Mother Yun has two little dolls, one is white and the other is crystal clear. They are (snow) and (rain).

Analysis:

1. Snow is characterized by snow, which falls to the ground from mixed clouds.

In mixed clouds, supercooled water droplets will freeze and attach to the surface of ice crystals when they collide with them, making them grow rapidly. When small ice crystals grow up, they overcome the resistance and buoyancy of the air and fall to the ground. This is the so-called snowflake.

2. Rain is characterized by transparency. It falls from the clouds to the ground.

Water on land and sea surface evaporates into water vapor, which rises to a certain height and liquefies into small water droplets when it is cold. These small water droplets form a cloud, where they collide with each other and merge into large water droplets. When it is too big for the air, it falls from the clouds and forms rain.

Extended data:

The formation of rain mainly depends on two means:

1, one is the increase of condensation and sublimation;

2. The second is to rely on the collision and increase of cloud droplets.

In the initial stage of raindrop formation, cloud droplets mainly condense and condense themselves by constantly absorbing water vapor around the cloud. If the water vapor in the cloud can be continuously supplied and replenished, so that the surface of cloud droplets is often in a state of supersaturation, then this condensation process will continue, making cloud droplets grow and become raindrops.

But sometimes the water vapor content in the cloud is limited, and in the same cloud, the water vapor is often in short supply, so it is impossible to make every cloud droplet grow into a larger raindrop, and some smaller cloud droplets will merge into a larger cloud droplet.
