What are the dangers of Antarctic glaciers? What are the characteristics of Antarctic glaciers?

The following dangers may be encountered:

The first type of wind freezing effect: when the human body is at a low temperature, coupled with the influence of cold wind, it will cause heat loss, accelerate and make the human body feel colder, causing danger.

The second type of snow blindness: the human body is in white ice and snow for a long time, and the strong reflection will make the eyes become particularly red and swollen, and it will also lead to vision loss.

The third type of sunburn: because of long-term exposure to concentrated sunlight, holes in the ozone layer and ice and snow surfaces, it will reflect very strong sunshine and sunburn.

The fourth type of Antarctic wind and snow: low visibility makes it difficult for people to control the direction of their progress in strong winds, and thus lose themselves.

The fifth type of ice wave: when people and sleds are on it, it is easy to fall, and when the visibility is low, it makes people feel scared.

The sixth type of ice crevasse: Once you fall into the ice crevice, it is difficult to get out, and you need to connect your companions to each other with ropes and then try to pull them up with ski poles.

Frostbite 7: At extremely low temperatures, it can cause frostbite to fingers without gloves, and when eating, it can also frostbite lips, mouth and teeth.

The total area of the Antarctic continent is 13.9 million square kilometers, which is equivalent to the area of China and the Indo-Pakistani subcontinent combined, ranking fifth among all continents in the world. The entire Antarctic continent is covered by a huge ice sheet, with an average elevation of 2,350 meters, making it the highest continent in the world. There are more than 220 kinds of minerals in Antarctica.

When it comes to glaciers in Antarctica, we all are. Of course, it is very cold in Antarctica, and there are a lot of them, and there will be life-threatening dangers, and if you don't pay attention, it will threaten your life. Snow blindness is the result of seeing white things in the cold for a long time, and after the reflection of sunlight, the eyes will become red and swollen, resulting in decreased vision of the eyes.

Slowly, you will feel that what you see is getting more and more blurry. And then there's when it's cold. Your body's body temperature itself is very low, plus.

The reason for the cold weather, you. The body will become weaker and weaker, if you fall asleep at this time, if you are confused at this time, you can hold on, don't sleep, it's better not to sleep, or you will sleep in the west. Of course, there are a few, for example, if you climb a snowy mountain, the wind is very strong, there is a lot of resistance, so you will feel that you can't go up, or it is difficult to climb up, of course, you will slowly lose your consciousness at this time, lose yourself, so these points you must remember, protect the small family, protect everyone, protect the country This is the duty of all of us, we must protect everyone's life, so that everyone has their own beautiful life, please do not delete it, to more people.

Speaking of glaciers, the vast majority of people on the earth are very unfamiliar with it, they only know a thing or two about it from movies, television dramas, and books, but they have never had the opportunity to witness the magic of glaciers in their lives. Yes, magical. Glaciers are ice that only exist in extremely cold places, and simple snow accumulation forms ice, not glaciers.

The formation of glaciers often takes a long time, requiring snow accumulation to be compacted, crystallized, and then frozen, collided, and compacted to form spherical grains of snow, and then a series of physical changes between the grains of snow, usually taking years to thousands of years to become glacier ice, and then handed over to the years of polishing, and finally become a glacier.

Glaciers don't happen overnight.

Glaciers are found at both ends of the earth, at the north and south poles, and in the high mountains from the poles to the equatorial zone. The formation of mountain glaciers is not simple, it requires not only a sufficient amount of precipitation, but also the requirements for altitude and the shape of the peaks: a certain altitude is required, and the peaks must not be too steep.

The role of glaciers.

We are based on the Earth's landmass, and glaciers alone occupy 11% of the land area and store about 78% of the freshwater resources on the surface. These water resources, although not directly available to humans, are solid reservoirs on the planet.

Far from the ocean, most of the inland rivers are inseparable from the melting of glacial snow, and it can even be said that it is an extremely important supply. Even in some special places, glacial snow melt is the only local water source, such as the Tarim Basin in Xinjiang, China, which is the largest inland basin in China, is a large closed mountain basin, located in the interior of the continent, the climate is dry, rainfall is very little, mainly relying on the Kunlun Mountains and Tianshan Mountains glacier snow melt water to obtain water resources.

Kunlun Mountain Glacier.

In addition, glaciers play an important role in balancing the heat of the earth's surface. Glaciers in the North and South Poles act like giant mirrors that reflect light and heat at the same time, sending them back into space, ensuring that the Earth's heat does not become too high, allowing life on Earth to survive at the right temperature.

Antarctic glaciers are in danger of melting.

It causes sea levels to rise, with impacts on coastal communities. To complicate matters further, different types of melted ice have different effects on the planet. For example, sea ice is associated with direct changes in sea level, but it can reduce solar radiation reflected back into space, which has the consequence that Arctic temperatures rise, causing glaciers and ice sheets to melt faster.

It will cause the global temperature to rise significantly, so that a lot of land will be submerged, and many places will be uninhabitable.

The main characteristics of Antarctic glaciers are as follows:

Enormous scale: Antarctica is one of the largest ice-covered areas in the world, with ice sheets up to 4,700 meters thick, accounting for more than 90% of the world's total ice sheet.

Stable climatic conditions: Antarctica is extremely cold and dry, with little precipitation, and the glaciers formed by the accumulation of snowfall over many years are extremely large, and the rate of formation of glaciers is roughly equal to the rate of melting, which makes Antarctic glaciers extremely long and very slow to respond to climate change.

