What is Rain
Rain is a type of precipitation. The process of accumulated water vapor in clouds falling to the Earth's surface in the form of water droplets is called rain. The reason why raindrops appear to be stretching is dry air. Some of the water droplets passing through dry air during their fall evaporate due to the effect of the dry air, resulting in raindrops appearing to stretch. This phenomenon is called virga. Artificial rain is induced when there is a risk of drought. Artificial rain is achieved by spraying silver iodide into clouds.
How Does Rain Form
Condensation and evaporation processes occur during rain formation. Water bodies on Earth evaporate due to the effect of sunlight. As the evaporated water rises, it begins to cool. Upon encountering a cold air layer, the water vapor starts to condense. Water vapor particles cling to each other, forming clouds. Water droplets that combine and reach a sufficient size begin to fall to the Earth's surface due to gravity. The necessary time for evaporation and condensation for rain to fall is 8 days.
