It s winter, it s snowing What shape are snowflakes and is snow solid What does snow do

Crystals will have a regular shape. Because snow is crystalline, snow has a fixed shape, roughly hexagonal or hexagonal, and the specific details of the shape are related to the changes in the environment that forms the snow, and different environments create different shapes of snowflakes. The size of a single snowflake is usually between millimeters.

Snowflakes are very light, and the weight of a single is only grams.

Snow is the solid state of water.

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.

The basic shape of a snowflake is hexagonal, but there are almost no two identical snowflakes in nature, just as no two identical people can be found on earth.

Snow is solid. The snow melts and crops can be irrigated.

Snow is solid. But one by one; Big snow: Some look like goose feathers! In winter, the wheat cover is covered with three layers of quilts; Sleep with steamed buns in the coming year!

Reading guide]: Every winter, it will snow when the temperature drops to a certain temperature, many people don't know how snow is formed, and they don't know what shape snow is.

When the temperature drops to a certain temperature, it is usually below freezing, and it snows, do you know how the snow comes from? How is snow formed? In mixed clouds, ice crystals continue to bloom and increase due to the coexistence of ice and water, becoming snowflakes.

When the temperature under the clouds drops below 0, snowflakes can fall all the way to the ground and form snowfall. If the temperature under the clouds is above 0, sleet may occur. There are many shapes of snowflakes, such as stars, columns, sheets, etc., but the basic shape is hexagonal.

The reason why snowflakes are mostly hexagonal and the reason why there are many patterns is because the molecules of ice are hexagonal as the most, for hexagonal flake ice crystals, due to the different curvatures on its surface, edges and corners, they correspondingly have different saturated water vapor pressures, among which the saturated water vapor pressure on the corners is the largest, the second on the edge, and the smallest on the plane. In the case of the same actual water vapor pressure, the condensation growth of ice crystals is also different due to the different saturated water vapor pressures of each part. For example, when the actual water vapor pressure is only greater than the saturated water vapor pressure of the plane, the water vapor only condenses on the surface, forming columnar snowflakes.

When the actual water vapor pressure is greater than the saturated water vapor pressure on the edge, condensation will occur on the edge and on the surface. Because the speed of condensation is also related to the curvature, the condensation is faster in places with large curvature, so the condensation on the edge of the ice crystal is faster than on the surface, and more flakes are formed. When the actual water vapor pressure is greater than the saturated water vapor pressure on the corner, although there are water vapor condensation on the surface, edge and corner, the position at the sharp corner is prominent, the water vapor ** is the most sufficient, and the condensation grows the fastest, so it forms more branch-like or stellate snowflakes.

In addition, the constant movement of ice crystals and the changing temperature and temperature conditions in which they are exposed make the various parts of the ice crystals grow at an inconsistent rate, forming a variety of snowflakes.

Snow is in the shape of a hexagonal flower, and each hexagonal shape is different, if you look closely, there are about a dozen kinds of snow shapes, and most of the snowflakes are hexagonal, because snowflakes belong to the hexagonal crystal system. Snowflakes in the clouds"Embryos"There are two main shapes of Xiaoice crystals. One is hexagonal, long and thin, called column crystal, but sometimes its ends are pointed, like a needle, called needle crystal.

The other is in the form of hexagonal flakes, like the flakes cut from a hexagonal pencil, called flakes. There are so many shapes of snowflakes that each snowflake is an extremely delicate pattern that even many artists have admired.

Xiaoice is changed by the increase of small ice crystals, and the ice molecules are hexagonal for the most, so the formation of snowflakes is mostly hexagonal, and the shape of each snowflake is not exactly the same. The variety of snowflake shapes is closely related to the water vapor conditions at the time of its formation. For hexagonal flake ice crystals, due to the different degrees of curvature on their surfaces, edges and corners, they correspondingly have different saturated water vapor pressures, among which the saturated water vapor pressure on the corners is the largest, followed by the edges, and the smallest on the plane.

How are snowflakes formed? Snowflakes are formed by the condensation of water vapor in the air. In general, water vapor condenses into water before it freezes. Snowflakes are formed directly from the condensation of water vapor.

What color is a snowflake? It seems, the snowflakes are white. Actually, snow is a crystal of ice, and ice crystals are colorless and transparent. But each side of it resembles a small mirror, and its ability to reflect light is very strong, and it shows white color.

How big are snowflakes? The largest snowflakes are more than 2 mm in diameter. Our common goose feather snow, the kind of snow flakes that seem to be formed by many snowflakes sticking together during the landing process.

How much do snowflakes weigh? Snowflakes are very light, weighing only one gram from 5,000 to 10,000 snowflakes. There are between six billion and eight billion snowflakes in one cubic meter of fresh snow.

What is the shape of a snowflake? Snowflakes come in a wide variety of shapes, and each snowflake is a delicate work of art. By now, it is known that there are 20,000 different patterns of snowflakes. It's basically hexagonal though. (Ask Skynet).

Snowflakes come in many shapes and are very beautiful. If you put the snowflakes under a magnifying glass, you can see that each snowflake is an extremely beautiful pattern, and even many artists are amazed. But how are the various snowflake shapes formed?