Floating ice floes: Antarctic glaciers often have ice floes in areas close to the coastline. These ice floes do not affect the sea level height because they are already floating on the surface of the sea.

Hydrogeological features: The water under the ice sheet forms an ice ocean and ice caves, the water and atmosphere in the cave are completely isolated, and the microorganisms and minerals in them are extremely unique.

Complex morphology: Antarctic glaciers have a variety of morphologies, including icebergs, ice sheets, ice shelves, etc. Among them, ice shelves refer to glaciers hanging above the sea and are one of the most significant topographic features of the Antarctic coastline.

People traveling to Antarctic glaciers may encounter the following dangers:

1.Extreme cold and low auspicious temperatures: Extreme temperatures and cold winds can lead to hypothermia and hypothermia, even life-threatening.

2.Altitude sickness: Due to the high altitude of Antarctic glaciers and the lack of atmospheric pressure, people are prone to symptoms of altitude sickness, such as headache, nausea, vomiting, etc.

3.Ice avalanches: There is a large amount of snow and ice in Antarctica, which can cause damage to people.

4.Landslides and fissures: There are irregular fissures and landslides in glaciers, which are potential sources of danger.

5.Animal Attack: There are some wildlife in the Antarctic region, such as seals, penguins, seabirds, etc., and people need to avoid contact with them.

6.Disease transmission: In the Antarctic region, people can be infected with some diseases such as influenza, pneumonia, etc., so personal hygiene and protection need to be taken care of.

Antarctic glaciers encounter many dangers, including:1Ice avalanche beam leakage:

Ice on Antarctic glaciers can suddenly collapse to form huge ice blocks, which can have serious effects on the surrounding environment and organisms. 2.Sea Level Rise:

Glaciers in Antarctica are melting due to global climate change, causing sea levels to rise. This will have a significant impact on the coastline and coastal cities. 3.

Chemical pollution: With increased human activity, glaciers in the Antarctic region may be subject to chemical contamination, especially from exhaust gases and greenhouse gases. 4.

Ecological damage: The environment in which the Antarctic glacier is located is a special ecosystem, and any damage will have a significant impact on that ecosystem. 5.

Dangerous animals in Antarctic glaciers are: seals, killer whales, Antarctic wolves, Antarctic giant insects, skuas, etc.

1. Seals. Seals live in cold temperate oceans and spend the rest of their time swimming, feeding or playing in the sea, except during farrowing, resting and moulting seasons on ice, beaches or rocks. The breeding period is not clustered, after the birth of the young animals, the family group is formed, and after the lactation period, the family group ends.

2. Killer whales. Killer whales are highly social animals, with some groups of families that are the most stable in the animal kingdom. Some of the killer whales' complex social behaviors, hunting techniques, and vocal communication are considered evidence that killer whales have their own culture.

3. Antarctic wolf.

The Antarctic wolf is a native terrestrial mammal that preys on herbivores and rodents that live on the Falkland Islands. In order to adapt to the needs of polar life and hunting, the coat color of the Antarctic wolf changes with the change of temperature; In summer, the coat color becomes darker, some are light yellow, others are red; In winter, the coat color becomes lighter, and some even turn white.

4. Antarctic giant insects.

Antarctic giant insects belong to the class of neomorpha, also known as shoelaces or ribbonworms, and belong to the phylum Neomorpha. Some species are scavengers, but most are very voracious predators, preying on long snouts that emanate from their mouths. Depending on the species, their noses may be poisonous or they may secrete a viscous liquid.

5. Skuas. The skua is very capable of flying, and its posture of spreading its wings and soaring is fierce and fierce, and it is extremely brave, otherwise, the skua can survive in Antarctica, where the environmental conditions are extremely poor. The "thief nature" of the Antarctic skua has been seen since childhood.

They usually lay two eggs at a time, with the first to hatch dominantly.

Underneath the Antarctic glacier, as elsewhere, is mud and rock.

In fact, on the Antarctic continent, glaciers are not the main body, the main body is the ice sheet.

More than 95% of the Antarctic continent is covered by a huge layer of snow and ice, and only the edge of the Antarctic continent has seasonal rock outcrops, and most of the rest is covered with this perennial snow and ice. The average thickness of the ice is about 2,000 meters, and the thickest place reaches 4,800 meters, forming a huge ice sheet, with a total volume of 28 million cubic kilometers of ice and snow, containing about 72% of the world's total freshwater, and in terms of its volume, accounting for more than 90% of the world's total ice, constituting the largest freshwater treasure house on the planet.

In the soil rocks below the Antarctic ice sheet, there are also a large number of mineral resources, mainly copper, platinum, gold, silver, chromium, nickel, diamond and other minerals; The polymetallic metallogenic area of the Trans-Antarctic Mountains contains copper, lead, zinc, gold, silver, tin and other minerals; In addition to a large amount of iron ore, there are non-ferrous metals such as copper and platinum, and kimberlite is found in the East Antarctic iron ore mineralization area. The Prince Charles Hill Iron Mine and the Trans-Antarctic Mountains are considered to be the largest coal mines; The Ross Sea, Weddell Sea, Amundsen Sea, Belinsgaujin Sea and other ocean basins have the greatest oil and gas prospects.
