the upper layer of the vapor layer, the volume of water vapor decreases and the proportion increases, the steam falls, due to the high temperature below the vapor layer, the descent process absorbs heat, rises again and cools, and then falls, so that the gas molecules gradually shrink, and finally concentrate on the bottom layer of the vapor layer, form a low temperature zone at the bottom layer, and concentrate the water vapor in the low temperature zone, which forms a cloud. The clouds gradually become larger, the convection up and down inside the clouds becomes more and more intense, the temperature becomes lower and lower, and finally raindrops fall.

The main component of rain: the main component of rainwater is water (chemical formula H2O), there is a small amount of sulfur dioxide (chemical formula SO2), nitrogen dioxide (chemical formula NO2), usually the pH value of rainwater is about, the pH value is less than the rain is acid rain, in case of thunderstorm, the rain will contain a small amount of ozone molecules (caused by lightning), as well as various impurities and floating dust in the air.

When the water on the earth is irradiated by the sun's rays, it becomes water vapor and evaporates into the air. When water vapor encounters cold air at high altitudes, it condenses into small water droplets. These small droplets are small, with a diameter of only millimeters and a maximum of millimeters.

They are small and light, held in the air by updrafts in the air. It was these small droplets of water that gathered together in the air to form clouds. For these small droplets to fall to the ground as raindrops, they would have to increase in size by more than 1 million times.

It should be washed because there is dust attached to the rain.