Snowflakes are mostly hexagonal in shape, and this is because snowflakes belong to the hexagonal crystal system. Snowflakes in the clouds"Embryos"There are two main shapes of Xiaoice crystals. One is hexagonal, long and thin, called column crystal, but sometimes its ends are pointed, like a needle, called needle crystal.

The other type is in the shape of a hexagonal flake, like a thin slice cut from a hexagonal pencil, called a flake crystal.

If the surrounding air is less saturated, the ice crystals will grow very slowly and evenly on all sides. As it grows and falls, it retains its original appearance and is called columnar, needle-shaped, and flake-shaped snow crystals, respectively.

If the surrounding air is highly supersaturated, the ice crystals will not only increase in volume but also change shape as they grow. The most common is to change from flakes to stellate.

It turns out that as the ice crystals grow, the water vapor near the ice crystals is consumed. Therefore, the closer you are to the ice crystals, the thinner the water vapor and the lower the degree of supersaturation. Immediately on the surface of the ice crystals, saturation has just been reached because the excess water vapor has been condensed on the ice crystals.

In this way, the density of water vapour near the ice crystal is less than that farther away from it. Water vapor moves from around the ice crystals to where they are. The water vapor molecules first encounter the corners and protrusions of the ice crystals, where they condense and cause the ice crystals to grow.

As a result, the corners and protrusions of the ice crystals will first grow rapidly and gradually become branch-shaped. Later, for the same reason, new branches and forks grew at the branches and corners. At the same time, in the depressions between the various corners and forks.

The air is no longer saturated. Sometimes, there is even a sublimation process here, so that the water vapor is transported to other places. This makes the corners and branches more prominent, and slowly forms the familiar star-shaped snowflakes.

It is often said that "Ruixue is a mega year". In severe winter, the snow cover covers the ground, keeping the temperature on the ground and around the crops from falling very low due to cold snaps, and the winter crops create a good wintering environment for the potatoes.

When the snow melts, it increases the soil moisture content for the spring growth of the crops. The content of nitride in snow water is 5 times that of ordinary rainwater, which has a certain effect of quietly washing and fertilizing fields. There is a agricultural proverb that "this year's wheat cover is three-layered, and the next year you will sleep with steamed buns".

The snow suddenly fell, and the public happily said: "What does the snow look like? "Brother Hu'er said:

Sprinkling salt can be simulated in the air. The brother and daughter said: "If the catkins are raised by the wind."

Gong laughed. That is, the eldest brother has no daughter, and the wife of General Zuo Wang Ning is also. Translation:

Snowflakes are mostly hexagonal because snowflakes belong to the hexagonal system. The Xiaoice crystals of snowflake embryos in clouds have two main shapes. One is hexagonal, elongated, called columnar crystal, sometimes its ends are pointed, look like needles, called needle-like crystals.

The other is a hexagonal sheet, like a thin slice cut from a hexagonal pencil, called a lamellar crystal. The water vapor in the cloud is not abundant, and the actual water vapor pressure is only greater than the saturated water vapor pressure in the plane, and the water vapor only condenses on the plane, forming columnar snowflakes.

A little more water vapor, the actual water vapor pressure is greater than the saturated water vapor pressure at the edges. Water vapor can condense at the edges and surfaces. Because the speed of condensation is also related to the degree of curvature of Hu Liang, the place with a large degree of curvature will condense faster.

Therefore, the condensation of the edge of the ice crystal is faster than the surface, and then the formation of flake snowflakes, if the water vapor in the cloud is very rich, the actual water vapor pressure is greater than the saturated water vapor pressure at the width of the corner pants, then there is water vapor condensation on the surface, edges, and corners, but the position at the sharp corner is prominent, the water vapor ** is the most sufficient, and the condensation grows the fastest, so many branches or star snowflakes are formed, also called catkins.

Ice crystals are constantly in motion, and their temperature and humidity conditions are constantly changing. This causes the growth rate of the various parts of the ice crystals to be inconsistent, forming various snowflakes. Expanding the use of data snow resourcesIn industry, the snow storage capacity of low-temperature snow storage can be expanded for cooling of production equipment.

Taking advantage of the low temperature of the snow, the snow stored in the snow storage can be mixed in proportion to the output of the high-temperature wastewater, and the snow can be converted into snowmelt water, so that its temperature is kept at around zero, and the equipment is cooled again, so that it circulates back and forth.

For the application of snowmelt water, the use mode of rainwater can also be learned. In the snowfall season, the snow continues to melt, and after it settles, it is concentrated into the pipe, and it is led to various public places for flushing through the water network pipeline, which can reduce a large amount of tap water consumption. Further treatment of snow water can also expand the range of applications of snow water in life.

The shape of the snowflake is related to the crystallization process of water in the atmosphere. When water molecules in the atmosphere cool below freezing, they begin to condense and form ice crystals. Ice crystals have their own regular shapes.

In winter, snowflakes have no fixed shape, they are generally very random, and there are many shapes and types of snowflakes.

There is no fixed shape, each snowflake is different, and if you look closely, you will find that their patterns are very different.

There is no fixed shape, so there is no such statement at all, and such a statement is not correct at all, and the identity is not obtained.
