How Does Rain Happens
How Does Rain Happens?
Rain is the primary source of fresh water for most areas of the world. It also provides a suitable condition for diverse ecosystems. In addition, rain water is also for hydroelectric power as well as plants and crop irrigation. Rain provides us life. However, how does rain happen?
1. Initiation
The phenomenon of rain is actually a
water cycle. The concept of the water cycle involves the sun heating
the Earth’s surface water and causing the surface water to evaporate.
The water vapor then rises into the Earth’s atmosphere. The water in the
atmosphere cools and condenses into liquid droplets. The droplets grow
until they are heavy and fall to the earth. The cycle continues when the droplets that evaporated into the clouds gets too heavy and starts falling down.
2. Rain
Rain happens when the droplets of the cloud gets too heavy and start falling. The rain can be in the form of water or snow if the air happens to be too cold. However, not all rain reaches the surface. Some evaporates while falling through dry air. This is called virga, a phenomenon which is often seen in hot, dry desert regions.
3. Collection
The collection stage is where the rain that falls from the clouds starts to gather and collect themselves usually underground or through rivers and other things that flows to the sea and restarts the rain cycle again. There are also water droplets that doesn't make its way underground or to rivers and instead just evaporates by themselves straight to the sky and either form a new cloud or join an existing cloud.
The cycle then repeats after the collection stage when the droplets starts evaporating into the sky and form cloud and then the cycle continues until the sun ends or the water turns dry or the end of the world happened.
