As a natural phenomenon, snow has brought many wonderful and magical experiences to people's lives. Among them, the formation, characteristics, functions of snow and its relationship with human beings.
First, the formation of snow
Snow is a beautiful crystal, which sticks together in the process of falling and forms snowflakes. Snowflakes have different shapes, such as plates, needles and columns, but no matter how small and wonderful, their crystals are regular hexagons. The single size of snowflakes is usually between 0.05 and 4.6 mm, and the weight is only 0.2-0.5 g.
Second, the characteristics of snow
1. Snowflake: Snowflake is a beautiful crystal, which gathers together and links together in the process of falling, forming our common snowflake.
2. The shape of snow: Snowflakes have different shapes, such as plates, needles and columns, but no matter how small and wonderful, their crystals are regular hexagons.
3. Color of snow: The newly fallen snow is usually white. This is because snowflakes contain a lot of bubbles, which makes the reflectivity of snowflakes high. When the sun shines, all colors of light are reflected to form white snow.
Third, the role of snow.
1. Benefits of crops: Xue Rui heralds a bumper harvest year, which is an agricultural proverb widely circulated in China. In the north, a thick layer of loose snow is like covering wheat with a quilt to keep out the cold. Nitrogen contained in snow is easily absorbed and utilized by crops. The low temperature of snow water can freeze the overwintering pests on the surface and bring benefits to agricultural production.
2. Impact on the environment: Snow can purify the air and slow down the greenhouse effect. Snow water permeates the soil, which is equivalent to applying nitrogen fertilizer to the soil once, which helps to improve soil fertility.
3. Impact on human life: Snow has brought many wonderful experiences to people's lives, such as skiing, making snowmen and having snowball fights. In addition, snow also has a certain impact on traffic, such as road icing and flight delay.
Fourth, the relationship with human beings
1. Culture: Snow, as a natural phenomenon, is of great value in artistic fields such as poetry and painting. The ancients said that "there are five flowers in the grass and six flowers in the snow", which reflected people's love and praise for snow.
2. Economy: Snowfall has a certain impact on agriculture, tourism, transportation and other industries. For example, agriculture benefits from snow water and snow scenery to attract tourists, but at the same time, road icing and flight delays will also bring certain losses to the economy.
3. Life: Snow has brought many wonderful and magical experiences to people's lives, such as skiing, making snowmen and having snowball fights. At the same time, snow also affects people's lives, such as icy roads and flight delays.
In a word, snow, as a natural phenomenon, has rich characteristics, extensive functions and close relationship with human beings. Since ancient times, snow has always attracted people to explore, appreciate and praise.
