How heavy is the cloud? Why does the wind disperse when it blows?

Cloud is a visible polymer floating in the air, and it is a mixture of small water droplets or small ice crystals formed by surface liquefaction after water evaporates and rises under sunlight. They are light, so they can be suspended in the air. If the weight of water drops is too heavy, they will fall from the air. This is the rain we see. How light are they? When the wind blows gently, they will float freely in the air. This is the natural landscape we usually see, and the clouds seem to walk in the sky.

Clouds are the product of the earth's water cycle. Under the irradiation of the sun, the water on the earth changes from liquid to gas and rises from the ground to the air. Because the temperature in the air is relatively low, water vapor will liquefy into small water droplets or condense into small ice crystals during precooling. These mix together to form the clouds we usually see. Clouds are different in shape and height. The existence of clouds is very important to the earth. When night falls, the heat on the earth drops rapidly. Clouds can prevent excessive heat loss and return their stored heat to the surface, which is beneficial to the insulation of the earth. When the sun shines very strongly during the day, the existence of small water droplets and small ice crystals in the cloud will scatter the sun around, so that the temperature of the surface will not rise so fast, which is conducive to cooling down.

Due to the backwardness of ancient science and technology, through long-term observation and practice, people found that the weather can be judged by the changes of cloud shape, direction, moving speed, thickness and color, and whether there is rain, snow, ice and hail can be judged according to these findings, which brought great convenience to production and life. And made up many proverbs in practical application, such as? Kareem abdul-jabbar, is it raining? 、? Carp spots in the sky, no need to turn over the valley in the sun? Wait, these are the crystallization of the wisdom of the ancient working people in China.

Clouds are the product of the water cycle, which is very important to the earth. Its mass is so light that it can be suspended in the air.
