What's the reason for the rain in the sky

summary

With our life getting better today, Why does it rain? We have to understand it anyway. Rain is water droplets falling from clouds. Water on land and sea surface evaporates and turns into water vapor. When water vapor rises to a certain height, it turns into small water droplets when it is cold. These small water droplets form clouds. They collide with each other in the clouds and merge into big water droplets. When they are too big for the air, they fall from the clouds, Rain formed. I'll tell you why it rains.

What's the reason for the rain in the sky

First, because rivers, lakes and seas are exposed to the sun, water becomes steam. Water vapor rises, turns into droplets, and finally into clouds.

Second: the small water droplets or ice crystals that make up the cloud are supported by the lower air flow, and the rising air flow is constantly conveying the water vapor to the cloud.

Third: small water droplets and ice crystals in the cloud collide with each other in motion, and the volume will increase. The water droplets in the lower layer of the cloud gradually become larger. After the volume of ice crystals in the upper layer of the cloud increases, they fall between the water droplets in the lower layer of the cloud, and the water droplets will become larger and larger.

matters needing attention

When the droplets are too big for the updraft to hold them, it will rain. When you go out in rainy days, you must pay attention to your own safety, not too casual!
