Who has information about snow? What information is there about snow?

There are a lot of people calling snow, which one do you mean?

Snow snow snow snow.

What are you talking about???

Snow can be heated when water is drunk.

40 bits. Snow.

Snowflakes are beautiful crystals that cling together in clumps as they fall, forming snow flakes. The size of a single snowflake is usually between millimeters. Snowflakes are light, weighing only grams individually.

No matter how light and small the snowflakes are, how wonderful they are, its crystals are regular hexagonal shapes, so the ancients had the saying that "there are more than five flowers of plants and trees, and six snowflakes are produced". How beautiful and light the snowflakes are! I'm getting more and more fond of snowflakes, and it would be a pleasure to see the land covered with snow and the trees covered in silver again.

"Ruixue Zhaofeng Year" is a widely spread agricultural proverb in China. In the north, a thick, loose layer of snow covers wheat like a quilt to keep the wheat warm. The nitrogen in the snow is easily absorbed and utilized by crops.

The low temperature of snow water can freeze the pests that overwinter on the surface, and it also brings benefits to agricultural production. Therefore, there is another agricultural proverb: "In winter, the wheat covers the three-layer quilt, and the next year sleeps with steamed buns." ”

Snow has a wide range of effects, but snow has great benefits for humans. First of all, it is conducive to the growth and development of crops. Because snow conducts heat very poorly, the soil surface is covered with a snow cover, which can reduce the transfer of soil heat and block the invasion of cold air on the snow surface, so the crops protected by snow can safely overwinter.

Snow also stores water for crops. In addition, snow enhances soil fertility. It has been determined that every 1 liter of snow water contains about grams of nitrogen.

When snow water penetrates the soil, nitrogen fertilizer is applied once. Feeding livestock and poultry with snow water and irrigating crops can yield significant benefits.

Snow is both good and bad, and in the middle of spring in March and April, there is a sudden cold wave that causes heavy snowfall. It will cause freezing cold. Therefore, the agricultural proverb says: "Wax snow is a treasure, and spring snow is not good." ”

Friends, after listening to my introduction, do you like and understand snow more?

Snow is a type of water that condenses at extremely low temperatures.

Snow is a very cold nature, phenomenon.

Snow, am I okay???

Snow is a natural phenomenon in which water condenses in the air and then falls.

Snow is a natural phenomenon in which water or ice condenses in the air and then falls, or snowflakes that fall. Snow is a form of water in a solid state. Snowflakes are formed by tiny ice crystals colliding and sticking together in clouds to form a variety of shapes.

No two snowflakes are exactly the same, but the snowflakes still adhere to the basic hexagonal symmetry of the original ice crystals. Through the microscope, you can see that most of the intricate structures of snowflakes are hexagonal, and the center of the snowflake must show a symmetrical hexagon, and the reason why it has such a shape is that it is arranged in the most efficient way on the plane, and it is one of the objects of crystallography research.

When the weather is very cold, the ice crystals do not stick together easily, and the snow is small droplets of fine powder. A closer look at the shape of the snowdroplets shows that the small snow droplets are formed by the accumulation of many fine white ice particles. As the cold air moves forward and the updrafts weaken, the water vapor in the clouds condenses directly on the ice crystals into larger forms, which are known as snowflakes.

If the temperature is close to freezing, Douyu will fall wet snow, forming large snowflakes, especially when there is no wind. Large star-shaped snowflakes can be 5 to 7 cm in diameter. Most snowflakes melt into rain on the way down to the ground, and only when the air close to the ground is cold enough can the snowflakes fall to the ground and form snow.

Snow is formed by direct condensation of water vapor from the atmosphere. The low temperature in the clouds causes the water vapor to form ice crystals, and when the temperature is low enough, the ice crystals fall to the ground and are still snowflakes, which is snow. Snow absorbs heat as it melts, so the ground air temperature will be lower when it melts than when it snows.

Snow forms under the condition that the atmosphere contains cold ice crystal nuclei, sufficient water vapor, and a temperature below 0 (freezing).

Briefly. Snow is a type of precipitation that is a crystalline solid ice that falls from the branches of clouds, often in the form of snowflakes. Snow is made up of small ice particles and is a granular material that has an open structure and therefore appears soft.

Because of the different temperatures and humidity, the snowflakes that form come in a variety of shapes and sizes. If the snow melts and then freezes again during the landing, it will form a ball of snow, which can be hazel, graupel, and hail.

In Lu Xun's "Snow", the snow in the south of the Yangtze River is beautiful, but in the eyes of the author, this beauty has not been tempered and cannot be maintained for a long time, and he values more than a spirit of independence and individuality.
