In the middle of winter, when much of Europe and North America are covered in snow, it's interesting to learn more about the phenomenon of snowfall to better understand it. For this reason, we're going to tell you about it. 4 curiosities about snow that will surely surprise you. Let's learn more about her.
Snow can be pink
Normally, snow is white because the surface reflects sunlight, sending it back into space. However, it may also be pink due to the presence of a microalgae called Chlamydomonas nivalis, which can reach millions of individuals per centimeter of snow. This can be observed in several mountainous regions. To learn more about this curiosity, visit the article on what is pink snow. Snow can also take on other colors if it mixes with environmental pollution, making it a striking visual phenomenon.

In addition, these curiosities have been the subject of study in various investigations on climate and curiosities related to winter.
A snowflake is not a mineral
From a scientific point of view, a mineral is a homogeneous solid that has a defined chemical composition and an ordered atomic arrangement. On the other hand, Ice is not the usual state of water, and liquid water doesn't have an ordered structure, so snowflakes aren't considered minerals. Furthermore, each snowflake is unique, with a shape that varies depending on the climatic and environmental conditions under which it forms. For more information on this phenomenon, you can consult what is snow, where you will learn more about the fascinating world of snowflakes and other aspects of the curiosities about snowflakesThe properties of snowflakes are a subject of fascination and study in the field of meteorology.
China celebrates the biggest snow festival
Harbin, China, hosts the Ice and Snow Sculpture Festival, an event that has taken place annually since January 1963. During this festival, residents and visitors alike enjoy impressive sculptures made of snow and ice, preserved thanks to the region's low temperatures, which hover around -18.3°C during the first month of the year. This event attracts tourists from all over the world, making Harbin an iconic winter destination.

It snows on other planets
It might surprise us to think that it only snows here, on planet Earth, but that's not the case. Snow also falls on Mars and Venus, although not in the same way as we see on our planet. On Mars, snow is composed of carbon dioxide and falls as fog during certain times of the year. On Venus, on the other hand, snow is pyrite, a mineral that vaporizes due to the high temperatures of the atmosphere. These peculiarities show how snow, although familiar to us, can manifest itself in completely different ways on other worlds.

More curiosities about snow
- Snow isn't actually white. As we mentioned earlier, snow is colorless, but its white appearance is due to the way light reflects off its crystals.
- Surprisingly, 75-80% of the Earth's freshwater is found in the form of ice or snow, including glaciers.
- Snow can fall in different forms, including sleet (a mix of snow and rain) and cilantro (granulated snow).
- Sapporo, Japan, is known as the snowiest city in the world, with an annual average of 595 cm of snow.
The impact of snow on the environment
Snow plays a fundamental role in the Earth's climatic balance. Its presence has multiple effects, such as albedo effect, where snow reflects 80-90% of sunlight, helping to regulate the Earth's surface temperature. This is crucial for maintaining a stable climate in cold regions and also influences global warming. You can learn more about the global warming and its impact in the characteristics of the snow and the weather.
It's important to note that melting snow is a vital resource, providing essential water to rivers and lakes, which are crucial for ecosystems, agriculture, and human consumption. Furthermore, snowdrifts have a high thermal insulation capacity. This allows animals, for example, to use snow to build shelters during the winter. The insulating properties of snow allow animals such as polar bears and snowshoe hares to insulate themselves from the intensely harsh cold that characterizes their environment. You can learn more about these animals at the coldest countries on the planet, where the impact of the cold on wildlife is also discussed.
Despite its beauty, snow can also be dangerous. One of the risks associated with snow is its ability to reflect ultraviolet radiation, which can cause a condition known as photokeratitis, which causes painful inflammation of the cornea and can lead to temporary vision loss. Therefore, it is recommended that those who spend time outdoors in snowy conditions wear protective eyewear.
Additionally, snow can be a trigger for avalanches, especially in mountainous areas. Accumulated snow can become unstable, leading to dangerous slides that can endanger the lives of skiers and mountaineers. Education about snow conditions and the use of proper equipment is crucial for enjoying snow activities safely. You can also educate yourself about other activities and the specifics surrounding them.
More interesting facts about snow
There are many more interesting facts about snow that most people didn't know:
- The largest snowflake ever recorded had a diameter of 38.1 cm and was registered at Fort Keogh, Montana, in 1887.
- Snow has been documented in very unusual places, such as the Sahara Desert, where snowfall was recorded in 2016. This shows that snow can be present in unexpected areas like the Sahara.
- World Snow Day is celebrated every third Sunday in January around the world, promoted by the International Ski Federation.
- Each winter, it is estimated that around a quadrillion snowflakes throughout the northern hemisphere.
Understanding snow goes beyond enjoying a winter landscape; it's essential to understand its formation, its environmental impact, and the precautions necessary to interact with this natural phenomenon safely and responsibly. By learning about snow, we enrich our connection with the environment and recognize its importance not only in the climate but also in our daily activities, from sports to agriculture.
